SAD - Seasonal Affective Disorder 101

The first formal description of Seasonal Affective Disorder (SAD), the most well-known psychiatric condition associated with seasonality in humans, was introduced in the mid-1980s by Rosenthal, who described a group of 29 patients living in a temperate climate who experienced depressive episodes characterized by hypersomnia, hyperphagia, and weight gain in the fall or winter, and whose symptoms remitted by the next spring or summer.

SAD was incorporated into the Diagnostic and Statistical Manual (DSM) of Mental Disorders III-R when “seasonal pattern” was introduced as a specifier for Major Depression and Bipolar Disorders. Subsequent revision in DSM-IV described SAD as “a regular temporal relationship between the onset of Major Depressive Episodes in Bipolar I (BPI) or Bipolar II (BPII) Disorder or Major Depressive Disorder (MDD), recurrent, and a particular time of the year.”

Today, SAD, or MDD with seasonal pattern, is defined as recurrent episodes of major depression that meet the following criteria: at least two consecutive years where the onset and offset of depressive symptoms occur at characteristic times with no non-seasonal episodes, a temporal relationship between onset of symptoms and time of year, a temporal relationship between remission of symptoms and time of year, and an outnumbering of seasonal compared to non-seasonal episodes throughout the lifetime of the patient.

Pathophysiology of SAD

To date, the pathophysiology of SAD is unclear. Early research into the mechanism of SAD focused on day length or photoperiod. This hypothesis posited that shorter days in winter, possibly mediated by a longer duration of nocturnal melatonin secretion, leads to depressed mood in susceptible individuals. To date, there is little data to support this hypothesis. Furthermore, given that bright light in the evening has not been as effective as that given in the morning, it now seems unlikely that the photoperiod is the underlying pathological mechanism of SAD.

Although some animal studies have implicated a direct effect of light on the midbrain (Miller, Miller, Obermeyer, Behan, & Benca, 1999; Miller, Obermeyer, Behan, & Benca, 1998), the most prominent hypothesis driving human studies involves disruption of circadian rhythms. Research on the role of serotonin is also active.

Circadian Rhythm

A circadian rhythm refers to the approximately 24-hour cycle of physiological processes present in humans and other animals. This cycle is governed via clock gene expression by the suprachiasmatic nucleus (SCN), the master pacemaker located within the anterior hypothalamus. Though the SCN endogenously generates circadian oscillations, SCN endogenously generates circadian oscillations, and they need to be entrained to the 24-hour day by external cues. Light exposure is the most important synchronizing agent of endogenous circadian rhythms.

Downstream of the SCN, a collection of systemically active neurohumoral networks transduce circadian information to the rest of the body. For instance, via projections to the hypothalamus's paraventricular nucleus, the activation of the SCN leads to autonomic changes, including cardiovascular modulation, and together the central, peripheral, and autonomic nervous systems collaborate to affect systemic changes. Thus, the SCN receives information about the external day-night cycle directly through retinofugal pathways and indirectly through neuromodulatory signaling. Circadian information is then relayed systemically through neurohumoral networks.

The current primary hypothesis for the pathophysiology of SAD, known as the “phase-shift hypothesis,” posits that there is an optimal relationship in the alignment of the sleep-wake cycle and the endogenous circadian rhythm. During the fall and winter, as day length shortens, the circadian rhythm begins to drift later concerning clock time and the sleep-wake cycle. This phase delay is hypothesized to bring about mood symptoms. A pulse of morning bright light generates a circadian phase advance, which is thought to correct the discordance between sleep and circadian phase, thereby ameliorating depressive symptoms. However, the phase-shift hypothesis would predict that the amount of phase correction required for each patient would depend on an individual’s PAD, which has not yet been proven.

Serotonin

Several studies have also proposed that serotonin is implicated in the pathophysiology of SAD, as selective serotonin reuptake inhibitors (SSRIs) appear to be effective in the treatment of SAD. Supporting this hypothesis, one study used Positron Emission Tomography (PET) imaging to look at binding probability at synaptic serotonin transporters in 88 normal individuals living in the temperate climate of Toronto, Canada (Praschak-Rieder, Willeit, Wilson, Houle, & Meyer, 2008). The binding probability was increased during fall and winter compared to warmer months, thus eliciting an inverse correlation between binding potential and sunlight durationsunlight duration. Of note, the largest difference in transporter binding was found in the mesencephalon, a finding consistent with animal studies demonstrating the importance of direct effects of light to the midbrain on behavior. If increased transporter activity indicated greater reuptake of serotonin during the fall/winter, and if this resulted in a lower density of cleft serotonin, then the seasonal variation in transporter activity (i.e., higher transporter efficiency in the winter) would seem to leave susceptible individuals particularly prone to mood symptoms during the darker seasons. Moreover, following BLT and during periods of remission in the summer months, the synaptic transporter activity was shown to be reduced to control levels in these patients.

Eating Disorders

BLT has also been investigated to a lesser extent in eating disorders. Because binge eating episodes have been observed to increase in fall and winter in some patients, BLT has been examined as a treatment modality for anorexia nervosa (AN) and bulimia nervosa (BN). Thus, BLT's effects on patients with eating disorders remain enigmatic. Additional studies, including larger, randomized, blinded, and controlled trials, are needed to elucidate further the role of BLT in treating this patient population. Further research might also determine whether BLT would be a useful treatment in Binge-Eating Disorder, a diagnosis new to DSM-5.

Adult ADHD

Additionally, BLT has been studied in the context of adult Attention-Deficit/Hyperactivity Disorder (ADHD), where, in addition to normal ADHD symptoms, patients often have depressed mood and difficulties falling asleep, awakening on time, and maintaining arousal (Brown & McMullen, 2001). These symptoms are indicative of a possible delay in the circadian rhythm. A case report of symptom improvement following BLT in a child with ADHD who displayed signs of delayed sleep phase also supports the idea that BLT may be useful in treating symptoms of ADHD (Gruber, Grizenko, & Joober, 2007). Whether the pathways that subserve the improvement of mood symptoms in response to BLT are the same pathways that underlie the seemingly beneficial effects of BLT in ADHD remains to be studied. While these results are promising, further studies, preferably in randomized, blinded, and controlled studies will need to be performed.

Finally

A significant immediate reduction of depression scores with light treatment can be identified after 20 minutes and reaches the maximum at 40 minutes, with no additional benefit at 60 minutes. The rate of change is steepest during the first 20 minutes of light as compared with longer intervals. Comparing the clinical impact of these durations of administration may yield different results when measured after several daily sessions. The overnight effect on circadian rhythms and sleep was not assessed in our study and is thought to impact mood regulation in SAD. Larger, prospective, controlled, and hypothesis-driven studies in more naturalistic conditions would be desirable to replicate our study results and our study results and analyze the temporal dynamic of the persistence of the immediate mood-improvement effects. Besides, in larger samples, one could define early responders and nonresponders, analyze genetic (e.g., melanopsin related genes), demographic (children, adolescents, adults, elderly, gender), physiological (e.g., pupillary responses), and clinical (e.g., abundant atypical symptoms) predictors for early response. If proven effective and efficacious, shorter exposures to bright light could become a feasible and broadly employed intervention for immediate mood improvement as an early step on the road toward full antidepressant response and remission.

Light Therapy & Sleep Quality: The Secret of the Chinese Female Basketball Players

Good sleep is a prerequisite for optimal performance. Given that people spend about one-third of their lives asleep, sleep has substantial development, daily functioning, and health. Perhaps no daytime behavior has been associated more closely with improved sleep than exercise. Researchers have shown that exercise serves as a positive function for sleep. Regular exercise consistently has been associated with better sleep. Moreover, the American Academy of Sleep Medicine considers physical exercise a modality of nonpharmacologic treatment for sleep disorders. When studying the influence of exercise on sleep, most investigators have compared acute and sedentary control treatments. In the study of regular moderate-intensity endurance exercise, researchers also provided compelling evidence that exercise promotes sleep.

However, exercise can negatively affect sleep quality. Exercising immediately before going to sleep is detrimental to sleep quality. Athletes train very hard to improve their on-field performances, but excessive training may decrease performance, known as overtraining syndrome. Researchers have shown that symptoms of overtraining indicate poor-quality sleep. Good sleep is an important recovery method for the prevention and treatment of overtraining in sports practice.

In a recent study in which red-light therapy (wavelength = 670 nm, light dose = 4 J/cm2) was used, researchers indicated that red light could restore glutathione redox balance upon toxicologic insult enhance both cytochrome c oxidase and energy production, all of which may be affected by melatonin. Melatonin is a neurohormone that is produced by the pineal gland and regulates sleep and circadian functions. No one knows whether sleep is regulated by melatonin after red-light irradiation in athletes. Researchers have demonstrated that phototherapy improves muscle regeneration after exercise. A red light could protect human erythrocytes in preserved diluted whole blood from the damage caused by experimental artificial heart-lung machines.

Participants

Twenty female athletes of the Chinese People’s Liberation Army team (age = 18.60 ± 3.60 years) participated in the study. All participants were healthy and were not using medications regularly or temporarily during the measurements. Athletes were excluded if they had participated in less than 80% of the scheduled team physical training and basketball sessions for the last 3 months or used any nutritional supplements or pharmacologic agents. All participants provided written informed consent, and the Ethical Committee approved the China Institute of Sport Science study.

Design

Participants were assigned randomly to either a red-light therapy intervention group (n = 10) or non–red-light therapy intervention group (placebo group, n = 10). Measurements were collected at preintervention (baseline) and postintervention (14 days). The exercise training schedule of the 2 groups was unchanged during the 14 days; the red-light treatment group used a red-light therapy instrument every night for total body irradiation for 30 minutes. The training routine of the athletes during the 14 intervention days included 12 exercise sessions with the following specifications: 2 hours of morning training, 2 hours of afternoon training, and no training on Sunday.

The red-light treatment participants lay in the supine position. Continuous illumination was performed using noncoherent red light from a whole-body red-light treatment machine-like Kaiyan’s red light therapy bed, with an average wavelength of 658 nm and a light dose of 30 J/cm2. The whole body received the phototherapy treatment. The placebo participants also lay in the supine position under the red-light device but did not receive any light illumination. All participants wore swimsuits to enhance irradiation from the device and were blind to the treatment.


Measurement

Sleep Quality

The Chinese version of the PSQI measured sleep quality. The 19-item measure assesses sleep quality and disturbances over a half-month time interval. The total PSQI score ranges from 0 to 21, and higher scores reflect poorer-quality sleep. The 7 items of this instrument measure several aspects of insomnia: difficulties with onset and maintenance of sleep, satisfaction with the current sleep pattern, interference with daily functioning, noticeable impairment attributed to sleep problems, degree of distress, and concern caused by any sleeping problems.

Cooper 12-Minute Run

Participants were instructed to complete as many laps as possible on a 400-m outdoor track during the 12-minute test period. Emphasis was placed on pacing oneself throughout the test. The test administrators counted the laps completed during the 12-minute test period while calling out the time elapsed at 3, 6, and 9 minutes and orally encouraging the participants. At the end of the 12-minute period, the test administrator instructed the participants to stop and used a measuring wheel to determine the fraction of the last lap completed by each participant. This distance was added to the distance determined by the number of laps completed to give the total distance covered during the test.

Serum Melatonin

In humans, the serum level of melatonin, derived mainly from the pineal gland, demonstrates a clear increase at night and a decrease during the day. Given that the masking effects of activities (e.g., exercise, sleep, and food intake) have little effect on the circulating melatonin level's daily pattern, melatonin secretion appears to directly reflect the function of the biological clock as a specific marker of the circadian rhythm.

Conclusions

The study has demonstrated that red-light illumination positively affected sleep quality and endurance performance variables in Chinese female basketball players. Based on previous studies, we can infer that red-light treatment contributes to increased melatonin secretion in the pineal gland and muscle regeneration. Although more studies involving phototherapy, sleep, and exercise performance need to be performed, red-light treatment is a possible nonpharmacologic and noninvasive therapy to prevent sleep disorders after training.

Neonatal Care Taps into Light Therapy

When a baby is born, all parents hope for a healthy child—all ten fingers and toes, a strong heart, and an able body. However, between 10 and 15 percent of babies born within the U.S. require special care within the NICU (Neonatal Intensive Care Unit), which is where preterm or diseased babies are cared for. 

This time is crucial for babies; it's the stage in which we, as humans, are most sensitive. After the first hour of life, newborns should receive eye care, vitamin K, and recommended immunizations (birth dose of OPV and Hepatitis B vaccine). They should be assessed for birth weight, fetal age, congenital disabilities, and newborn illness signs. Special care is provided for sick newborns, preterm and/or low birth weight, and babies exposed or infected by HIV or have congenital syphilis.

One of the more common diseases for premature babies is jaundice, which refers to the yellowish discoloration of the skin, sclerae, and mucous membranes caused by an increase in bilirubin in the blood. This substance derives from the metabolism of hemoglobin contained in red blood cells. For the newborn, it is (in most cases) destined to disappear within a few days.

Jaundice becomes evident when the amount of bilirubin exceeds 3 mg per deciliter. The yellowish color occurs first in the face and sclerae (the white part of the eye) and then extends to the trunk and upper and lower limbs. Jaundice can be physiological or indicate a pathology.

However, jaundice can become severe. This happens when it goes untreated for too long, it can cause a condition called kernicterus. Kernicterus is a type of brain damage resulting from high levels of bilirubin in a baby's blood. It can cause cerebral palsy and hearing loss.

Babies are naturally sensitive, and premature newborns are even more at risk. Their immune systems are still developing due to being born prematurely, which increases their risk of getting sick. Skin conditions of many kinds are common; in addition to jaundice, many experience feeding issues, and fever (always the first sign of an infection). 

Due to the nature of premature babies, it's essential to consider a non-invasive, non-medical treatment. They're still growing, just fully coming into their own and catching up on time missed developing in mom’s belly. 

Light therapy is an incredible tool for these little humans, working inward and targeting the cellular level. It helps with both external and internal problems, which means that at the cellular level, light therapy alters and enhances the cell constitution. This, as a result, leads to faster and better reproduction, creating a healthier and stronger organism and body to function with. 

Light therapy is a non-invasive, non-pharmaceutical form of therapy. The way it can help with neonatal care is unique. During treatments, the babies are completely safe and protected, with their eyes covered. The skin gets exposed to the light therapy lamp to absorb its benefits. The lamp is positioned specifically for the baby, no closer than 30.5cm. 

Light therapy has successfully treated newborn jaundice by lowering the bilirubin levels in the baby's blood through a process called photo-oxidation. Photo-oxidation adds oxygen to the bilirubin, making it dissolve in water easily. 

Since light therapy also helps to regulate circadian rhythm and melatonin, the treatments can also help babies sleep, which is essential in their healing and development. 


You can customize and completely control light therapy consumption for babies, thanks to Kaiyan Medical’s state-of-the-art light therapy device manufacturing services. We have been working for 15 years to produce the best light therapy products on the market which are MDA-certified and FDA-approved light therapy devices, many of which are cleared for at-home treatments. Of course, before using a light therapy device, always consult your doctor.

College Students use Light Therapy to Improve Seasonal Affective Disorder (SAD)

The life of a college student is taxing, to say the least. It's likely the first time you're doing something on your own, and are responsible for yourself, your schedule and lifestyle. For some, this is the most liberating time; for others, it’s incredibly overwhelming. However, there's a general agreement that college students all go through difficult times. 

Whether still living with parents or sharing a dorm or space with roommates, college students are immersed in an entirely new life experience. Classes are challenging and students struggle with getting their work done while maintaining a social life, and perhaps a job. The level of pressure to succeed is very demanding, and this can cause negatively associated thoughts, leading to stress. Eating habits change and alter, usually for the worst, not to mention that the new sense of freedom can be chaotic for many young adults. 

Taking care of yourself is the number one priority, and when learning to deal with the new load of responsibility, college students often get sidetracked. Health and self-care get only an ounce of attention and not nearly as much as it should. While many students think it takes a lot of effort, just starting small shows results. 

Stress is the precursor of everything in our body, and leads to all sorts of illness and disorders. It's pretty common for college students to experience stress; more than 40% of students claimed to have experienced above-average stress levels, with it getting worse during exam periods and the winter season, when even more time is spent indoors. All of this, compounded by a pandemic and social distancing, makes for extremely challenging circumstances for college students today.

Now, colleges such as the University of Iowa are turning to light therapy to help get students the light they need to continue thriving. 

Seasonal affective disorder (SAD) is a mood disorder that occurs annually, generally in fall and early winter, and ends in sunnier and warmer months of spring and early summer. However, it’s worth noting that it’s not a perfect formula; there have been reported cases of the opposite, where a person starts experiencing the disorder spring or summer, and it only ends with the arrival of fall/winter. 

SAD can affect 11 million people in the U.S. each year, and 25 million more may have a milder form of the same disorder, also known as winter blues. Depression and anxiety affect 40 million adults in America, while only 36.9% receive the proper care for these mental health conditions

And, SAD’s symptoms can look and feel much like depression. It causes you to sleep more and gives you symptoms that look like other disorders such as chronic fatigue syndrome, under-active thyroid, low blood sugar, viral illnesses, or other mood disorders.

Seasonal affective disorder is linked to a lack of sunlight. The winter days are shorter, and that itself our circadian rhythm, or internal body clock. Everyone has a specific sensitivity to sunlight, and our bodies take a cue from the morning sunlight each day. In the winter time, the lack of sunlight creates perfect circumstances to experience SAD.

Light therapy, by definition, gives you a healthy supply of what you lack in winter months, often leading to SAD. But light therapy is much more than that. Light therapy’s uses and benefits are many, so while treating SAD, you could also be treating other problems you may not even know of – it’s like killing multiple birds with one stone, and that stone happens to be safe, non-invasive, and non-pharmaceutical.

Light therapy mimics the positive effects produced by exposure to the sun. It reproduces the effects the sun provides us with, and can solve numerous symptoms of SAD through the use of ultraviolet rays. You may be wondering if red light therapy is safe for skin: yes, it is entirely safe. Specifically, with Kayian's light therapy devices, which are FDA-approved and MDA-certified.

With light therapy, you're able to stimulate your cells into rejuvenation. The light works directly at the cellular level and triggers the reproduction of ATP, the fuel our system needs to function properly. 

Light therapy helps with SAD by causing our brain to believe it's getting more sunlight. Even though the light is fabricated, it's still light. We still reap all of the benefits as we do from sun exposure. Melatonin and serotonin are what affects the impact; they too, are triggered by our light therapy devices, which is what battles SAD. 

The scientific evidence on light therapy and SAD says that even within the first hour, you may experience positive results. With daily use of light therapy, thousands of people have overcome the debilitating symptoms of SAD and other disorders, and now even college students can turn to the holistic treatment to replenish the light they’re lacking.

“The benefit of having a beard is protection, as well as aesthetics,” says Dave Harvey, M.D. “It's good protection against wind, chafing, and traumatic injury. It’s also a trend, so we see a lot of men with some form of facial hair.”

The Health Benefits of Beards

Beards can:

  • Protect skin from sun damage. Beards can help protect the skin from harmful UV rays, though the degree of protection may depend on hair density and thickness. “You’re going to have some protection because hair is a reflective medium,” says Dr. Harvey. “Even though some UV rays get through, there is some scattering of the light, and that’s how it helps protect against sun damage.”
  • Keep you warm. Beards can add a layer of protection to your chin and neck, thus keeping you warm in colder weather. The longer and fuller the beard, the better it will insulate your face.
  • Make you feel more attractive. A study conducted by the Official Journal of the Human Behavior and Evolution Society found that men with a moderately full beard are most attractive. Men with full beards may be perceived as better fathers who could protect and invest in their children. “Men with beards have a powerful look,” says Dr. Harvey. “And that’s an attractive thing.”

Common Problems for Beard Growers

Growing a beard is not always easy. And if your beard is not properly cared for, it can become a harbinger for bacteria.

“If you don’t clean your beard well, and you let it just do its own thing, sometimes you can accumulate yeast and get dandruff within the beard,” says Dr. Harvey. “With that, you’ll get a reactive scaling on the face and flaking like you would with dandruff. So those patients need to be put on antifungal shampoo.”

Beard growers also face the challenge of ingrown follicles that result in bumps known as acne keloidalis.

“Some men will get a raised scarring type of bump called an acne keloidalis of the neck,” he says. “So we offer them topical antibiotics or Retin A for those particular reasons.”

Low-Level Laser Therapy for Beards

Low-level laser therapy (LLLT) is an FDA-approved treatment using laser light energy to circulate blood flow to hair follicles. Laser therapy for hair growth can be used to stop hair loss in men and women. The non-invasive lasers stimulate hair follicles to induce regrowth, resulting in a thicker beard in several weeks of treatments.

Laser hair therapy is also called red light therapy. The process irradiates photons in skin tissue, resulting in photons being absorbed into weaker hair follicles and promoting hair growth.

How Successful Is Laser Hair Restoration?

Laser treatment for hair loss works because photons amp up circulation and stimulation, which brings back hair follicles that may have died off.

Clinical Study

Laser hair restoration therapy is continuing to develop. Still, the National Institutes of Health has conducted multiple studies on laser hair growth therapy to see if it works for those with alopecia and male pattern baldness.

The NIH study used a controlled clinical trial that found laser hair therapy works for men and women, and it’s safe.

Another study from 2013 included male participants aged 18 to 48. The result of laser hair therapy treatment included a 39 percent increase in hair growth for participants over four months.

However, laser therapy is just one piece of the puzzle. Many factors contribute to repeated hair loss, including:

  • Age.
  • Genetics.
  • Medical conditions like diabetes and lupus.
  • Hormones.
  • Poor diet.
  • Side effects of medications, such as chemotherapy.
  • Stress.

How Long Does Laser Hair Therapy Take To Work?

From your first treatment, it can take several weeks to see a noticeable difference. This is because red light therapy for hair loss must be administered multiple times over 4 to 6 weeks to begin working.

If you don’t see any growth after 90 days, it’s probably unlikely you’ll regrow hair with this method. You should consult your doctor about the growth cycle and see how long it will take.

One Tree Planted x Kaiyan: A Partnership for a Greener Future

With all of the environmental concerns surrounding pollution and climate change, the world is at great uncertainty. The list of issues with respect to the way we treat our environment is an increasingly long one. Eco-systems are being destroyed, making our planet less safely inhabitable for both humans and animals. 

For example, a decade ago, air pollution didn't seem so deadly, yet today, it's one of the most life-threatening problems we face. 

Eco-systems often cause and create their microclimates, and with their disappearance, the earth's climate is corrupted. Draught is more frequent around the world and the infamous temperature rise and warming of the climate. Our carbon footprint can and should be reduced, and even though it may seem difficult, the changes have to start somewhere.

The importance of companies taking charge lies in their global reach. Businesses worldwide are capable of spreading information globally, drawing attention to important matters that could make a vital change in the world. Companies staying aware and taking responsibility for their impact on the environment make us more aware of our responsibility. 

So, what’s our story? 

At Kaiyan we've been producing the highest quality light therapy devices for 15 years. Our products are MDA-certified and FDA-approved. First and foremost, our products are designed to improve our customers' well-being, not through gimmicks but science-backed LED therapy devices. 

Our products focus on bringing back balance into the body, inside and out—the natural way. The best part is light therapy is a non-invasive and long-term solution of helping with various health problems, from the inside out. The type of light therapy colors used offers a wide range of benefits. 

With skin, it works by smoothing it out and helping in the general glowing appearance. With light therapy, collagen production increases, which results in fewer wrinkles and fine lines. It helps with wound healing and scars and also with more serious skin problems such as eczema and psoriasis. 

But light therapy capabilities go beyond skin deep. Light therapy also helps with mental health issues such as depression and sleep disorders. Working the way it does, from within, means it penetrates directly into our cells. This way, our cells are rejuvenated, and ATP production boosted. By better cell reproduction, we have a better and healthier organism. 

Many people also struggle with vitamin D deficiency, which causes muscle and bone pains, alongside extreme fatigue. Vitamin d deficiency light therapy works by substituting the Sun. Where it lacks sunshine, our LED light therapy device helps create serotonin and melanin we’d usually get if there were no lack. 

So the health benefits of color light therapy are many, ranging from surface level problems such as skincare to deeper lever problems such as mental health disorders. Working at the cellular level helps our brain's chemical process, creating a better and healthier balance for our bodies. 

Though our focus is improving the human body, we also want to do our part to protect our planet. Kaiyan’s mission is to help with the environment by bringing balance and wellness to the world. This means creating the best and most effective light therapy products while ensuring the environment is kept in mind. 

Saving the Planet One Tree at a Time

One Tree Planted is a non-profit organization working as an environmental charity. Their mission is to help the environment, and they do so by helping us and providing an easier way for individuals or businesses to get involved. One Tree Planted takes online donations and uses the funds to invest in reforestation.

The organization started its project in 2014, and by 2020 the numbers increased from 50 thousand to 15 million. Creating a healthier climate and better world has never been easier. One Tree Planted puts effort into protecting biodiversity and natural habitats. They work with partners in the Americas, Asia, and Africa. Apart from creating new forests, they also restore forests damaged from floods or fires.  

With each Kaiyan manufacturing order, our clients are given the opportunity to select a location for a tree to be planted in their name. Trees help create more oxygen in the atmosphere, and even purify our air. It's an incredibly worthwhile, and impactful opportunity to do something for our mother earth. At the end of the day, sustainability is something we at Kaiyan are working towards passionately, and with our One Tree Planted Partnership, we're able to get our incredible clients involved in bettering the planet, as well.

Wellness Gurus: Who's Turning to Light Therapy for Full-Body Treatment

Light therapy has many benefits, working from the inside, out. It not only helps with our appearance but also internal wellness — because who said beauty's just skin deep? 

Many people find themselves turning to this new form of treatment since it's non-invasive and comes with long-term positive effects — something most people aren't used to hearing. 

While outwardly, the skin smooths out, pores are reduced, wrinkles diminished, and collagen restored. Inwardly, light therapy works directly with our cells, generating an increase of ATP, the energy that fuels us. 

LED Light Therapy uses color wavelengths of visible light, each with specific skin benefits. Due to sun damage, aging, skin disorders, healthy skin cells are compromised and have a more difficult time renewing themselves normally.

But why are wellness gurus going crazy for light therapy? 

Light therapy is not that new; however, it's been gaining popularity due to its benefits, especially in the wellness industry. While everyone is eager to look younger, going under the knife is very invasive. Light therapy is not only effective and easy to use; it's non-invasive. The device needed for light therapy is usually a lamp or light therapy box. 

Is light therapy good for skin? Absolutely. And one of the best things next to the long-term effects is that light therapy can be used as laser light therapy at home. This is the most comfortable way of having the benefits of light therapy. Many celebrities themselves are opting for this route as opposed to invasive treatments.

Light is used as a source of energy, and our skin soaks it up, turning it into ATP (our life fuel). Cells reproducing faster and more efficiently brings the repair and rejuvenation of damaged cells, or, in the case of treating acne, kill bacteria. This stimulates the production of collagen and elastin, boosts circulation, and accelerates tissue repair. You simply lie underneath a light screen during the treatment while the LED light device.

What can light therapy be used for you may be wondering? It isn't only beneficial for your skin; it works directly within our cells, accelerating ATP production. This makes it helpful with overall health, physical and mental. Light exposure has also been linked to being a trigger of serotonin, the way natural light does as well. Not only does it trigger serotonin, but also melatonin, which helps regulate your sleep cycle. 

Luckily, instead of having to go to a doctor for your treatments, you have your own LED light therapy mask or device in the comfort of your home. Allowing wellness gurus and everyday people to enjoy the benefits of red light therapy. 

Light therapy devices work not only the face but as a full body treatment that can help with muscle tension and fascia. Fascia is the connecting tissue that holds every organ, blood vessel, bone, nerve fiber, and muscle in place.

Gwyneth Paltrow even explores on goop.com the many different appealing sides to it. “Light acts as a mild stressor on the body in a dose-dependent manner. We always consider stress to be a bad thing, but at low levels, stress can be good for us. It conditions our tissues and stimulates endogenous protective responses that prime us for either existing or future insult.”

Kourtney Kardashian has taken her LED light therapy mask to the public as well, promoting the device and its benefits. She enjoys both red and blue light treatments, often posting her with her at-home mask. She’s mentioned retinol use alongside the regular treatments, and other skin rejuvenating products. 

But more and more celebrities and wellness gurus are turning to light therapy for a full body treatment. Jessica Alba, alongside celebrities including Emma Stone, Chrissy Teigen, Lena Dunham, Kelly Rowland, and Real Housewives of New York City’s Carole Radziwill, have openly discussed red light therapy treatment. 

Many top skincare and wellness brands are turning to Kaiyan for their red light therapy device production. And though we produce devices that are incredibly effective, our devices are also MDA-certified and FDA-approved, giving you security in knowing your devices not only are effective but are safe. 

SAD - Seasonal Affective Disorder 101

The first formal description of Seasonal Affective Disorder (SAD), the most well-known psychiatric condition associated with seasonality in humans, was introduced in the mid-1980s by Rosenthal, who described a group of 29 patients living in a temperate climate who experienced depressive episodes characterized by hypersomnia, hyperphagia, and weight gain in the fall or winter, and whose symptoms remitted by the next spring or summer.

SAD was incorporated into the Diagnostic and Statistical Manual (DSM) of Mental Disorders III-R when “seasonal pattern” was introduced as a specifier for Major Depression and Bipolar Disorders. Subsequent revision in DSM-IV described SAD as “a regular temporal relationship between the onset of Major Depressive Episodes in Bipolar I (BPI) or Bipolar II (BPII) Disorder or Major Depressive Disorder (MDD), recurrent, and a particular time of the year.”

Today, SAD, or MDD with seasonal pattern, is defined as recurrent episodes of major depression that meet the following criteria: at least two consecutive years where the onset and offset of depressive symptoms occur at characteristic times with no non-seasonal episodes, a temporal relationship between onset of symptoms and time of year, a temporal relationship between remission of symptoms and time of year, and an outnumbering of seasonal compared to non-seasonal episodes throughout the lifetime of the patient.

Pathophysiology of SAD

To date, the pathophysiology of SAD is unclear. Early research into the mechanism of SAD focused on day length or photoperiod. This hypothesis posited that shorter days in winter, possibly mediated by a longer duration of nocturnal melatonin secretion, leads to depressed mood in susceptible individuals. To date, there is little data to support this hypothesis. Furthermore, given that bright light in the evening has not been as effective as that given in the morning, it now seems unlikely that the photoperiod is the underlying pathological mechanism of SAD.

Although some animal studies have implicated a direct effect of light on the midbrain (Miller, Miller, Obermeyer, Behan, & Benca, 1999; Miller, Obermeyer, Behan, & Benca, 1998), the most prominent hypothesis driving human studies involves disruption of circadian rhythms. Research on the role of serotonin is also active.

Circadian Rhythm

A circadian rhythm refers to the approximately 24-hour cycle of physiological processes present in humans and other animals. This cycle is governed via clock gene expression by the suprachiasmatic nucleus (SCN), the master pacemaker located within the anterior hypothalamus. Though the SCN endogenously generates circadian oscillations, SCN endogenously generates circadian oscillations, and they need to be entrained to the 24-hour day by external cues. Light exposure is the most important synchronizing agent of endogenous circadian rhythms.

Downstream of the SCN, a collection of systemically active neurohumoral networks transduce circadian information to the rest of the body. For instance, via projections to the hypothalamus's paraventricular nucleus, the activation of the SCN leads to autonomic changes, including cardiovascular modulation, and together the central, peripheral, and autonomic nervous systems collaborate to affect systemic changes. Thus, the SCN receives information about the external day-night cycle directly through retinofugal pathways and indirectly through neuromodulatory signaling. Circadian information is then relayed systemically through neurohumoral networks.

The current primary hypothesis for the pathophysiology of SAD, known as the “phase-shift hypothesis,” posits that there is an optimal relationship in the alignment of the sleep-wake cycle and the endogenous circadian rhythm. During the fall and winter, as day length shortens, the circadian rhythm begins to drift later concerning clock time and the sleep-wake cycle. This phase delay is hypothesized to bring about mood symptoms. A pulse of morning bright light generates a circadian phase advance, which is thought to correct the discordance between sleep and circadian phase, thereby ameliorating depressive symptoms. However, the phase-shift hypothesis would predict that the amount of phase correction required for each patient would depend on an individual’s PAD, which has not yet been proven.

Serotonin

Several studies have also proposed that serotonin is implicated in the pathophysiology of SAD, as selective serotonin reuptake inhibitors (SSRIs) appear to be effective in the treatment of SAD. Supporting this hypothesis, one study used Positron Emission Tomography (PET) imaging to look at binding probability at synaptic serotonin transporters in 88 normal individuals living in the temperate climate of Toronto, Canada (Praschak-Rieder, Willeit, Wilson, Houle, & Meyer, 2008). The binding probability was increased during fall and winter compared to warmer months, thus eliciting an inverse correlation between binding potential and sunlight durationsunlight duration. Of note, the largest difference in transporter binding was found in the mesencephalon, a finding consistent with animal studies demonstrating the importance of direct effects of light to the midbrain on behavior. If increased transporter activity indicated greater reuptake of serotonin during the fall/winter, and if this resulted in a lower density of cleft serotonin, then the seasonal variation in transporter activity (i.e., higher transporter efficiency in the winter) would seem to leave susceptible individuals particularly prone to mood symptoms during the darker seasons. Moreover, following BLT and during periods of remission in the summer months, the synaptic transporter activity was shown to be reduced to control levels in these patients.

Eating Disorders

BLT has also been investigated to a lesser extent in eating disorders. Because binge eating episodes have been observed to increase in fall and winter in some patients, BLT has been examined as a treatment modality for anorexia nervosa (AN) and bulimia nervosa (BN). Thus, BLT's effects on patients with eating disorders remain enigmatic. Additional studies, including larger, randomized, blinded, and controlled trials, are needed to elucidate further the role of BLT in treating this patient population. Further research might also determine whether BLT would be a useful treatment in Binge-Eating Disorder, a diagnosis new to DSM-5.

Adult ADHD

Additionally, BLT has been studied in the context of adult Attention-Deficit/Hyperactivity Disorder (ADHD), where, in addition to normal ADHD symptoms, patients often have depressed mood and difficulties falling asleep, awakening on time, and maintaining arousal (Brown & McMullen, 2001). These symptoms are indicative of a possible delay in the circadian rhythm. A case report of symptom improvement following BLT in a child with ADHD who displayed signs of delayed sleep phase also supports the idea that BLT may be useful in treating symptoms of ADHD (Gruber, Grizenko, & Joober, 2007). Whether the pathways that subserve the improvement of mood symptoms in response to BLT are the same pathways that underlie the seemingly beneficial effects of BLT in ADHD remains to be studied. While these results are promising, further studies, preferably in randomized, blinded, and controlled studies will need to be performed.

Finally

A significant immediate reduction of depression scores with light treatment can be identified after 20 minutes and reaches the maximum at 40 minutes, with no additional benefit at 60 minutes. The rate of change is steepest during the first 20 minutes of light as compared with longer intervals. Comparing the clinical impact of these durations of administration may yield different results when measured after several daily sessions. The overnight effect on circadian rhythms and sleep was not assessed in our study and is thought to impact mood regulation in SAD. Larger, prospective, controlled, and hypothesis-driven studies in more naturalistic conditions would be desirable to replicate our study results and our study results and analyze the temporal dynamic of the persistence of the immediate mood-improvement effects. Besides, in larger samples, one could define early responders and nonresponders, analyze genetic (e.g., melanopsin related genes), demographic (children, adolescents, adults, elderly, gender), physiological (e.g., pupillary responses), and clinical (e.g., abundant atypical symptoms) predictors for early response. If proven effective and efficacious, shorter exposures to bright light could become a feasible and broadly employed intervention for immediate mood improvement as an early step on the road toward full antidepressant response and remission.

Dreaming of Light Therapy

Light therapy is beneficial for more than just one problem. Rather, it’s an all-in-one health and wellness treatment. It helps with skincare issues ranging from acne to wrinkles to eczema by supporting the mitochondria, which in return provokes better cell production within the body and targeted areas. 

But another thing light therapy is proving to be powerful with is sleep. Sleeping disorders are more frequent than ever, with many people experiencing sleep disorders and, if not full disorder, struggle with achieving restful sleep. 

Stress and anxiety build up through the day, and our addiction to our devices greatly disturbs our sleeping habits. However, a good night’s sleep is actually one of the most important things to maintain if you want optimal health.

While there are many types of sleep disorders—insomnia, sleep apnea, restless legs syndrome (RLS), and narcolepsy—bright light therapy has proven to help reduce many of these conditions. In addition, its effects are also being studied on how they can help with Parkinson’s disease. 

Sleep onset insomnia is one of the things light therapy can effectively treat. Insomnia is the inability to fall asleep at a normal time. Though there are various reasons for insomnia, one problem stems from the advanced or delayed circadian rhythms.

There’s also advanced sleep phase disorder when you tend to feel sleepy in the late afternoon or early evening. Bedtime typically happens between 6 p.m. and 9 p.m. Early bedtime means you often wake up between 2 a.m. and 5 a.m. Light therapy here can help reset your internal clock in the early evening hours.

With delayed sleep phase disorder, you tend to stay up all night or at least a few hours, often past midnight. As a result, you also tend to wake up later in the morning, having lost a good chunk of your day. In this instance, light therapy in the morning, right after you’ve woken up, helps to advance your internal clock and makes you feel sleepy earlier in the evening, helping to adjust to a normal sleeping pattern.

And yet, light therapy treatment is proving to be the perfect solution.

In 2012, Light therapy was studied and found to be an effective nonpharmacological and non-invasive way of treating sleep disorders and improving sleep quality among elite female basketball players. Each participant within the research received14-30 minute light therapy sessions once every night for 14 nights in a row.

Research also showed improved melatonin levels among basketball players, and melatonin is a hormone that promotes sleep. Players in return experienced improved endurance performance. 

In later studies as well, light therapy has proved itself to be very effective. In 2013, a Taiwanese study looked at participants and their electroencephalography (EEG), which means they examined their electrical brain activity. They checked before, during, and after the light therapy simulation. The research suggested that light therapy is beneficial in helping people with sleep disorders. But these are the only studies that show the effectiveness of light therapy.

A study on the cognitive function of people with traumatic brain injury discovered that light therapy helped those people with their cognitive function. Light therapy helped decrease episodes of post-traumatic stress disorder (PTSD). Participants also reported better sleep during the study. 

New research from the University of Arizona Health Sciences discovered that with light therapy, people with migraines have a better chance of improving their sleep, plus act as a preventative measure for future migraines. Patients who were submitted to the research experienced better sleep and fewer headaches with light therapy.

Our minds have been occupied with a lot, with the pandemic, with people experiencing more hardships than before. Even if they’ve gotten used to it, the way of living has drastically changed. It’s no surprise that our sleep has also been affected by this. It’s reported that having bad dreams due to the ongoing pandemic isn’t anything too surprising nor impossible. 

Growing evidence suggests that light therapy can help us improve the ability to fall asleep, remain asleep and get a good night’s all in one. In times when our dreams and sleep are invaded by negative feelings related to any upsetting and unsettling occurrence in our life, light therapy can help us ease our daily stressors and might help us avoid sleep-disturbing dreams.

That said, you want the right light therapy device to help you improve your sleep. Kayian medical produces MDA-certified and FDA-approved light therapy devices to ensure you get the most out of light therapy. 

Red Light Therapy & Vitamin D Production


Aside from nutrition and water, we need vitamin D to survive. In fact, almost every living creature on earth needs vitamin D to survive—it’s a crucial vitamin for all species. Vitamin D helps regulate the amount of calcium and phosphate in the body, which are responsible for the health of our muscles, bones, and teeth. 

In addition, Vitamin D fights disease, reduces depression, and aids in weight loss. When we lack vitamin D in our bodies, it can lead to a loss of bone density, which plays a significant role in osteoporosis and fractures. 

Naturally, a lot of our nutrients come from food; however, vitamin D is also produced in our skin’s response to sunlight. It wasn’t given the nickname the “sunshine vitamin” for nothing. Sitting outside (with sunscreen on, of course) can boost vitamin D levels in the body. By doing so, it can regulate moods and reduce depression. 

In one study, scientists found that people with depression who received vitamin D supplements improved their depression symptoms. While vitamin D supplements are an option, it can take between three to four months until you start to notice improvements. That’s a long time to wait, especially if you’re struggling with depression. However, there is a way to increase vitamin D production without having to wait months to improve. 

As we’ve discussed above, you don’t need sunlight for vitamin D production. You can either take vitamin D3 as a supplement, taking months to work, or through red light therapy, receiving quick results. So, how can you increase vitamin D through red light therapy? 

Before we get into it, it’s important to know that contrary to popular belief, not all forms of light can increase vitamin D in the body. The type of light used in light therapy devices is crucial. Natural sunlight contains both “red” and “infrared” light. These are the two forms of light that are needed in light therapy devices to increase vitamin D production in the body. 

Without red and infrared light, nothing is going to happen. These two forms of light have their own unique benefits to the human body. 

In one study published in Scientific Reports, it found that LED lights are more efficient than sunlight at producing vitamin D3 in skin samples. Tyler Kalajian and his team found that skin samples exposed to LED for 0.52 minutes produced more than twice as much vitamin D3 than samples exposed to 32.5 minutes of sunlight.

Another study focused on cystic fibrosis and short bowel syndrome patients who are unable to absorb vitamin D3 through food. The study used UV light to test whether it would affect vitamin D3 production in the patients’ bodies. It was found that the UV lamp emitted UV radiation similar to sunlight, producing Vitamin D3 in the skin. 

What’s amazing about these studies is that aside from showing light therapy’s effectiveness in producing vitamin D, they also prove light therapy is an excellent source of vitamin D during the winter season. 

During the winter, many people suffer from SAD (Seasonal Affective Disorder) and are unable to find a vitamin D source. But, through red light therapy, users are able to increase vitamin D production regardless of whether there’s sun outside or not. Instead of using antidepressants or slow-moving vitamin D supplements, red light therapy is a fast-acting alternative. 

With Kayian Medical’s MDA-certified and FDA-approved red light therapy devices, users can get their lives back and be in control of their health with effective and quick light therapy treatment.


Creating Your Custom LED Mask

When we talk about skincare, we usually don’t think about customizing skincare products. The options available on the market are produced for the masses rather than for the individual. Many people with multiple skin issues struggle to find skincare products that truly speaks to their needs. However, light therapy masks can be customized to fit the individual customer’s needs.

If you’re working in the skincare industry, light therapy devices are a revolutionary step forward, as you’ll be able to provide your customers with a unique light therapy mask.

But what’s the process of creating a custom light therapy mask? Here are the six steps you need to consider when developing a customized light therapy mask.

The Six Steps to Create Your Custom Led Mask

While going through these six steps, keep your vision of your mask in mind. This will help you answer some of the questions that are going to be asked below.

What’s your Goal?

It would help if you determined your product’s goals. Who are your clients? What are their unique skincare challenges? By understanding the basics, you’ll help your company determine the right strategy when creating your customized product. Light therapy masks can be made using different LED colors for a full range of beauty treatments, including acne reduction, anti-aging treatment, and collagen production.

What Material will you Use?

You need to select the right material. Facial masks can be made from a variety of materials, each with its own advantages and versatility. There are three types of light therapy masks to consider: flexible, semi-hard, and hard.

Flexible allows users to wear it while doing their daily activities. The patented air cushions and emitting SMD LEDs are ideal for indoor and daily skincare. Semi-hard masks are for professional use and have a hard shell, while soft inside. Hard masks are powerful facial masks for professional use and come with selectable light area options. They offer a deeper light therapy experience for clients.

What Kind of Shape will your Mask be in?

Light therapy masks don’t have to come in a traditional one-size-fits-all design. Depending on your target market, you’ll be able to choose where the placement for the cheeks, forehead, and eyes will be on the mask. This gives you more control over how the mask will fit on your client’s face.

What Areas Will your Mask Treat?

A traditional mask will cover the full face. However, you may not necessarily want your mask to provide full coverage. Consider the areas of the face you’d like to treat, as you may only want to create a mask for a specific target area.

Apply for a Prototype

You’ve answered all the questions above and have a vision of how you want your mask to look. From here, we help you take your vision and use our creativity and 14 years of experience in the industry to create a mask that fits your goals.

Launch & Listen

Now that the product is created, it’s time to launch it. Before the launch, we produce pre-pilot quantities that allow us to fine-tune our devices and ensure high-quality from start to finish.

Creating a light therapy facial mask is one thing, but you want to make sure it’s achieving your goals and making your customers happy. Once your product is launched, it’s crucial to monitor product performance and listen to customer feedback.

Naturally, you don’t want your light therapy mask to be like all the others on the market. Our masks are MDA-certified and FDA-approved light therapy devices, ensuring you medical-grade quality devices for your business.


Insomnia & the Dark Side of the Blue Light

Although it is environmentally friendly, blue light can affect your sleep and potentially cause disease. Until the advent of artificial lighting, the sun was the major lighting source, and people spent their evenings in (relative) darkness. Now, in much of the world, evenings are illuminated, and we take our easy access to all those lumens pretty much for granted.

But we may be paying the price for basking in all that light. At night, light throws the body’s biological clock — the circadian rhythm — out of whack. Sleep suffers. Worse, research shows that it may contribute to the causation of cancer, diabetes, heart disease, and obesity.

What is Blue Light?

Not all colors of light have the same effect. Blue wavelengths — which are beneficial during daylight hours because they boost attention, reaction times, and mood — seem to be the most disruptive at night. And the proliferation of electronics with screens and energy-efficient lighting increases our exposure to blue wavelengths, especially after sundown.

Light and Sleep

Everyone has slightly different circadian rhythms, but the average length is 24 and one-quarter hours. The circadian rhythm of people who stay up late is slightly longer, while earlier birds' rhythms fall short of 24 hours. Dr. Charles Czeisler of Harvard Medical School showed, in 1981, that daylight keeps a person’s internal clock aligned with the environment.

Is Nighttime Light Exposure Bad?

Some studies suggest a link between exposure to light at night, such as working the night shift, diabetes, heart disease, and obesity. That’s not proof that nighttime light exposure causes these conditions, nor is it clear why it could be bad for us.

A Harvard study shed a little bit of light on the possible connection to diabetes and possibly obesity. The researchers put 10 people on a schedule that gradually shifted the timing of their circadian rhythms. Their blood sugar levels increased, throwing them into a prediabetic state, and leptin levels, a hormone that leaves people feeling full after a meal, went down.

Exposure to light suppresses the secretion of melatonin, a hormone that influences circadian rhythms. Even dim light can interfere with a person’s circadian rhythm and melatonin secretion. A mere eight lux — a level of brightness exceeded by most table lamps and about twice that of a night light — effects, notes Stephen Lockley, a Harvard sleep researcher. Light at night is part of the reason so many people don’t get enough sleep, says Lockley, and researchers have linked short sleep to increased risk for depression, as well as diabetes and cardiovascular problems.

Effects of Blue Light and Sleep

While light of any kind can suppress melatonin's secretion, blue light at night does so more powerfully. Harvard researchers and their colleagues experimented comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours).

In another blue light study, researchers at the University of Toronto compared the melatonin levels of people exposed to bright indoor light wearing blue-light-blocking goggles to people exposed to regular dim light without wearing goggles. The fact that the hormone levels were about the same in the two groups strengthens the hypothesis that blue light is a potent suppressor of melatonin. It also suggests that shift workers and night owls could protect themselves if they wore eyewear that blocks blue light. Inexpensive sunglasses with orange-tinted lenses block blue light, but they also block other colors, so they’re not suitable for use indoors at night. Glasses that block out only blue light can cost up to $80.

LED Blue Light Exposure

If blue light does have adverse health effects, then environmental concerns, and the quest for energy-efficient lighting, could be at odds with personal health. Those curlicue compact fluorescent lightbulbs and LED lights are much more energy-efficient than the old-fashioned incandescent lightbulbs we grew up with. But they also tend to produce more blue light.

The physics of fluorescent lights can’t be changed, but coatings inside the bulbs can produce a warmer, less blue light. LED lights are more efficient than fluorescent lights, but they also produce a fair amount of light in the blue spectrum. Richard Hansler, a light researcher at John Carroll University in Cleveland, notes that ordinary incandescent lights also produce some blue light, although less than most fluorescent lightbulbs.

Protect Yourself from Blue Light at Night
  • Use any of our red light devices for night lights. Red light is less likely to shift circadian rhythm and suppress melatonin.
  • Avoid looking at bright screens beginning two to three hours before bed.
  • If you work a night shift or use many electronic devices at night, consider wearing blue-blocking glasses or installing an app that filters the blue/green wavelength at night.
  • Expose yourself to lots of bright light during the day, which will boost your ability to sleep at night, as well as your mood and alertness during daylight.

Preparing your Skin for Light Therapy

Can I Use Serum With LED Mask?

It is a question that many people have asked — Can I use the serum with LED light therapy?

Our skin is exposed to harsh environmental factors such as sun, wind, cold, and dust daily. These factors tend to attack our immune system causing it to weaken over time.

When this happens, it allows harmful viruses and bacteria to attack our body, leading to acne breakouts and other skin issues such as dark spots and wrinkles. Acne creams are one way of reducing the symptoms associated with this skin condition. However, these can be irritating to your skin, resulting in unwanted side effects such as redness, irritation, and dryness.

The same can also be said for light therapy, which can have its own side effects. Side effects of LED light therapy include itching, burning, and pain. In fact, most users had reported experiencing these side effects when they first started using LED technology. If you were to use any acne medication type, whether prescribed by your doctor or over the counter, the results would depend largely on the person using the medication.

For example, it could take anything from a few days to a few weeks for acne to clear up. Another point to remember is that while certain medications do show better results for some people, they may not work for you at all.

This is because everyone has different skin types, responds differently to treatments, and requires different times to clear away acne completely.

Some people have found success in using LED therapy with a variety of skin creams. However, there is a downside to using this method. LED light therapy does not help remove excess dead skin cells, as some acne medications do. This means that the acne cream will just be left in place and continue to produce side effects for all patients. Besides, side effects can be more severe than a single acne medication dose when used over a long time when used over a long time.

Before you try to use a serum with an LED mask, you should consult with a dermatologist who can advise you on whether or not LED light therapy is right for you. LED light therapy is safe when administered by a certified medical professional. It can be used safely, even if you have sensitive skin, as long as you choose your doctors wisely. Before any treatment is begun, the medical professional will test your skin to determine what type of acne you have. Testing will determine whether your skin is allergic to any light-emitting diodes in the device used.

The last question to answer is, “How effective is Acne treatment with LED Light?” To answer this question, you will need to look at the results you get from the treatment. If you see immediate results after the treatment, it will likely react to the device's light and not the treatment itself.

However, if you don’t see good results after a month of continuous treatment, it is important to determine why the treatment is not working. It may be that you are allergic to any of the ingredients in the product, or it may be that your skin is not receptive to the treatment.

Hydrated Face For LED Mask Results

The serum is good for hydrated face for LED Mask. It can hydrate the skin by absorbing moisture, providing a slight lift to the skin, and removing any oil or makeup that you are using. The serum also contains vitamins and antioxidants that will help fight against free radicals in your body. Free radicals are harmful agents that have been linked with causing cancer.

By fighting against these harmful agents, Serum is good for hydrated face for LED Mask. People who have used Serum have claimed that the hydrated face and LED Mask work very well together. I have also used Serum on my skin, and I must say that the results were really amazing. In fact, I would go on to say that Serum is so good for hydrated face for LED Mask that I will be using it every single night before bed.

If you don’t have much experience making skin look hydrated, this is the forum for you. Let us first examine the ingredient list of Serum.

This product's main ingredients are Hyaluronic Acid, Vitamin C, Retinol A, Alpha Hydroxy Acids, Vitamin E, DMAE, Peptides, and Glycerin, Ferulic Acid, Aloe Vera.

  • AHA kills the bacteria causing acne and helps to get rid of blackheads.
  • Sodium Laureth Sulfate helps in cleaning the skin by getting rid of dead skin cells and excess oil.
  • Salicylic Acid gets rid of pimples and acne scars, and Glycolic Acid is good in treating acne scars.

All of these ingredients are perfectly good for your hydrated face for LED Mask.

  • Now let us move on to how does Serum works to get rid of the facial puffiness.
  • When you are applying Serum on your hydrated face for LED Mask, you are putting on a layer of serum to the surface of your face.
  • As the serum gets applied, it works its way down into your skin and starts working as a moisturizer.
  • This is why this particular product is top-rated as it works as a good moisturizer without over-drying the skin.
How to Prepare Your Skin For a Red Light Therapy Session?

There are different methods used to prepare your skin, but essentially they all work in the same way: removing all the oil and dirt from the skin and then cleaning it. When I talk about cleansing, I’m talking about daily skincare maintenance products. If you want to know how to prepare your skin for a red light therapy session, this is the part that you need to read.

Most people have no idea how their skin looks like, so when they go into the doctor’s office and they've asked if they’ve had a photodynamic therapy or a laser treatment, they’re not aware of what treatment they might have received.

  • The skin absorbs red light from the sun, and in return, it produces negative ions.
  • These are similar to the particles produced by an activated oxygen generator (you know those things at the gym).
  • During photodynamic therapy, the skin cells absorb the energy from the lasers' red light, which causes the release of more negative ions, which then penetrate deeper into the skin.
  • They’re working like the “batteries” on your car — they give the batteries extra power and allow the car to run much longer.
  • If you want to learn how to prepare your skin for a red light therapy session, you must remove all the grime from your face and neck before the session.
  • Cleansing is one of the most important steps to remember in preparation.
How to Prepare Your Skin for Red Light Therapy Session by Using Non-Dry Cleanser

You might need more than just a good cleanser when trying to prepare your skin for red light therapy. Your cleanser is your friend when you are trying to remove all the dirt and excess oil from your face, but what if your cleanser is too harsh on your skin? If you have dry skin, using a cleanser containing too harsh ingredients may cause dryness, making it harder for you to remove those excess oils from your face.

When you prepare your skin for red light therapy session using the non-drying cleanser, make sure that you would be using a toner with antioxidants and anti-inflammatory ingredients to increase the collagen level the skin.

This will help keep your skin healthy and younger-looking.

Caution: Lotion and Moisturizers For LED Masks Are Not Recommended

The use of moisturizers and lotions is not recommended for LED masks because it will damage your skin. There are also cases wherein people who used such products ended up suffering from adverse effects.

The ingredients in these products may be too strong for the skin to be able to absorb.

You can prevent this by using only non-comedogenic lotions and moisturizers for LED masks.

  • This way, the product is less likely to irritate your skin. In addition to that, you can also use other types of products designed for sensitive or dry skins to use on your face during the event's preparation.
  • However, there are cases wherein people who have been using such moisturizers and lotions as part of their LED facial make-up mask ended up suffering from adverse effects.
  • In these cases, the products were not properly applied to the skin, and the amount that was applied was also insufficient.
  • Because the skin did not get sufficient moisture, the cells underneath the skin's surface could not repair themselves properly.
  • This will result in damaged skin, which will cause more breakouts than before.

Aside from lotion and moisturizers, it would help if you also stayed away from mineral oil, alcohol, and preservatives. These ingredients are not good for your skin, as they can cause dryness and irritation. It would help if you also stayed away from using creams and lotions with fragrance, which can only irritate your skin even more. Instead, look for serums.

If you want to have a glowing complexion without enduring any adverse effects, use a good quality face serum.

Prepare Your Skin For Red Light Therapy by Removing Sunscreen

You probably have heard that it is unsafe to use the sun’s UV rays at home, especially if you use a tanning lotion or a self-tanning lotion. But did you know that it is also not safe to use self-tanning products like tan accelerators and sunless tanning pills to prepare your skin for red light therapy sessions?

This defeats the purpose of using red light therapy, and you must remove sunscreen so that your face and skin are completely ready to receive the red light therapy. This is because self-tanning products contain ingredients that can affect the skin in adverse ways and block the beneficial deep penetrating infrared wavelength from 650nm to 850nm.

How to Prepare Your Skin For Red Light Therapy by Removing Makeup

If you have chosen to have laser acne treatment and you are wondering how to prepare your skin for the red light therapy, you will want to take a moment to learn how red light therapy works before getting started.

Before your session begins, you will be given a short amount of time to get ready for the procedure. This is because your skin needs to be very clean and free of any makeup. Your skin needs to be completely dry before the procedure can begin.

If there is any moisturizer on your skin when you arrive for your appointment, you will have to remove it before your treatment.

Your doctor will ask you several questions about your skin during your appointment, including what type of skin you have and whether or not you have any allergies. During this time, they will also determine if you are a good candidate for the procedure. If you are cleared for the procedure, your skin will be exposed to an intense red light level. This is one of the most effective ways to get rid of acne, and it can also help prevent scars and aging from occurring on your face.

The amount of time that it takes to get your skin prepared for red light therapy varies. In most cases, it is normal to have it take from fifteen to thirty minutes to prepare your skin for the procedure. You may have to remove any makeup at this time as well.

How to Prepare Your Skin For Red Light Therapy by Exfoliating?

When a patient is getting a therapy session done, they will be required to go to the spa or beauty clinic to be given a facial.

A therapist will then start by cleaning the face thoroughly. After the initial cleaning process, the therapist will apply a chemical that will help exfoliate the skin.

This process can irritate the skin, so it is important to prepare your skin before undergoing this procedure. Some common preparations that people use include salicylic acid, alpha hydroxy acid, retinoids, glycolic acid, and other peel-type products.

The exfoliating procedure aims to help the skin cells shed off dead skin cells and replace them with new cells.

This is why it is important to remove all traces of dead skin cells from your face before undergoing the procedure.

It may seem odd at first, but if you want to get the best results from the procedure, you need to gently exfoliate your skin.

Prepare Your Skin For Red Light Therapy With Moisturizers

When you prepare your skin for red light therapy, you are basically preparing to expose the blue spectrum laser's high intensity and the eventual dry out of the epidermis. The skin must be prepared using a good cream containing Reductase or Salicylic Acid, or by exfoliating the skin using a scrub.

After the procedure, you will need to have topical products applied to your skin to prevent the skin from cracking and peeling. This will also help improve your appearance and prevent future scarring. Removing moisturizers before the therapy can be helpful. This is because the skin’s cells will still be in a dormant state when you receive the treatment; therefore, your skin is not at risk for the dryness associated with moisturizers.

This will also improve your skin's look, especially for those who have undergone this procedure many times. However, you must be youthful if e to remove moisturizers in preparation for the session, as some creams may cause excessive dryness and irritation. Once you are prepared for the session, you can expect the doctor to start the red light therapy by generating a small amount of blue light on your skin's top layer.

The light then travels through the skin, reaching the deepest layers where most of the damage occurs. When the blue light is emitted, it is believed that the cells below the surface of the skin begin to absorb the red light, helping to repair the skin. The increased circulation and nutrient absorption help to rejuvenate your skin, leaving it looking younger and healthier than ever before.


Celebs are Loving Red Light Therapy

When it comes to anti-aging remedies, celebrities are at the forefront of all the latest treatments. For years, Hollywood’s elite have opted for chemically-induced anti-aging treatments, like botox and chemical facial peels. But it looks like Hollywood is stepping away from harsh treatments, particularly with the prominence of clean and holistic beauty trends in recent years. Now, many celebrities have decided to avoid the needles and knives, opting for natural alternatives, instead. 

To prepare for red carpet events, celebrities are flocking to red light therapy for natural, non-invasive anti-aging treatments. Kourtney Kardashian, true to Kardashian form, was relatively early to the red light therapy scene in 2016, when she posted a photo of herself in wearing a red-light mask, touting the many anti-aging benefits of the treatment. Since then, other celebrities such as Kelly Rowland, Emma Stone, and Chrissy Teigen have openly shared their positive experiences using red and blue light facial therapy treatment. 

Some actresses love red light therapy so much, they have their own equipment set-up in their homes. Back in 2018, Olivia Munn told US, "I have my own facial set up, I've got the professional-grade products and machines...But one of the best things is the red and blue light mask."

Red light therapy works by increasing blood flow and oxygen, feeding the cells the necessary energy they need to speed up the cellular process. This process helps decrease inflammation and enhance collagen production, which reduces the appearance of fine lines and wrinkles for tighter and supple skin. 

Jewelry designer and reality T.V. star Kristin Cavallari told US that she keeps away from Botox, but shared that

"I use red light therapy twice a week to prevent lines and wrinkles."

But red light therapy isn’t only for wrinkles and fine lines. Celebrities are expanding the use of red light therapy and using it for their entire bodies. Why? Well, house-friendly red light devices help treat inflammation, joint pain, and muscle soreness. 

Ara Suppiah, M.D., an assistant professor at the University of Central Florida Medical School and an emergency and sports medicine physician, told Us Weekly that “increased energy within a muscle cell allows it to contract harder and repair itself after training.” Since red light increases cell energy, it subsequently helps organs, joints, and muscles to repair themselves and function optimally. 

The list of celebrities who swear by red light therapy continues to grow by the day. Joan Smalls and Bella Hadid visit celeb aesthetician Joanna Czech, who is well-known for using her light treatments on her clients. Riverdale’s Lili Reinhart and Camila Mendes also posted photos from Joanna Vargas’ red light bed.

So, it’s clear that the verdict is in: celebrities are loving red light therapy and the multiple external and internal benefits that come along with it. But do you need to undergo expensive treatments to get a taste of the benefits? Nope! You don’t need to be a celebrity status to enjoy the benefits of red light therapy - even in the comfort of your home. 

Luckily, red light therapy is now available for in-home treatment with Lunas’ FDA and MDA-approved red light therapy devices. By having a red light therapy device in your home, we can all attain our own red-carpet glow without the celebrity price tag.

How to Integrate Light Therapy into your Lifestyle

Our lives are busier than ever, and even though red light therapy sounds like something that could significantly benefit you, we know you might be thinking: “when will I have time for red light therapy?” 

Part of the beauty of red light therapy is that you don't need to change your current routine or lifestyle to enjoy its benefits: if you're someone whose day is busy in front of a desk, you can turn the device on while you work; or if you have easy-going mornings but hectic afternoons, you can enjoy your morning coffee while using our red light therapy device. Or, you can turn on the panel while you’re unwinding with a movie in the evenings –– the options are endless.  

Red light therapy treatment isn’t supposed to take over your day and cause an inconvenience. With an at-home red light therapy device, you make the rules. 

That said, you may be wondering what’s the best time of day to use our red light therapy devices. Well, there are a couple of ways you can integrate red light therapy into your lifestyle. 

There are three main parts of the day: morning, midday, and evening. Though you’re able to use red light therapy any time of the day, some parts of the day can be more effective than others, particularly given your personal health and wellness needs. 

If you’re someone who’s suffering from a sleep disorder, then you may want to focus on using red light therapy during the mornings and evenings. For sleep conditions, using red light therapy around sunrise or sunset are the best times of the day. Why is that? 

It has to do with our biological circadian rhythm, which is the natural internal process that helps regulate your sleep cycle within a 24-hour day. To optimize your circadian rhythm and improve your sleep cycle, you need to sync with your natural sleep rhythm. By doing so, you reduce sleep inertia, insomnia, and other sleep disorders. 

When regulating your circadian cycle, your body releases a hormone called melatonin. This particular hormone is the highest in the blood at night and optimal for helping you fall asleep. When using red light therapy at night, it can help you enhance your natural melatonin production

When using red light therapy in the morning, exposure to light helps stop melatonin production, giving your body a natural energy boost. So, either time of the day––morning or night––can be an incredible time to help your body reset its circadian rhythm. 

You don’t need to schedule off your morning for red light therapy treatment. While you’re eating your breakfast or going through your emails, you simply turn on your red light therapy device and enjoy 10 to 15 minutes of treatment. 

Or, in the evenings when you’re cozied up on the course, washing the dishes, or sitting in bed with a book, turn on your red light therapy panel to help regulate your sleep cycle, mood, and overall health. 

If you can’t manage to use red light therapy in the morning or evening, you can always have a treatment in the afternoon, as well. If you’re dealing with a sleep disorder or seasonal depression, we recommend morning or evening treatment. However, midday treatment will also provide you with a load of benefits, including collagen production, decreasing symptoms of depression, improving sleep disorders, and non-seasonal Bipolar depressive episodes. 

Whatever the condition may be, whether it's a sleeping disorder, skin condition, or depression, Lunas red light therapy devices promote cellular healing from the inside out. What’s important is you find the time of the day that best suits your body’s needs. Everyone is different, so it’s important to find out what works for you and your unique routine and lifestyle.

Red and Blue LED Light on Milk Yield in Dairy Cows

Ruminant nutritionists formulate rations balanced according to the nutritional needs for the ruminant at a specific production level. The assumption being that the cows will eat everything they offered. However, cattle can select their feed, as they put together feed using their tongue and lips. Sorting has been studied most in cows al mixed ration (TMR) since it is often is oftenibitum, allowing cows to pick the feed particles they prefer and still reach the total dry matter (DM) they want. The TMR reports show that the most likely sorting is in favor of the short particles (mostly concentrate) and against the long particles (forages). Therefore, the feeding behavior of the cow modulates the amount of feed she eats, the nutrients she gets, rumen health, and ultimately her milk production.

Several methods have been used to try and reduce feed sorting in dairy cows. Recently, a long day photoperiod has been reported that could lower feed sorting against long particles. Today, Kaiyan provides advanced LED light equipment that is available for commercial use. The LED wavelength can be adjusted to the desired output.

Blue and red wavelength light has attracted interest in dairy barns. The cow eye is not sensitive to a red light, and therefore red light has been suggested as an option for illumination when people need to work with the animals during a time of the day when the cows have night. In humans, blue light is known to cause a carryover effect with increased activity after the light is turned off. If cows respond similarly to blue light, it may be interesting to include blue light in the dairy barns in the late afternoon or evening to stimulate activity during the night. This is of particular interest for automatic milking systems since they require cow activity around the clock. Solutions for dairy barns that include periods of the day with more red or blue LED light are already available on the market, as we now have fixtures of white LED light.

Eating Behavior of Dairy Cows

Encouraging DMI to promote milk production is one of the primary objectives for dairy farmers. The daily eating time, selection, number of meals per day, duration, and number of eating occasions per day are important aspects of feeding behavior.

Factors that Influence Eating Behavior

The environment, age of cattle, teeth condition, feed composition, and processing influence eating behavior. Just like grazing cattle, group-housed cows synchronize their behavior, including eating when kept indoors. The eating behavior of cows is controlled by social interactions, management practices, the environment, and health. Long ago, dairy cows were thought to be crepuscular eaters, motivated by sunrise and sunset timing to go for grazing. However, studies reported that fresh feed delivery timing had more influence on the feeding behavior of dairy cows kept indoors than the time of day. Also, studies found that daily eating time distribution changed following an increase in feed delivery frequency in group-housed dairy cows. The first hour and a half after fresh feed delivery is the period of peak eating activity. Little effect on cow behavior was observed when feed push-ups were done while still some feed in the trough. The feed trough design also affects feeding behavior as cows prefer eating from a feed trough that allows their head to be in a natural grazing position than having their head in an elevated position.

Types of Lights Used in Dairy and the Newly Available Light Sources

Common light sources used in dairy facilities are fluorescent and metal halide lights. During the last few years, LED lights have also become available for animal housing. This is not a new technology; LED light has been used in plant growth research since the mid-1980s but has been costly; hence limited to research only. However, 19 the Haitz’ Law as projected by Steigerwald et al., has come to action, that every decade their cost will decrease by 10 whereas their performance advances by a factor of 20. Now they have become affordable and advanced white LED lights thereby increasing their potential use in animal houses commercially

Advantages of LED Lights

It is possible to adjust the light intensity and spectral composition of LED lights mimicking that of natural day sunrise and sunset, making it possible to control color combinations, e.g., green, blue, and red. A LED light's lifespan is longer than that of fluorescent lights, around 100 000h compared to 8000 h. Furthermore, LEDs thermal output is low, saving energy, containing no mercury, efficient photoelectric conversion, and easy-to-contact to digital control systems making photoperiod management easy, for example, in dairy barns. Due to their long life span, they can decrease production costs as they do not need regular replacement and cuts off labor costs and the often-high risk work task of replacing lights since most barns have very high ceilings. The white LEDs produce light in the wavelength that cows can detect better, with peaks of emission around 460nm and 550.

In one study, ten multiparous pregnant Swedish Red cows in post-peak lactation were used. Cows were housed in a tie-stall barn. They were subjected to a 33-day red or blue LED light treatment during a long day photoperiod with 16 hours day and 8 hours night. Cows were fed silage and concentrate separately. Silage was fed three times a day, ensuring ad libitum intake with 5–10% orts. The concentrate was fed four times per day. Samples of silage were collected thrice a day, and individual orts were collected at the end of the day and the night. Data for eating behavior and milk yield were collected five days before and five days after the treatment period. Eating behavior was determined using the difference in the distribution of fractions of different straw lengths in the silage fed and orts during daytime and night time. A 2-screen Penn State Particle Separator (PSPS) (19mm and 8mm) with a solid bottom pan was used to determine the distribution of large, medium, and short silage fractions. Treatments did not affect total DMI. Overall, cows sorted for the large fractions against the medium and short fractions. During the LED period, there was a difference (P<0.001) in sorting between Red and Blue cows during the daytime. Cows on the Red LED light are sorted for the short fractions during the daytime. Blue cows showed different sorting (P<0.05) during day and night. Their sorting for the large fractions was more pronounced during daytime than night. Milk yield did not change during the trial and did not differ between the Red and Blue groups. In conclusion, sorting activity was greater during the daytime in the LED period, which could have been influenced by the LED light. Interestingly cows seem to have better vision in red than blue LED light. Furthermore, it also possible that the LED light maintains milk yield since no change was observed during the four-week trial in post-peak lactation.

Bear, Wolf, Lion or Dolphin: How Understanding your Sleep Type Will Change your Life

Sleep is big business these days — one in three people are believed to experience sleep deprivation — and everyone is keen to rely on the latest fashionable theory.

For years, sleep cycles were divided into two categories. People who enjoy mornings were known as “early birds.” And those of us who prefer staying up late were labeled “night owls.”

Well, step-aside birds. Mammals are the new name of the game. That’s right; scientists now believe there are four ways to classify sleep/wake cycles. In the science world, these classifications are known as chronotypes.

Chronotypes describe the periods when your body wants to sleep and when it wants to be awake. And to make it easier, the chronotype categories are named after animals. Our natural sleep tendencies are now categorized as bear, wolf, lion, and dolphin.

It is crucial to understand your animal chronotype. Once you do, you can start to schedule your life around your body’s natural cycles. Kaiyan Medical suggests that this may help you sleep better and feel more productive at work.

Two Animals are not Enough

People have different circadian rhythms. That’s just a fact of life.

Science shows that:

“The human circadian system actively synchronizes to the 24-h day via environmental signals of light and darkness.”

Circadian? A 24-hour cycle. It’s your body clock. Sleep psychologists reckon they can determine our natural sleeping patterns. By understanding our own, we can have a happier, more productive life.

Now, Chronotype is a term that describes a person’s natural rhythm. And it doesn’t only relate to sleep. Chronotypes influence all primal instincts.

Author Michael Breus, Ph.D., recently suggested that there are 4 natural chronotypes. And he named these after 4 animals that follow similar sleep/wake patterns. So, say goodbye to night owls and early birds. Wolves, lions, bears, and dolphins are the new circadian rhythm mascots.


The Chronotypes

Check out the chronotypes below and let us know in the comment section which one sounds like you!

Wolves

Alright, night owls, this is your group. Just like these nocturnal creatures, you are most alert at night. Wolves tend to stay up later and struggle with waking up early.

Only about 15% of the population falls into this group. Wolves are more productive in the later afternoon and evening.

Sleep experts recommend that wolves set their alarm for 7 a.m. (snooze for 30 minutes) and go to sleep by midnight.

Lions

Lions are the new early birds. Like these wild cats, you are most alert in the morning. You have no trouble waking up and getting to work. But, lions tend to feel the afternoon slump. And by the evening, they feel drained.

About 15% of the population identifies as a lion. Sleep experts recommend that lions wake up around 5:30 a.m. and go to sleep by 10:30 p.m.

Bears

No, you don’t need to hibernate. But, like these diurnal (awake during the day, asleep at night) creatures, you follow the solar cycle. Bears generally feel awake during the day and need 8-hours of solid sleep at night.

About 50% of the population falls into this category. This group is productive in the morning and struggles with the mid-afternoon slump. Sleep experts recommend that bears wake up around 7 a.m. and go to sleep by 11 p.m.

Dolphins

Dolphins “only sleep with half of their brain at a time?” Sound familiar? Well, this is the insomniac (often self-diagnosed) group. You might be anxious and have trouble turning your brain off at night. Dolphins usually don’t get a complete night’s sleep.

About 10% of the population falls in this category. And even though they wake-up tired, dolphins are most productive by mid-morning.

Sleep experts recommend that dolphins get up around 6 a.m. and try to sleep around midnight.

Sleep Like an Animal

Who doesn’t want a better night’s sleep and a more productive day? Start scheduling your days based on your chronotypes! Once you know more about your chronotype, you can form sleep patterns that work with (not against!) your body’s natural rhythms.

So what are you waiting for? Here in Kaiyan, we are embracing our inner animals and start following our optimal sleep schedule.

Red Light Therapy and Sun Damage

When summer rolls around, we all head outside, absorbing as many rays as we can. And the proof is in the numbers, with the top five summertime activities being barbeques, going to the beach, attending festivals, going for a hike, and exploring nature. When the sun comes out, people flock to the outdoors with good reason. We need the sun’s rays to survive.

However, many of us go a little overboard. Some lather on tanning oil or skip sunscreen to make sure we receive as much pigmentation as possible. And yes, we need vitamin D, but overexposure leads to sun damage, including sunspots and wrinkles.

However, it doesn’t end there. Neglectful sun exposure can also lead to skin cancer. While the damage has already been done from years of sunbathing and tanning oils, there are ways we can repair sun-damaged skin, reduce wrinkles and sunspots.

It can help repair the sun damage done to our skin and turn back the clock with red light therapy.

What is Sun Damage?

In the end, skin damage comes from overexposure to ultraviolet (UV) light. When we sunbathe, our skin naturally responds to the sun by protecting itself from UV light. What does our body do? Well, it produces melanin, which darkens the skin to reflect the UV light. So your summer tan is actually a defense mechanism. There are a few different types of sun damage to be aware of:

Melasma: It’s an overproduction of melanin that causes brown or gray patches to form on the skin.

Wrinkles: UV light breaks down the collagen and elastin in the skin, losing its firmness and causing wrinkles.

Sunburn: Sunburns are an inflammatory reaction to UV radiation damage to the skin. The body responds by repairing or removing the damaged cells, which results in redness and peeling.

Sun Spots: Overexposure to UV rays causes an increase of melanin production that builds up in clusters, producing dark spots on the skin.

Actinic Keratosis (AK): Causes a scaly patch of skin on the body from overexposure to UV light. This is particularly dangerous as around 10% of actinic keratosis becomes cancerous.

How Red Light Therapy Reverses Sun Damage

If you’re wondering whether sun damage is reversible or not, the answer is yes. Red light therapy uses infrared and red light to enhance the body’s healing process. Red light therapy increases the body’s collagen, elastin, and immune response; it can remove and repair dead or damaged skin cells.

By increasing collagen production, it’ll help smooth and firm the skin, reducing the appearance of fine lines and wrinkles. Besides, red light therapy also protects existing collagen, which helps keep the skin’s elasticity.

However, red light therapy doesn’t only reduce fine lines and wrinkles. It can also help with more serious skin conditions such as actinic keratosis. It can aid in removing actinic keratosis spots from the skin with photosensitizing medication and red light therapy.

Sun damage is the main cause of aging skin and can lead to serious health issues. Naturally, some sun damage forms cannot be treated, especially for those who work consistently outdoors. However, tackling sunspots, wrinkles, sunburns, and actinic keratosis is achievable through red light therapy treatment.

It’s important to point out that while red light therapy does reverse sun damage, it can prevent future damage — but you should always wear a broad-spectrum sunscreen when outdoors and reapply after swimming or sweating.

Reversing past mistakes are possible with light therapy, but we also want to look at the future. Luna’s red light therapy will tackle previous sun damage and rejuvenate the skin, while sunscreen will prevent future damage.

We hope you continue to enjoy the sun’s incredible rays safely while enjoying the incredible skincare results of Lunas light panels.

Stretch Marks & Light Therapy

Why Do We Get Stretch Marks?

A stretch mark is a type of scar called striae, meaning “thin, narrow scar”. In people who develop stretch marks, the skin has stretched faster than it can grow, such as during pregnancy, growth spurts, or rapid fat or muscle gain. The abrupt stretching causes the collagen and elastin proteins responsible for the skin’s structure and elasticity to rupture. This, in turn, causes the dermis to tear.

As the dermis tears, the body’s healing mechanisms spring into action to close the wound as quickly as possible to prevent infection and further damage.

Normally, as the skin regenerates and grows, it’s an elegantly organized latticework of collagen and elastin proteins. But when the skin tears, the body doesn’t have time to build an elegant structure to fill in the gap. Time is of the essence in any wound repair, including torn skin.

The collagen clumps together hurriedly, aiming for efficient closure of the wound before infection can set in. “Scarring is the result of a system that has learned to respond extremely quickly to a wound,” says Dr. John Newman, a cosmetic surgeon and researcher at the Laser Center of Virginia in Virginia Beach.

This haphazard process results in tough and functional but unattractive tissue — what we know as a scar. “It is kind of like nailing down a crisscross of two-by-fours over a hole in a deck,” says Newman. “It seals the hole, but it doesn’t look very nice.”

Newly formed stretch marks are darker than the surrounding skin and can be slightly raised, itchy, or painful. If they’re left untreated, they become permanent scars. Their color will lighten, and their appearance will fade below the top layer of the surrounding skin.

The bigger mystery is why stretch marks don’t disappear over time as the skin regenerates. The key lies in the information that emerging cells receive from adult cells in the area. Skin cells, whether they’re normal cells or scar cells, regenerate about once every 30 days. Growth of new skin cells begins at the bottom-most layer of the scar, and older (dying) cells are pushed to the surface where they naturally slough off.

However, Neuman explains that that that that emerging cells “learn” from their immediate neighbors and predecessors and develop the same characteristics as ir replacement their replacement cells. As a result, any emerging cell in contact with scar cells will become new scar tissue rather than normal skin tissue.

Red Light Therapy For Stretch Marks

If you have tried to get rid of stretch marks, perhaps you’ve used specialized creams that contain retinoids. These work to some extent, but only if you catch your stretch marks early and treat them while they’re still forming. Retinoids work by stimulating collagen production. However, they can irritate sensitive individuals, and doctors often recommend that pregnant women avoid anything containing retinoids.

Another common treatment, known as microdermabrasion, essentially involves “sandblasting” the skin with tiny crystals. This sloughs off dead skin

cells and stimulates the production of collagen. Microdermabrasion is a fairly harsh treatment that can lead to irritation and damage, especially to sensitive skin.

The most extreme treatment for stretch marks is plastic surgery, such as a mini tummy tuck. This may be effective, but there are risks associated with any invasive procedure and the high cost.

Is there a better option for restoring the appearance of the skin? The answer is yes, absolutely. Also known as photobiomodulation and low-level light therapy (LLLT), red light therapy improves skin appearance, reduces signs of aging, treats chronic skin conditions, reduces scarring, and promotes skin wound healing.

When red light therapy is used, visible red light and invisible near-infrared (NIR) light are applied to the skin with LED bulbs' devices. Wavelengths of light are measured in nanometers (nm), with red light ranging from 630nm to 660nm and NIR light ranging from 810nm to 850nm. Human cells respond favorably to these wavelengths, similar to how natural sunlight affects plant cells by stimulating more energy and optimization of cell function.

When the red light is shone on bare skin, it soaks into the mitochondria, colloquially referred to as the powerhouses of cells' energy factories. The mitochondria are, in turn, stimulated to produce more adenosine triphosphate (ATP), which is the primary cellular fuel. This energizes cells to perform their normal functions, from fighting off pathogens to performing repair and regeneration.

Improved Blood Flow

Proper healing relies on good circulation to the skin. Red light promotes the proliferation of endothelial cells, which make up the inner layer of capillaries (the tiny blood vessels that deliver oxygen and nutrients throughout the body). This was the focus of a 2017 study by a team of researchers from Austria, who found that red light consistently increased migration and proliferation of endothelial cells.

Without proper blood circulation, there would be no healing since endothelial cells also deliver white blood cells to the sites they need. In skin wound healing, white blood cells are necessary to protect the vulnerable area from infection while the wound closes up.

Reduced Inflammation

Acute inflammation results in the redness that’s noticeable in fresh stretch marks. This is a normal and necessary part of the tissue regeneration scar's process. Acute inflammation, which is a function of the immune system, actually sets the stage for normal tissue repair and regeneration. Inflammation is quickly followed by the production of new skin structures — which, as previously described, are hastily assembled to ensure that the torn skin doesn’t become infected.

But sometimes, the inflammatory process continues after the wound has healed, leading to chronic inflammation. It can lead to a variety of widespread problems throughout the body, including disease. “Some inflammation is good,” says Dr. Robert H. Shmerling, an associate professor of medicine at Harvard Medical School. “Too much is often bad. The goal is to recognize when inflammation is simply doing its job, and when it can potentially cause problems.”

Hundreds of studies have shown how red light therapy can significantly reduce inflammation. Many of these were conducted by Dr. Michael A. Hamblin, an associate professor of dermatology at Harvard Medical School and a noted expert on red light therapy. In the final report of a 2017 study, Hamblin refers to red light therapy’s “pronounced anti-inflammatory effects.”

Mobilize Stem Cells

During the skin-rebuilding phase, stem cells, which are unspecialized “master” cells, mobilize to the site and develop into most any type of specialized cells that are needed by the body. Ideally, they develop into normal skin cells, rather than scar tissue, to replenish damaged or destroyed cells due to skin tearing.

Red light has been shown to activate stem cells. As Barbara Gefvert, editor-in-chief of BioOptics World, explains: “Recent research shows … that noninvasive application of light can boost the natural growth of an individual’s own stem cells to enable exciting new treatments.” Stem cells can assist with the tissue regeneration process and stimulate normal and healthy behavior in existing cells. This can prevent the formation of new stretch marks and gradually reduce the appearance of existing stretch marks.



Lighting the Way Back for Astronauts - Light Therapy & NASA

In 1993, Quantum Devices, Inc. (QDI), of Barneveld, Wisconsin, began developing the HEALS (High Emissivity Aluminiferous Light-emitting Substrate) technology high-intensity, solid-state LED lighting systems for NASA Space Shuttle plant growth experiments. The company evolved out of cooperative efforts with the Wisconsin Center for Space Automation and Robotics (WCSAR) at the University of Wisconsin-Madison — a NASA center for the Commercial Development of Space. Ronald W. Ignatius, QDI’s president, and chairman represented one of WCSAR’s industrial partners at the time. WCSAR was conducting research on light sources for promoting food growth within closed environments where humans would be present for a long duration, such as the Space Shuttle and the International Space Station.

With the support of WCSAR, Ignatius experimented with LEDs, which provide high-energy efficiency and virtually no heat, despite releasing waves of light 10 times brighter than the Sun. Ignatius admits that some scientists involved in the project were skeptical at first, thinking that the idea of using LEDs to promote plant growth was far-fetched. However, the experiments demonstrated that red LED wavelengths could boost the energy metabolism of cells to advance plant growth and photosynthesis. This finding prompted Ignatius to develop a line of LED products that emit the exact wavelength of light that plants use in photosynthesis.

“Our company gives credit to Dr. Ray Bula, the director of WCSAR, for having the foresight to go against the prevailing dogma of the time and design the first plant experiment using monochromatic light to grow lettuce plants,” Ignatius proclaims.

In 1989, Ignatius formed QDI to bring the salt grain-sized LEDs to market. In October 1995, the light sources made their Space Shuttle flight debut on the second U.S. Microgravity Laboratory Spacelab mission (STS-73, Columbia).

Growing

When NASA determined that red LEDs could grow plants in space, Marshall Space Flight Center awarded QDI several Small Business Innovation Research (SBIR) contracts to investigate the broad-spectrum diodes' effectiveness in medical applications. The contracts, issued from 1995 to 1998, focused on increasing energy inside human cells. NASA hoped that the LEDs would yield medical benefits on Earth and stem bone and muscle mass loss in astronauts, which occurs during long periods of weightlessness. (In space, the lack of gravity keeps human cells from growing naturally.) Furthermore, since wounds are slow to heal in a microgravity environment, LED therapy could accelerate healing and keep what would be termed as minor wounds on Earth from becoming mission-catastrophic in space.

In addition to promoting cell growth, the red LEDs are capable of activating light-sensitive, tumor-treating drugs that, when injected intravenously, could destroy cancer cells while leaving surrounding tissue virtually untouched. The technique, approved by the U.S. Food and Drug Administration (FDA) for use in laboratory and human trials, is known as Photodynamic Therapy.

With the SBIR assistance from NASA, QDI set out to alter a surgical probe that could emit long waves of red light to stimulate a Benzoporphyrin-derivative drug called Photofrin, which delivers fewer post-operative side effects than comparable drugs. Ignatius also developed a friendly and successful working relationship with Dr. Harry Whelan, pediatric neurology and director of hyperbaric medicine at the Medical College of Wisconsin in Milwaukee. The two had met after Ignatius came across a newspaper article highlighting Whelan’s ground-breaking brain cancer surgery technique, which uses drugs stimulated by laser lights to accelerate healing. Accordingly, QDI provided more than $1.25 million from its SBIR contracts to support Whelan’s pioneering photobiomodulation research and bring him on board to help improve the surgical probe.

Collectively, Ignatius, Whelan, and researchers from NASA successfully altered the probe for pediatric brain tumors and the prevention of oral mucositis (a common side effect of chemotherapy and radiation treatments) in pediatric bone marrow transplant patients at the Medical College of Wisconsin. In May 1998, a 20-year-old female became the first patient to undergo surgery with the modified probe. The young woman had endured six brain surgeries and chemotherapy and radiation treatments over a span of 10 years, but her aggressive cancer kept coming back. Having exhausted all of her conventional treatment options, she turned to the NASA-sponsored Photodynamic Therapy technology.

During the procedure, surgeons excised as much of the recurring brain tumor as they could then injected the light-activated Photofrin into her bloodstream and inserted the LED probe into the remaining tumor tissue. The probe, which casts long wavelengths that generate less heat and penetrate deeper into tissue than the shorter wavelengths of traditional medical lasers, proved to be both safe and effective, as the tumor never returned, and the patient recovered with no complications. A second operation that took place 3 months later on a male patient was also deemed successful by Whelan and his Medical College of Wisconsin surgeons' team.

FDA-approved clinical trials continued at several other facilities over the next 3 years, including the Roswell Park Cancer Institute in Buffalo, New York; Rush-Presbyterian-St. Luke’s Medical Center in Chicago; and the Instituto de Oncologia Pediatrica in Sao Paulo, Brazil. QDI became recognized as a U.S. Space Foundation “Space Technology Hall of Fame” award recipient in 2000 and a Marshall Space Flight Center “Hallmark of Success” in 2004.

Product Outcome

The positive clinical trial results and continued support from NASA and follow-on research grants from the Defense Advanced Research Projects Agency helped QDI and the Medical College of Wisconsin fully transition space technology into a new, non-invasive medical device. The WARP 10 (Warfighter Accelerated Recovery by Photobiomodulation) is a high-intensity, hand-held, portable LED unit intended for the temporary relief of minor muscle and joint pain, arthritis, stiffness, and muscle spasms. It also promotes the relaxation of muscle tissue and increases local blood circulation. Unlike the surgical probe, the WARP 10 does not require intravenous medicine; instead, the unit can be placed directly on the skin where treatment is to occur.

The WARP 10 was designed to aid armed forces personnel on the front lines with immediate first aid care for minor injuries and pain, thereby improving combat endurance. The “soldier self-care” device produces 80 times more photon energy than a 250-Watt heat lamp, yet it remains cool to the touch. The power advantage reduces the time required for each therapeutic dose and provides for faster multi-dose exposures when needed, without the harmful effects of ultraviolet solar radiation. The U.S. Department of Defense and the U.S. Navy are currently issuing WARP 10 to crews on submarines and Special Forces operations.

QDI has introduced an FDA-approved consumer version sharing the same power and properties of the military model as an alternative to the cost and complications associated with the overuse of non-steroidal anti-inflammatory drugs (NSAIDs) for persistent pain relief. According to a Mayo Clinic study, adverse events associated with the use of NSAIDs are reported more frequently to the FDA than such events associated with any other group of drugs. Furthermore, conservative calculations for the United States estimate that approximately 107,000 patients are hospitalized each year for NSAID-related gastrointestinal complications. At least 16,500 NSAID-related deaths occur annually among arthritis patients alone, according to compiled research.

Light and the Moon

The moon shines because its surface reflects light from the sun. And even though it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it.

The moon’s perceived brightness from Earth depends on where the moon is in its orbit around the planet. The moon travels once around Earth every 29.5 days, and during its journey, it’s lit from varying angles by the sun.

This moon’s movement around the Earth — and the simultaneous orbiting of Earth around the sun — account for the moon’s different phases (full moon, quarter moon, etc.). At any given point in the moon’s trajectory around the Earth, only half of its surface is facing the sun, and therefore, only half of the moon is lit up. The other half of the surface faces away from the sun and is in shadow.

Now, I took my first moonlight photograph in 1998, using my father’s old Kodak camera. The results were almost invisible, of course. It was pretty clear that I had no idea what I was doing. But I did know that the feeling of being out under the stars was one that I needed to capture somehow, and I had to find a way to go about doing it.

I left the moonlight photography for a while. Some years later, I read that the brightness of moonlight is extremely variable over a range of many stops and that it was nearly impossible to figure out the brightness of a given scene was going to be ahead of time. The brightness of moonlight under clear skies is as easily predictable as is the brightness of sunlight under similar conditions.

Several things cause moonlight brightness to vary. The most obvious is the moon’s phase. The brightness of moonlight varies by approximately a factor of 10 between the quarter phase and full moon, based on a diffuse reflection and the geometry of the positions of the earth, sun, and moon alone. This is about three and a half stops of light, which is substantial. Another factor is the distance between the earth, moon, and sun, which changes due to the earth and lunar orbits not being perfect circles. The distance from the earth to the sun varies from 0.9833 Astronomical Units at perihelion to 1.0167 Astronomical Units at aphelion. The earth’s distance to the moon varies from 356,400 kilometers at extreme perigee to 407000 kilometers at extreme apogee. The amount of light that falls on a body varies with the inverse square of the distance from the light source, so the combined effect of these distance variations can be quite pronounced. The range of lunar illumination variation is 6.9% for variation in sun distance and 30% for moon distance variation. This amounts to about one-third stop of brightness, which enough to change the mood of a photo when slide films are used.

The third factor in moonlight brightness is the so-called opposition effect. The surface of the moon is covered with small glassy particles that can serve as wonderful retro-reflectors. If you are within a small angle to the line between the sun and moon, the amount of light coming from the moon increases dramatically relative to what you would expect from a diffuse reflection alone. There is quite a range in the magnitude of this effect presented in scientific literature, ranging from a factor of 1.35 to 20! Whatever value you choose to use, the effect is at least one-third stop of light, making it significant to use slide film.

The final parameter that introduces variation into moonlight brightness is atmospheric attenuation, or atmospheric extinction, to use astronomer’s jargon. This accounts for the amount of light absorbed or scattered when light from the moon passes through the earth’s atmosphere. There are two factors involved: the amount of reduction per a given amount of air transited by the light (the “extinction coefficient”) and the amount of air in the light path (“air mass”). Three principal phenomena contribute to the extinction coefficient: molecular absorption, molecular (Rayleigh) scattering, and aerosols’ scattering (particles larger than molecules). See my web page on atmospheric attenuation for more on these individual factors. Overall, an extinction coefficient value is small for dry, clear air but can be huge for moist, dusty air. And the amount of air the light passes through can vary from one “air mass” with the moon directly above you to forty “air masses” when the moon is on the horizon.

So how bright can moonlight be? The brightest moonlight occurs with the moon at perigee and the earth at perihelion, right at the full moon phase. You can never have the moon at its theoretically fullest phase, right opposite the earth from the sun, because whenever the moon goes there, it enters the earth’s shadow, and we get a lunar eclipse! But assuming the eclipse didn’t happen, we could assume the following: a phase angle of zero, apparent air with an “extinction coefficient” of 0.11 magnitudes per air mass, the moon on the zenith so that the moonlight passes through a single “air mass,” the brightness would be 0.0462-foot-candles (LV -2.0), neglecting “the opposition effect.” If we include “the opposition effect,” the brightness could be anywhere from 35% to 20 times brighter (note that 35% is the more accepted value in the scientific literature, which would give an LV of -1.7). I once measured moonlight brightness with a Gossen Luna-Pro incident light meter in mid-winter on the Kelso Dunes at LV=-2.2, so this is a believable result.

There is a rule of thumb, sometimes called the Looney 11 Rule, which says we should treat the moon as being 250,000 times dimmer than the sun. This would have us use a shutter speed 18 stops slower than the 1/(film speed) value that is used in the “Sunny 16 Rule”, which works out to about 44 minutes at f/16 under moonlight conditions with the film having an ISO speed rating of 100 (uncorrected for reciprocity failure!). This is close enough to be useful under full moonlight conditions given an average earth-moon and earth-sun distance, with the moon high in the sky and clear air. Actually, since the sun has an astronomical visual magnitude of -26.74 and the full moon an astronomical visual magnitude of -12.73, the sun is more like 402,000 times brighter than the moon 18.6 stops. Thus using this rule pretty much ensures a minimum of 2/3 stop underexposure — which may actually be fine, since most of the time you want an underexposure to give the impression of the night in the image.

Surprisingly, the moonlight is actually a slightly warmer color than sunlight, as the moon reflectance is higher for longer wavelengths. Yet, on clear nights, with the full moon high in the sky (as little atmospheric influence as possible), the landscape around us appears blueish because of the Purkinje effect: at low illumination levels, our red color sensitivity decreases (as our vision system gradually switches from daylight (cones) to night time vision (using rod cells)).

That’s why the sunlight looks “warm” (more yellow), and the moonlight looks “cold” (bluer — because the insufficient light level changes our color perception), even though the real colors are pretty much the same.

In fact, this is can even become a real problem when taking very long exposure photos at night! They look almost like daylight photos, destroying the intended atmosphere of mystery. Objectively, the photograph is correct, but it is not what we see with our own eyes. Add some blue tint and the night feeling is back.

The Sun and Us

Nothing is more important to us on Earth than the Sun. Without the Sun’s heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.

We know the Sun through its heat and light, but other, less obvious aspects of the Sun affect Earth and society. Energetic atomic particles and X-rays from solar flares and other disturbances on the Sun often affect radio waves traveling the Earth’s ionosphere, causing interference and even blackouts of long-distance radio communications. Disturbances of the Earth’s magnetic field by solar phenomena sometimes induce huge voltage fluctuations in power lines, threatening to blackout cities. Even such seemingly unrelated activities as the flight of homing pigeons, transatlantic cable traffic, and the control of oil flow in the Alaska pipeline apparently are interfered with by magnetic disturbances caused by events on the Sun. Thus, understanding these changes — and the solar events that cause them — is important for scientific, social, and economic reasons.

We have long recognized the importance of the Sun and watched it closely. Primitive people worshiped the Sun and were afraid when it would disappear during an eclipse. Since the early seventeenth century, scientists have studied it with telescopes, analyzing the light and heat that manage to penetrate our absorbing, turbulent atmosphere. Finally, we have launched solar instruments and ourselves-into space to view the Sun and its awesome eruptions in every aspect.

Once we looked at the Sun by the visible light that reached the ground, it seemed an average, rather stable star. It was not exactly constant, but it seemed to vary in a fairly regular fashion, with a cycle of sunspots that comes and goes in about eleven years. Now the Space Age has given us an entirely different picture of the Sun. We have seen the Sun in other forms of light-ultra violet, X-rays, and gamma rays that never reach the ground from space. This radiation turns out to be far more responsive to flare eruptions and other so-called solar activity.

We now see the Sun as a place of violent disturbances, with wild and sudden movements above and below its visible surface. Besides, solar activity's influence seems to extend to much greater distances than we had believed possible. New studies of long series of historical records reveal that the Sun has varied in the past in strange and unexplained ways. Scientists wonder how such variations might affect the future climate on Earth.

We have obtained a clearer picture of the scope of the Sun’s effects. Its magnetic field stretches through interplanetary space to the outer limits of the solar system. Steady streams and intense storms of atomic particles blow outward from the Sun, often encountering our Earth's atmospheres and the other planets. The spectacular photos of the Earth from space show only part of the picture. Instruments carried on satellites reveal a wide variety of invisible phenomena — lines of magnetic force, atomic particles, electric currents, and a huge geocorona of hydrogen atoms — surrounding the Earth. Each is as complex and changing as the visible face of the globe. The Earth’s magnetic field extends tens of thousands of miles into space, and many different streams of electrons and protons circulate within it. Huge electric currents flow around the Earth, affecting their high-altitude surroundings as well as our environment at ground level.

Space observations have greatly expanded our ability to look at the Sun, interplanetary space, and the Earth's immediate surroundings. We can now “see” many phenomena that are completely undetectable from the Earth’s surface, and we now have a much better, more complete, and more coherent picture of how events in one part of our solar system relate to activity in another.

The Sun as a Star

We sometimes forget that there is one star that is easily visible in the day time: our Sun. The Sun is the only star close enough to be studied in detail, but we are confident that all the processes in the Sun must also occur in billions of distant stars throughout the universe. To understand the nature and behavior of other stars, we must first understand our own. At the same time, observations of other kinds of stars help put the Sun in perspective.

The Sun is a relatively typical star among the approximately 100 billion stars in our Milky Way galaxy. The masses of most other stars that we see range from approximately one-tenth of the mass of the Sun to about 30 solar masses. The surface temperatures of most stars range from about 2000° C to 40,000° C. Although the Sun is somewhat on the cool side at about 6000° C, hot stars are rare, and most normal stars are cooler than the Sun. Compared to some of the explosive stars — novae, and supernovae — which sometimes appear in the sky, the Sun is stable and ordinary.

This long-term stability of our Sun probably was crucial for the development of life on Earth. Biologists believe that a relatively stable average temperature had to prevail on Earth during the past 3 billion years for life to evolve to its present state. The relative stability of the Sun is also important to astronomers trying to understand the basic nature of it and other stars. Violent activity in the Sun could mask the more subtle and long-enduring processes, which are the basic energy transport mechanisms of our star. Fortunately, they are not hidden, and we have been able to map the trend in solar properties with height above the visible surface.

Above the minimum temperature region in the photosphere, we have measured how the gas gets hotter as it thins out with height. The chromosphere and corona, each hotter than the layer below, are warmed by the transfer of energy from below through processes that are still not well understood.

Until space observations became possible, we knew nothing about coronae in any other stars and had only marginal information about stellar chromospheres' properties. Now, space observations have shown us that a large fraction of the stars in the sky have chromospheres and coronae.

On several dozen stars, we have even detected activity that may be connected with sunspot (or “starspot”) cycles like those of our own Sun. X-ray telescopes carried on satellites have recorded flares in other stars that are far more powerful than the already impressive flares of the Sun. By observing the strength and frequency of these events on stars with masses, ages, and rotation rates which differ from those of the Sun, we search for answers to such basic questions as: “How does the sunspot cycle period depend on the star’s rotation rate?” or “What is the relation between the temperature of a star’s corona and the strength of its magnetic field?” By deciphering the general pattern of stellar properties, we can better understand what makes things happen on the Sun.

The Sun presents us with a bewildering variety of surface features, atmospheric structures, and active phenomena. Sunspots come and go. The entire Sun shakes and oscillates in several different ways at the same time. Great eruptions called prominences hang high above the Sun’s surface for weeks, suspended by magnetic force, and sometimes shoot abruptly into space from the corona. The explosions called solar flares emit vast amounts of radiation and atomic particles in short periods of time, often with little or no warning.

Space observations have discovered many new aspects of solar events hidden from ground-based observatories—the Sunshine's hottest spots primarily in ultraviolet and X-rays, rather than in visible light. Thus, only from space can we map high-temperature solar flares' true structure and determine their physical conditions. Space observatories have shown us the higher, hotter layers of the Sun’s atmosphere that normally are invisible from the ground. Instruments on satellites revealed that in flares and other violent disturbances, the Sun acts like an atomic accelerator, driving electrons and protons to velocities approaching the speed of light. At such high speeds, the particles emit the high-energy X-rays and gamma rays measured by our satellites. Sometimes they even induce nuclear reactions on the surface of the Sun.

Two aspects of our improved knowledge of the Sun deserve special attention. One is the role of magnetic fields in determining virtually all aspects of the Sun’s upper atmosphere's structure and behavior. The other is discovering the solar wind, a stream of atomic particles that constantly evaporate from the Sun’s atmosphere and are accelerated to speeds of hundreds of kilometers per second, escaping into space in all directions.

The Earth-Sun Battle

For any solar particle to reach the Earth, it must first pass through the Earth’s magnetic field. Before the solar wind was discovered, the Earth’s field was thought to be symmetrical, resembling a huge bar magnet, fading off indefinitely into space. However, we now know that the solar wind shapes the Earth’s magnetic field's outer regions and is sharply bounded. Outside the boundary, space is dominated by the solar wind and the interplanetary magnetic field. Inside the boundary is the region or magnetosphere dominated by the Earth’s magnetic field. The measurements from many space missions have been combined to reveal that the solar wind blows out the Earth’s magnetosphere into a teardrop shape. The head of the drop extends only about 10 Earth radii, or about 65,000 kilometers (40,000 miles) “upwind” toward the Sun. The tail of the drop stretches away in the direction opposite the Sun, actually reaching beyond the Moon’s orbit. This long magnetotail extends more than 600,000 kilometers (370,000 miles) from the Earth.

At the boundary of the magnetosphere, there is a constant struggle between the Earth's magnetic field and the forces of the Sun. Buffeted by fluctuations in the solar wind velocity and density, the magnetosphere’s size and shape are continuously changing. When the solar wind strikes the magnetosphere, shock waveforms are analogous to the sonic boom preceding a supersonic airplane. Inside the boundary with the solar wind, the magnetosphere remains an active region. It contains two belts of very energetic charged atomic particles trapped in the Earth’s magnetic field hundreds of miles above the atmosphere. These belts were discovered by Professor James Van Allen of the University of Iowa and his colleagues in 1958, using simple radiation detectors carried by Explorer 1, the first U.S. satellite.

The Northern and Southern Lights: Gifts from the Sun

The structure of the Earth’s magnetosphere also controls aurorae's behavior, seen in our night skies. Pre-Space Age textbooks stated that aurorae are produced by photons emitted from the Sun and reach the Earth’s upper atmosphere through gaps in the Earth’s magnetic field at the north and south magnetic poles. According to the theory, these protons strike oxygen atoms in the atmosphere, and the collisions cause the glow, which we call the Northern Lights.

This view has changed in the Space Age. The data collected by many spacecraft showed that the situation is more complicated. Particles from both the solar wind and from the Earth’s atmosphere apparently are stored in the magnetotail. From there, they periodically are violently ejected into the northern and southern polar regions of the atmosphere along the Earth’s magnetic field. They are accelerated to high speeds by a process not yet fully explained. The magnetotail is, in effect, a reservoir of particles that is periodically refilled. When the Sun is active during maximum sunspot years, this process is especially intense and frequent, and the aurorae are brighter and move closer to the equator.

Light Therapy — Wound Healing in Horses

LED light therapy is really a way to help the body heal itself. In Kaiyan, we have used specific wavelengths of light absorbed by a photo acceptor, cytochrome c oxidase, within the cell's mitochondria. The energy (photons) from the lights increases the energy within the cell, which speeds up the healing process. The lights must be specific wavelengths and must be delivered at a specific dosage. We use two wavelengths in our light therapy pads, a visible red and a near-infrared wavelength. Using both red and near-infrared lights is beneficial because different depths of tissue absorb the wavelengths. The combination of the two work in concert to provide benefits for soft tissue injuries, inflammation, ligament soreness, tendon problems, sore backs, splints, strains, stifle issues, sprains, swelling, shoulder pain, hip pain, sore backs, sore necks, salivary gland problems, wounds, cuts, scrapes, arthritis pain and for trigger points and acupuncture points. Visible red light (660nm) is absorbed by skin layers very efficiently and best for uses such as stimulating trigger and acupuncture points and treating wounds and infections. Near-infrared light (850nm) penetrates to a deeper level has been used to treat concerns of tendons, ligaments, bones, joints, and muscle.

When nursing skin wounds of horses, such as lacerations or deep abrasions, owners often seek ways to maximize healing and minimize scarring, particularly when high-motion areas are involved.

“In horses, dermal injuries can be slow to heal, cause excessive scarring, and prolong a horse’s layup. In some cases, especially wounds of the limbs, proud flesh may develop in response to exuberant healing efforts,”

Said Catherine Whitehouse, M.S., an advisor for Kentucky Equine Research.

Medical-grade honey, fly larvae, and other strategies have been tested to speed wound healing. Most recently, Swedish researchers explored the use of irradiation with light-emitting diodes (LEDs), called photobiomodulation, in jump-starting wound repair. The LED used in the study features a pulsating visible red light and near-infrared (NIR) light.

“Some research shows that LEDs stimulate wound healing and decrease swelling and inflammation. With this in mind, veterinarians were hopeful that low-level light treatment could expedite wound repair in horses,” Whitehouse explained.

In this study, researchers created two circular skin wounds on the necks of eight healthy horses. One wound was treated with a combination of red light and NIR light for 4 minutes and 40 seconds on specific treatment days during the 25-day study period. The other wound on each horse remained untreated. The researchers photographed and assessed the wounds for the degree of swelling using ultrasound.

Area and degree of swelling did not differ between treated and untreated wounds, prompting researchers to conclude that red light and NIR light had no clinically relevant positive effect on horses' wound healing.

A veterinarian should examine all significant wounds. Extensive wounds with significant blood loss or tissue damage should be considered medical emergencies.

Keep Your Skin Healthy with Red Light Therapy

Skincare doesn’t just affect the way you look. It also plays a huge role in your overall health — from body temperature to hormone regulation to your immune system. If you’re into skincare as much as we are, one of the many ways that can help you keep your skin healthy is red light therapy. In this article, we’ll take a deep dive into why you should take care of your skin, and we’ll also discuss how red light therapy devices can help you achieve your skin goals.

Are you ready? Let’s go straight into it.

Why Do You Need to Take Care of Your Skin?

As the largest organ in our body, your skin is your body’s first defense line to bacteria, germs, viruses, etc. It’s a vital part of the immune system and some processes in your body, such as temperature control, blood circulation, and hormone production.

Main Functions of the Skin

Let’s take a look at the skin's main functions to help you understand how essential it is for you to take care of this vital organ.

1. Defense and Immunity

The skin is an active immune organ, and it serves as our physical barrier from the dangers of the environment. It helps protect our bodies from diseases, germs, viruses, dirt, UV radiation, and potential thermal and physical injuries. It also helps detect and fight off infection, toxins, allergens, hazardous substances, and carcinogens.

2. Temperature Regulation

Aside from protecting us from extreme cold or heat, the skin also helps prevent moisture loss, keeping us from being dehydrated.

3. Sense of touch

The skin has a somatosensory system that is composed of touch receptors and nerve endings. This system is responsible for the sensations we feel, including pain, pressure, vibrations, smoothness, roughness, heat, cold, tickle, itch, and more.

4. Storage and Production of Vitamin D

Your body also uses your skin's deeper layers to store metabolic products, fat, and water. The skin is also responsible for producing vitamin D, supplied in the body when the skin gets enough sunlight exposure.

5. Beauty

Need we say more? Your skin plays a huge part in your appearance. Of course, when your skin is healthy, you also look glowing, radiant, and definitely more attractive.

Red Light Therapy and Keeping Your Skin Healthy

Before we proceed with the “how,” let’s first define what red light therapy is. Red light therapy is a non-invasive treatment option for different kinds of medical conditions. It is also used for health improvement and various aesthetic procedures.

Decades ago, red light therapy machines were only available in clinics, high-end salons, and spas. Nowadays, red light therapy devices can be bought and used by anyone. In fact, you can do red light therapy at the comfort of your home and incorporate it into your skincare routine.

How Does Red Light Therapy Work?

Red light therapy works by delivering wavelengths of red and near-infrared (NIR) light to our cells and skin. Besides helping enhance cellular function, red light therapy also helps stimulate the mitochondria and produce ATP (adenosine triphosphate) energy. This treatment option usually takes only about 10 minutes per session.

How Does Red Light Therapy Help Keep Your Skin Healthy?

Our skin relies on millions of cells to be able to perform its functions. When our cells experience homeostasis or a state of balance, our skin and body perform (and look) better. And as mentioned above, red and NIR light enhances cellular function while also preventing inflammation and oxidative stress. Red light therapy helps make your skin look and feel softer, smoother, and healthier.

Besides, red light therapy also helps damaged tissues heal and regenerate faster. It also has anti-inflammatory benefits, potentially increasing blood flow to damaged and inflamed tissues and reducing oxidative stress.

Final Thoughts

Skincare is self-care, as keeping your skin healthy also produces multiple benefits to your health. Thankfully, aside from proper hygiene, regular exercise, a balanced diet, and an established skincare routine, red light therapy can also improve your overall skin health.

The Light for your Wounds

I remember how I used to come home with a bruise or cut every day after playing basketball in my childhood. Cuts and bruises were a part of the game, but my mother never took them lightly.

They may not seem like a tiny problem, but sometimes even a small wound can affect critical ways. It can lead to an infection as the cut exposes your body to external bacteria. This is why it important not to neglect the wounds.

What Happens When we Get a Cut?

Do you know what exactly happens when we get a cut?

In a small cut, the skin gets punctured, and the regular blood vessels get damaged. The effect is on the dermis layer. Whereas in the case of a deep cut, the impact is majorly on the tissues and the blood vessels break down completely results bleeding.

How our Body Reacts to Wounds?

When you get a cut, the body gets help from cells like neutrophils and immune cells. The section starts clotting the blood and reduces the blood flow. Antibodies, proteins clean up the site and eat the dead skin cells and other wastes.

Once the cut is free from germs, the skin growth gets started, and your body starts to rebuild the lost tissues and fix the broken blood vessels with the new ones. This repair work is done by cells called fibroblasts. In the last stage of wound healing, a lot of remodeling done to make the vessels and tissue functional again.

The Light on the Wounds

No wonder science and technology have covered a long way to make human life easier. Now wounds can be treated with light therapy.

Yes, light therapy!!

That sounds out of the ordinary. But light therapy can heal your wounds by 200%!!

Wounds that Can be Treated by Light Therapy

Since wounds are of different types, wounds can be open or closed wounds. According to reports, LED light therapy can treat non-healing wounds, i.e., that doesn’t heal after 4 weeks. People with the following types of wounds can be healed from LED light therapy:

• Diabetic ulcers

• Venous ulcers

• Pressure ulcers

• Non-healing surgical wounds

• Serious burns

• Oral sores from chemotherapy/radiation

• Metabolic-disease-related wounds

• Wounds that repeatedly break down

How Red and Near-Infrared light Works for Wound

Light therapy a broad range of light having different wavelengths. Red light (620 nm — 680 nm) is visible red light, whereas Near-Infrared light (700nm — 1100nm) is invisible. Many studies reported that biologists have found that treating the cells with near-infrared light can grow 150% to 200% faster than cells not stimulated by light.

Biologically the Near-Infrared light boosts microcirculation and formation of new capillaries at the wound section.

Infrared light rays increase cellular energy that speeds up any healing process and penetrates deeper into the skin. As a result, the wound section receives more oxygen and nutrients to naturally help with the wound's healing process.

The light nurtures the lymph system activity. This assists with the detoxification process of the wound without overtaxing the lymph system and prevents lymphedema. The near-infrared rays also clean up the dead or damaged cells, making a clear blood circulation path.

Another benefit of Infrared therapy is that it helps release ATP (raw cellular energy), which gives energy to the damaged cells in the wound to heal better and faster (study).

Not only this, the studies have shown that the wound size also decreased by up to 36%.

Putting the Light on Psoriasis

Psoriasis is an autoimmune inflammatory skin disease where the skin cells build up and form scales and itchy, dry patches over the surface. It is a misunderstood skin condition. The misbelief is that it not treatable and affects a particular gender or at a certain age. However, it can affect both men and women equally, and more than 5 million adults deal with this skin disorder — which is about 2% of the U.S. population.

Another common misconception is that it is contagious and can spread from one person to another. Well, Psoriasis is an immune system problem in which your immune system does not work as it should normally do.

Light Therapy: The Advanced Way

With some options available for Psoriasis, light therapy is one of the oldest, safest, effective, convenient, and highly preferred treatment by dermatologists. It has been widely used to treat stable psoriatic lesions, including different parts like the trunk, scalp, arms, and legs, and partial nail psoriasis. The treatment of light therapy is available in a variety of light with different mechanisms of action. Based on the bandwidths, the varied versions includes ultraviolet B (UVB), psoralen ultraviolet A (PUVA), pulsed dye laser (PDL), photodynamic therapy (PDT), intense pulsed light (IPL), light-emitting diodes (LED), etc.

How it Works

Light therapy has a very long history of dermatological benefits. Psoriasis happens when the skin cells there is an abnormal production of skin cells. Light therapy works by slowing down the excessive production of skin cells on the epidermis layer. This reduces plaque formation. It also reduces inflammation and limits the growth of skin cells by affecting the functioning of the DNA.

Many clinical studies and researches have displayed positive and effective result in the treatment of various types of Psoriasis like –

  • Small areas of stubborn, thick plaque psoriasis
  • Palmoplantar psoriasis (on hands and feet)
  • Nail psoriasis
  • Scalp psoriasis

Why do Dermatologists Prescribe Light Therapy?

Light therapy treatment can:

  • Slow down the growth of abundant skin cells
  • Repress the functioning of an overly active immune system
  • Reduce inflammation and allow the skin to heal itself
  • Reduce or eliminate the dry and itchiness

Light Therapy Mechanism

Light therapy can be delivered on any affected skin areas such as the hands or scalp, or across their whole body. But proper care and protection are given to the skin areas, such as the eyes and genitals, before treatment.

The treatment doesn’t work in on-go. Several sessions are required as the effect is gradually seen in patients. The treatment requires multiple sessions where the amount of light is gradually increased per session. The light exposure is not instant and varies for a different duration depending on the skin condition severity.

The sessions give proper time to heal the skin. Usually, the sessions go from two to three months. We need to understand the fact that every person’s skin reacts to light therapy differently. Hence, how much improvement one sees in their psoriasis symptoms and how long those benefits last depends totally on their system.

Now the time has changed, and technology has brought more convenience in getting the treatment. Kaiyan Medical provides you numerous products that you can use at your home and enjoy your daily activities without getting disturbed. Break the old and mainstream treatments and adopt effective light therapy to let your skin and life heal completely!

The Effect of Green & Red Light Therapy on Hearing

Low-level laser therapy

Low-level laser therapy (LLLT) has been practiced for over 20 years in Europe and has been introduced in the United States as a treatment for pain and postsurgical tissue repair. It has been proposed that laser energy in the red and near-infrared light spectrum may aid in the repair of tissue damage. A proposed mechanism for this therapeutic effect is the stimulation of mitochondria in the cells to produce more energy through the production of adenosine triphosphate.

Studies in humans have investigated the effects of LLLT on both hearing loss and tinnitus, with equivocal results. Some studies have found an improvement in hearing thresholds and tinnitus symptoms.

The Subjects

A total of 35 adult subjects were enrolled in the study. Two subjects withdrew from the study due to loss of interest and/or scheduling difficulty. The data from three additional subjects were not included in the analysis. One subject yielded unreliable audiometric and speech understanding data, speech scores could not be obtained from one subject with a profound hearing loss, and calibration problems compromised data from the third subject. Data from the remaining 30 subjects were included in the analyses. The experimental protocol was approved by the Institutional Review Board of The University of Iowa, and written informed consent was obtained from all participants.

The Device

An Erchonia EHL laser was used to provide the laser stimulation. The device was a portable unit that consisted of a hand-held probe and a main body. The probe contained two laser diodes. One diode produced light in the green part of the visible light spectrum (532 nm wavelength), and the other diode produced light in the red part of the visible light spectrum (635 nm wavelength). Both diodes produced energy levels of 7.5 mW (class IIIb). The laser beams from both diodes were dispersed through lenses to create parallel line-generated beams, rather than spots. A second Erchonia EHL device served as the placebo. It was identical to the treatment device, except that the laser diodes were replaced with nonfunctioning standard light-emitting diodes.

The Groups

The study used three groups: treatment, placebo, and control. Subjects were pseudorandomly assigned to one of the three groups.

Initial group assignment was random with occasional adjustment to ensure that the three groups were similar in terms of number of participants, female/male ratio, mean age of participants, and mean pure-tone audiometric thresholds. The treatment group received the laser treatment protocol using the functional laser device. The placebo group also received the laser treatment protocol, but using the nonfunctioning laser device. The control group made similarly timed visits to the laboratory but received no real or feigned “treatment.” The study used a repeated-measures design, with each subject taking a battery of pretests, followed by treatment followed by a battery of posttests.

Analysis

Data were obtained from both ears of each subject. Since no obvious differences were seen between left and right ears, data from both ears were combined in the following analyses. Strictly speaking, this likely violates the statistical assumption of independent sampling, since the test results from left and right ears of a single subject are likely to be highly correlated. None of the statistical tests used in the analyses are robust to the assumption of independent sampling, and the effect of including both ears is likely to be that of artificially increasing the sample size, making it more likely that a statistically significant result will be found. All statistical tests were conducted using a significance level of .

Conclusions

No statistically significant effect of LLLT on auditory function was found, as assessed by pure-tone audiometry, speech understanding, and TEOAEs in this test. Additionally, no individual subjects showed any clinically significant change. It remains possible that other methods of LLLT could have an effect on hearing. The type of device used was not the best one for this type of study. Further research elucidating the anatomic and physiologic bases for therapeutic effects of LLLT on hearing are needed before further clinical testing is warranted.

How to Prevent Jet Lag with Light Therapy

How to Prevent Jetlag with Light Therapy Treatment

Globetrotters know flying across time zones can be all fun and games until headaches start to kick in, sleep cycles get disturbed, and frequent moments of inappetence prevents them from enjoying even the most sumptuous local cuisine. If you’ve had any of these unfortunate events disturb your travel plans and work productivity, you’ve most likely experienced a jet lag.

What is Jet Lag?

Jet lag, also known as jet lag disorder is our body’s reaction to abrupt changes in new environments that are two or more time zones ahead/delayed. This can affect even the most seasoned flyers like pilots and business travelers.

What causes Jet lag disorder?

Your body has a clock system called circadian rhythm that schedules your body for its sleep and wake up time. Your circadian clock is synced depending on your original time zone.

Jet lag is caused by a temporary discoordination with your circadian clock and your new time zone or sleep-wake schedule. This is why when you expose your body to abrupt schedule changes, its normal functions related to sleep, coordination, and gastrointestinal processes are disrupted. While your mind may be ready to fly west, your body may still be stuck home and is still hours ahead.

Treating Jet Lag with Light Therapy

Jet lag can take days, weeks, or longer to improve, which may affect daily activities. In addition, although jet lag may be a temporary disorder, frequent exposure also poses significant long-term risks such as disturbances in menstrual cycle, cognitive defects, and temporal lobe atrophy.

One popular and effective treatment for jet lag disorder is Light therapy. Light therapy has been considered as a popular and effective treatment for jet lag disorder and has been backed by research since 1980.

Your body clock is largely influenced, among other factors by light, which is indicative of the rising and setting of the sun. This means that adjusting to a new time zone also means adjusting to a new daylight-night time and awake-sleep schedule.

Essentially, light therapy assists your brain and body in adjusting to a new time zone by conditioning yourself to light at an appropriate time. This allows your normal body functions to be in sync with your new schedule. By regulating light exposure, you can adjust faster with new conditions.

Studies show that exposure to light therapy helps people adjust their circadian clocks to new time zones more efficiently and effectively. Treatment of jet lag by Light therapy involves an exposure to natural or artificial light such as red light therapy.


How does Red light therapy work?

Red light therapy is a non-invasive, quick and easy treatment for jet lag that brings concentrated natural light to your body cells in order to condition it for a new day-light schedule. Red light therapy emits natural light that can boost cell energy without the putting your body at risk of the damaging UV rays from the sun.

If you travel westwards, you can use Red Light in the evening to help you adjust to a later time. On the other hand, if you travel eastwards, you can expose yourself to red light in the morning in order to acclimate your body to an earlier time zone.

Kaiyan produces high-quality Red light therapy home devices that utilize medical-grade LED (Light-emitting Diode) in order to produce a natural red light that is ideal for adjusting to new time schedules.

The great thing about this device is that, if you often work away from sunlight, this indoor light therapy device can be a convenient way to adopt your circadian clock to a new time zone. Check out our top picks for the best FDA-cleared light therapy masks.

Experiencing jet lag may be the ultimate bummer for travelling, but sufficient knowledge and proper treatment can keep you away from ruining your travel plans and goals.

The Brain in Our Skin

Dr. Claudia Aguirre which has a Ph.D. in neuroscience from USC and travels the world lecturing on a broad range of topics from neuroscience to skin care has been researching the power of the skin and its connection with the brain.

The skin is highly innervated and intricately connected to the brain and central nervous system, just as other sensory organs are. Dr. Claudia Aguirre is discovering that the skin has a lot of neuro potential, or neuroplasticity, that has gone unrecognized. For example, just as our eyes have receptors that transduce light photons into signals to the brain that we process as vision, we’re discovering that our skin also has light receptors. Although we don’t yet know how they work, we speculate that they might be signaling the brain to make systemic changes that affect the full nervous system. Similarly, olfactory receptors in the hair follicles, just as we do in the nose.

Examples

Another example is touch, for which our skin is the primary sense organ. Skin is also our largest organ, which gives us a clue as to how important touch is. Different receptors in the skin can tell us not only whether what we touch is hot or cold, rough or smooth. Skin can even sense the intention behind the touch. A gentle touch feels much different than an aggressive one. We can tell whether the person giving us a massage is paying attention or whether they’re distracted. Moreover, different kinds of touch elicit different biochemical and hormonal responses, which have systemic results. A hug or kiss stimulates the release of oxytocin, the bonding hormone, through the bloodstream, while a punch or shove will release adrenaline and cortisol. All of these capabilities are what we say by the hidden brain in the skin.

Nervous System

The skin is connected to the nervous system; it’s connected to the endocrine system. The skin is impacted by our emotional states and, conversely, our skin can impact how we feel about ourselves. Cultural stress and anxiety can trigger or aggravate many skin conditions—from acne to eczema to herpes, psoriasis, and rosacea. Conversely, a disfiguring skin condition can trigger stress, anxiety, depression, and even suicide. Chronic, generalized anxiety can create chronic inflammation and exacerbate inflammatory skin conditions, such as the ones mentioned previously. Chronic stress can result in chronic anxiety, hypervigilance, poor sleep, and a whole cascade of effects resulting in a constant breakdown of tissues and organs, including the skin. There’s a whole new field of medicine being developed called psychodermatology, which is the study and treatment of the psychological component of skin conditions. Better understanding of the neuropotential of skin also opens the possibility of whole new avenues of treatment with light therapy for many of our chronic conditions.

In Kaiyan Medical we have understood that neuroscience should absolutely be part of the conversation about skincare and beauty because the brain and the skin are intimately connected. Skincare is important not only for the skin, but also the brain. That's why we keep developing light therapy devices for skin and brain. In Kaiyan we always recommend to listen for all the little signs that your skin tells you that you tend to ignore. You get a rash, and you brush it off: “Maybe it’s just dry out. Maybe I need to switch creams.” But if it occurs repeatedly, you need to look more closely and ask, “What could my skin be trying to tell me?” Are you repressing emotions? Is there a relationship issue you’re avoiding? Is there some other life circumstance that’s “gotten under your skin”? The body has a wisdom we should listen to.

Light Therapy - Color Meaning

Introduction to Color Light Therapy

Color Light therapy is based on the idea of restoring balance by applying color to the body. Its history is rooted as far back as the Mayan culture.

In India, Ayurveda, an ancient form of medicine practiced for thousands of years, is based on the idea that every individual contains five elements of the universe that are present in specific proportions unique to each individual, including their personality type and constitution. When these elements are out of balance, Ayurveda works with the energies inherent in the colors of the spectrum to restore this balance.

In ancient Egypt the art of healing with color was founded in the Hermetic tradition, the Ancient Egyptians and Greeks used colored minerals, stones, crystals, salves, and dyes as remedies, and painted treatment sanctuaries in various shades of color.

In China, traditional Chinese medicine incorporates color to be associated with each organ and elemental system. This healing method looks at the idea that every individual is a balance. The first color wheel was invented by Sir Isaac Newton. He split white sunlight into red, orange, yellow, green, cyan, and blue. He then joined the two ends of the color spectrum together to show the natural progression of colors.

Light Therapy has been valued throughout history as a remarkable source of healing. Today, the therapeutic applications of light and color are being investigated in major hospitals and research centers worldwide. Results indicate that full-spectrum, ultraviolet, colored, and laser light can have therapeutic value for a range of conditions from chronic pain and depression to immune disorders.

Wellness Benefits

Light Therapy has been reported, as part of a healthy lifestyle, to temporarily reduce swelling, relieve pain, decrease inflammation, accelerate open wound healing and greatly reduce overall recovery after medical/surgical procedures. Patients have demonstrated an increased range of motion, decreased muscle tension and spasm, and improved circulation.

Rejuvenating LED light therapy can be used for temporary pain management such as joint and back pain, sore or torn muscles, sprains, arthritis, post-surgical scars, burns, wounds, and more. When used with infrared technology, light therapy (phototherapy) is one of the most effective and non-invasive ways to improve overall wellness.

Light therapy is also used to temporarily relieve Seasonal Affective Disorder (SAD). SAD affects individuals when the lack of sunlight results in seasonal depression. Phototherapy helps with SAD by resetting the internal biological clock (Circadian rhythms), helping individuals sleep better, and regulate their mood. Even companies, such as GE and Philips, have created phototherapeutic products to improve and regulate mood.

Cosmetic Benefits

Light therapy is also a growing treatment for anti-aging. Many individuals have seen a temporary reduction in the appearance of fine lines, wrinkles, crow’s feet, and age spots.

Light therapy is “effective at improving the appearance of the face, neck, and chest by reducing the signs of aging, wrinkles and age spots”, says Web M.D. Combined with infrared therapy, LED phototherapy can be a great way to revitalize skin.

Healing With Color

Color is light split into different wavelengths vibrating at different speeds and at different frequencies. Objects that ABSORB all wavelengths and DO NOT reflect are black in nature. Objects that REFLECT all wavelengths and DO reflect are white in nature. Between black and white lies COLOR. Colors are wavelengths of energy that, to us, appear as color because of the potential and capabilities of the object to either absorb or reflect the energy.

Red Light

In the early 1990s, RLT was used by scientists to help grow plants in space. The scientists found that the intense light from red light-emitting diodes (LEDs) helped promote the growth and photosynthesis of plant cells.

The red light was then studied for its potential application in medicine, more specifically to find out if RLT could increase energy inside human cells. The researchers hoped that RLT could be an effective way to treat the muscle atrophy, slow wound healing, and bone density issues caused by weightlessness during space travel.

You may have heard of red light therapy (RLT) by its other names, which include:

  • photobiomodulation (PBM)
  • low-level light therapy (LLLT)
  • soft laser therapy
  • cold laser therapy
  • biostimulation
  • photonic stimulation
  • low-power laser therapy (LPLT)

Red is called “The Great Healer”. So far is the most popular light therapy. To wind down before bed, use red light. “The color signals that it’s night, which may encourage the body to produce melatonin,” says Michael Breus, Ph.D., an advisory board member for SleepScore Labs.

Red light can also improve your workout. Just one to five minutes of exposure to red and infrared light right before exercise boosted strength and prevented soreness, says Ernesto Leal-Junior, Ph.D., the head of the Laboratory of Phototherapy in Sports and Exercise at Nove de Julho University in Brazil. “Certain wavelengths of red and infrared light-660 to 905 nanometers-reach skeletal muscle tissue, stimulating the mitochondria to produce more ATP, a substance that cells use as fuel,” he says.

Green Light

Green is the universal healing color. Originally, the color of love. Green is midway in the color spectrum; therefore, it contains both a physical nature and a spiritual nature, in equal balance and in equal harmony.

Gazing at green light can reduce chronic pain (caused by fibromyalgia or migraines, for example) by up to 60 percent, according to a study in the journal Pain, and animal studies have shown that the beneficial effects can last up to nine days. “Looking at green light seems to lead to an increase in the body’s production of enkephalins, pain-killing opioid-like chemicals. And it reduces inflammation, which plays a role in many chronic pain conditions,” says researcher Mohab Ibrahim, M.D., Ph.D.

More studies are needed before doctors can make recommendations on how and how often to use green light to treat migraines and other pain, and Dr. Ibrahim says you should see a physician before trying to treat yourself at home. But at this point research indicates that exposing yourself to an hour or two every night-either by using a green light bulb in a lamp or by wearing glasses fitted with tinted optical filters-may decrease migraines and other types of chronic pain

Helps to treat and prevent hyper-pigmentation by inhibiting the production of excess melanin which then prevents it from traveling to the surface. It will help break up the melanin clusters that are already on the surface.

Yellow Light

Yellow helps awaken mental inspiration arousing a higher mentality. Thus, it is an excellent color for nervous or nerve-related conditions or ailments; fueling the solar plexus. Yellow has a very enriching effect upon the intellect. Yellow can be used for conditions of the stomach, liver, and intestines. It can help the pores of the skin by repairing scarred tissue. These rays have an alkalizing effect which strengthens the nerves. Awakening, inspiring, and vitally stimulating the higher mind promoting self-control. Typical diseases treated by yellow are constipation, gas, liver troubles, diabetes, eczema, and nervous exhaustion. Providing clarity of thought, increasing awareness, stimulating interest, and curiosity yellow energy is related to the ability to perceive or understand.

The yellow is used for treating redness, flushing, irritation, and Rosacea. It may also reduce the appearance of the tiny blood vessels on the nose and face.

Blue Light

Blue light therapy technology is an additional option for the treatment of acne. Research has shown in-office and at-home systems produce positive results.

“Blue light therapy effectively helps alleviate this common skin condition affecting 50 million Americans and 94 percent of all females, according to Judith Hellman, MD, a board-certified dermatologist, in practice in New York City. Dr. Hellman, who practices medical dermatology and specializes in dermatological surgery, laser surgery, and anti-aging skin treatments, explains how the blue light treatment system works for acne, its uses, and her clinical experience with the technology.

Cyan Light

It is used as a gentle acne treatment to control oil production in the skin as well as reduce inflammation. It also promotes the synthesis of protein and collagen.

Orange Light

Orange has a freeing action upon the mind, relieving repression. Because orange is a blend of red and yellow, it combines physical energy with mental wisdom, inducing a transformation between lower physical reaction and higher mental response. Thus, it is often referred to as “The Wisdom Ray.” Orange is warm, cheering, and non-constricting.

Through orange, we are able to heal the physical body (red) and, at the same time, induce within the mind (yellow) greater understanding. Orange helps assimilate new ideas. Orange is the best emotional stimulant, helping to remove inhibitions paving independent social behavior. Bring joy to your workday and strengthen your appetite for life. Orange aids in repairing inflammation of the kidneys, gallstones, menstrual cramps, epilepsy, wet cough, and all sinus conditions.

Purple Light

Violet is the last color we can see before light passes on to ultra-violet. Violet purifies our thoughts and feelings giving us inspiration in all undertakings. The violet energy connects us to our spiritual self bringing guidance, wisdom, and inner strength and enhances artistic talent and creativity. Leonardo da Vinci proclaimed that you can increase the power of meditation ten-fold by meditating under the gentle rays of Violet, as found in church windows.

Light therapy uses colors for their proposed wellness abilities in treating emotional and physical disturbances. Light therapy is based on the premise that different colors evoke different responses in people. For example, some colors are considered to be stimulating, whereas others may be soothing. Color therapy has been suggested for many uses, based on tradition or on scientific theories. Consult with a health care provider before using color therapy for any use.

Infrared Light

Infrared light penetrates to the inner layers of the skin at about 2 to 7 centimeters deep. Hence, it reaches the muscles, nerves, and even the bones. Many studies have shown that a frequency of infrared light, with wavelengths from 700 to 1,000 nanometers, is best used for healing inflammatory conditions.

The use of electricity for healing purposes began in 2,750 BC when people used electric eels to give electric shocks. Electricity and magnetism were used in people with just little success. However, in 1975, transcutaneous electrical stimulation (TENS) was developed to treat chronic pain. It was not until recently that infrared therapy was developed to improve wound healing, reduce the pain caused by arthritis, boost endorphin levels, and bioactivate neuromodulators.

Infrared therapy technology allows people to harness the benefits of the sun, without being exposed to harmful ultraviolet rays. Also, infrared therapy is safe and effective, without adverse side effects. As a matter of fact, infrared light is safe and is used even for infants in neonatal intensive care.

Infrared light is absorbed by the photoreceptors in cells. Once absorbed, the light energy kickstarts a series of metabolic events, triggering several natural processes of the body on a cellular level.

Kaiyan Medical

In Kaiyan, we are in love with light therapy. We believe in the natural balance in our bodies. We develop devices such as the Aduro mask which will provide you with the full range of color light therapies.

5 Biohacking Techniques

What is Biohacking?

Biohacking is the practice of changing our chemistry and our physiology through science and self-experimentation to energize and enhance the body. It’s a broad definition, but that’s also because the concept is constantly evolving. It includes implementing lifestyle and dietary changes that improve the functioning of your body, as well as wearable technology to help you monitor and regulate physiological data. It can even run to extremes such as using implant technology and genetic engineering.

The possibilities are endless, but they are all rooted in the idea that we can change our bodies and our brains, and that by doing so we can ultimately become smarter, faster, and better as human beings.

Start biohacking your body by using wearables like the FitBit or the Apple Watch to track the way you operate. You could also start experimenting with the power of music in your everyday life and adopting a sustainable healthy diet. But if you’re ready for something new, and something different, consider one of these non-invasive methods from our biohacking guide:

Biohack Tip 1: Red Light Therapy

Have you ever spent a lot of time indoors and begun to feel… off? Our bodies and brains need light to function at their best. Not only does the sun give us an important dose of vitamin D, but it helps us in a number of other physiological and emotional ways. Let’s look a little closer – specifically at the light wavelengths between 600 and 900 nanometers (nm). How does this range of light waves impact us and how can we use it to biohack the body?

Studies have shown that your body responds particularly well to red and near-infrared wavelengths, which range from 600 to 900 nm. This particular range of light waves is absorbed by the skin to a depth of about 8 to 10 millimeters, at which point your mitochondrial chromophores absorb the photons. This activates a number of the nervous system and metabolic processes.

In plainer terms, red light therapy has become an increasingly popular form of biohacking used to treat a number of conditions. It has been proven to relieve pain, reduce inflammation, and restore mood. And because it is a non-invasive and non-chemical treatment, it’s not as intimidating as other forms of biohacking.

Biohacking Tip 2: Functional Music

With over 100 billion neurons that are constantly using electricity to talk to each other, your brain is like Grand Central Station. If everyone is chattering loudly at the same time, it can be tough to concentrate on what you need to get done. That’s where music biohacking comes in. Brain activity can be measured in a wave-like pattern and determines if you feel alert, sleepy, relaxed, or stressed. Things that can affect your brainwaves include the activity you are currently performing, how much restorative rest you’ve had, and what you’ve just eaten or drank.

One of the most reliable ways to change your brainwaves is through a consistent sound wave. Audio entrainment, a form of music biohacking, uses binaural beats and tones to synchronize with your brain waves and induce a meditative, relaxed state. You can access programs developed specifically for your own brain and the activities you want to accomplish at Brain.fm. If you’re not ready to go that far, you can still change your mood and mindset by queuing up your favorite playlist and listening while you work out, cook breakfast, or commute to work.

Biohacking Tip 3: Osteostrong

We talk a lot about cardiac health. After all, heart disease is the #1 killer of women in the United States. Everyone needs to be aware of cardiovascular diseases and how to protect themselves as best they can. As a culture, we also talk a lot about skin health – slathering on sunscreen as part of our daily routine and supplementing our diets with collagen-boosting foods. Weight loss, inflammation, memory, GI health, and how an unhealthy diet and lack of exercise can prematurely age you – these are all at the forefront of our minds. But how often do we think about the health of our bones?

A decrease in bone health creeps up on you and most people are unaware of how bone density changes over time. Roughly up until the age of 30, men and women actually build more bone than they lose, so we are constantly strengthening our bones and working on bone density. But when we hit our mid-30s, things change. And if you’ve passed that benchmark, you may have felt that shift.

After reaching their mid-30s, women lose about 2% of bone density every year, and that continues for a few years following menopause. This leaves women with a high likelihood of experiencing osteoporosis.

So what do you do? Consider trying OsteoStrong, a non-pharmaceutical way of improving bone density, strength, and balance as one of your biohacking techniques.

According to OsteoStrong’s website, research indicates that the stimulus required to activate the growth of healthy bone tissue is 4.2 multiples of body weight. However, this level of force would be exceptionally difficult to achieve on your own. That’s why OsteoStrong utilizes the Spectrum System, which is part of a new category of devices called the Robotic Musculoskeletal Development System (RDMS).

Biohacking Tip 4: Gratitude

How we view life has a huge effect on our moods, how we treat others, and our general levels of fulfillment. When you have an abundance mindset, you’re consistently grateful for everything that comes your way and is always focused on the positive. Have a hard time adopting this type of perspective? Changing your mindset is really about nothing more than practice. You need to consistently refocus your brain to see the positive in every situation until it becomes second nature. These biohacking techniques and tools can help:

  • A gratitude journal in which you write three to five things you’re grateful for helps you reframe the day to focus on the positive and reflect on all the good things that happen to you.
  • Take a gratitude walk where you give thanks and send positive energy to every living thing you see. If you walk to work or take a morning jog, you can easily incorporate this into your normal routine.
  • Write a weekly letter of gratitude to someone who has helped you or who means a lot to you. It could be a family member, a long-lost friend, or even a coworker who always remembers to stock your favorite coffee.
  • Begin the day with a ritual, such as meditating, and set an intention to be grateful for all you encounter.
Biohacking Tip 5: Supplements

Exercising, eating right, and developing the right mindset are important steps to unlocking an extraordinary life. Biohacking helps you take this to the next level by incorporating supplements that improve focus, increase energy, and help your body benefit from the most bioavailable forms of nutrients available.

We often don’t get all the vitamins and minerals we need to keep us at peak performance. High-quality supplements in the form of pills, shakes, bars, or drinks can fill the nutritional gap and help boost performance, detoxify our systems, and achieve daily energy.

Tony has created a variety of health supplements, drinks, and bars that help you feel your best every day and make biohacking the body easy.

Red Light Therapy - 101

We are not just made of biochemical matter. We are charged energy beings, constantly interacting with the environment. Light plays a crucial role in this natural process. Comprehensive new research has unearthed a full new understanding of how our cells function optimally. Food is not the only way we obtain energy; the light also charges us.

Science now shows your body operates like a battery. Certain wavelengths of sunlight power it, and your general health is determined by your ability to receive and maintain a charge. This is what light therapy is about.

What is Red Light Therapy

Light at certain wavelengths is scientifically proven to interact with the body in beneficial ways.

Red light, comprising both red and near-infrared wavelengths, is a unique healing part of the electromagnetic spectrum, and it is one of the most natural ways to charge the body. It is now used as a new form of therapy under the umbrella term Photobiomodulation(PBM)

Red light wavelengths ranging from 600–680nm. Red light boosts the formation of collagen and elastin and assists in cell communication. It penetrates superficially and can be used for skin conditions.

Near-Infrared wavelengths ranging from 750–850nm. NIR stimulates healing, increases mitochondrial function, and improves blood flow and tissue oxygenation. It penetrates deeper into the body.

A high-quality home device like those produced by Kaiyan uses medical-grade LEDs to shine natural red and near-infrared light on your body. Like the wavelengths of light your body needs from natural sunlight, without the heat or UV rays that cause sun damage and without the need for sunny weather. Check the list of best light therapy masks.

How to Recharge your Body

Electric charge is a fundamental property of the body. The surfaces in our bodies — such as membranes, proteins, and DNA — are all charged, negatively or positively, depending on whether they lose or gain electrons.

At the core of your body’s power to heal itself are sub-cellar organelles called mitochondria. The number of mitochondria in a cell varies widely by organism, tissue, and cell type and are concentrated in organs with high energy demands such as the brain, heart, liver, skin, and muscles.

This is because mitochondria generate most of the body's chemical energy supply via the ATP (adenosine triphosphate). They also regulate various other tasks, such as signaling, cellular differentiation, and maintaining control of the cell cycle and cell growth. This is why they are often referred to as the powerhouse of the cell.

Mitochondria
  1. LED light at a wavelength from 600–680nm(red) and between 810–850nm(infrared) is delivered to the tissue via the red light therapy device.
  2. The light enters the cell’s mitochondria and is absorbed by the chromophores, including the protein cytochrome c oxidase(CCO) and EZ water, increasing its activity.
  3. As a result of this highlighted activity, three molecules are affected. Adenosine Triphosphate(ATP), Reactive Oxygen Species (ROS), and Nitric Oxide (NO).
Water

Approximately 70% of our body weight and 99% of our bodies ’ molecules are made of water, and this water is in a charged state.

Recent research by Prof Gerald Pollock of the University of Washington has shown that water adjacent to a cell or mitochondrial membrane is so-called structured water. This is also called EZ (exclusion zone) water because it creates a separation of charge. Positive proton is excluded and pushed to the bulk water, and a lattice-like negatively charged water for near the membrane. This increases the voltage across the membrane—this charge separation of water in the body functions as the positive and negative poles of a battery.

What Does “Red Light Therapy” Mean?

As a term, “red light therapy” refers to treatments from LEDs or cold lasers that deliver wavelengths of natural red and near-infrared light.

The term does not include white light, blue light, or blue LED masks, and it is not the same as full-spectrum light. Some people may include infrared or far-infrared wavelengths along with red light therapy, but those are typically used in dry saunas because of their ability to produce heat. Red light therapy does not rely on heat, a major difference between natural light treatments and heat-based modalities like an infrared sauna, traditional sauna, or other heat therapy type.

Generally, “red light therapy” describes natural light treatments that deliver the same therapeutic red and near-infrared wavelengths as natural sunlight. This differs from artificial light treatments like tanning — or bright light therapy from light therapy lamps, lightboxes, or happy-light if you’re interested in natural light treatments for seasonal affective disorder.

The following terms may also call red light therapy: RLT, photobiomodulation (PBM), phototherapy, LED therapy, LED light therapy, infrared therapy, low-level laser therapy, or low-level light therapy (LLLT).

A Multilevel Treatment

Red light therapy works on multiple levels in the body.

Molecular

  • Chromophores, cytochrome c oxidase, water, opsins
  • Retrograde mitochondrial signaling
  • Light-sensitive ion channels
  • Adenosine triphosphate ATP
  • Reactive Oxygen Species ROS

Calcium

  • Heat-shock proteins
  • Melatonin
  • Brain-derived neurotrophic factor

Systemic Effects

Red light therapy affects multiple bodily systems:

Fascia

The fascia is a complex web of sensitive and highly interconnected connective tissue beneath the skin that attaches, stabilizes, encloses, and separates muscles and other internal organs.

Fascia is primarily made from hydrated collagen-Protein chains in a triple helix formation surrounded by water, with a capacity to generate an electric charge in response to applied mechanical stress (piezoelectric).

The bio-electrical nature of the collagen-rich matrix is the key to understanding how pathological changes in one part of the body may cause a cascade of “remote effects” in seemingly unrelated areas and organ systems. The fascia is the long-overlooked but absolutely crucial interconnecting organ of the human body. The therapeutic effect of red light energy can be carried through the fascia network to other parts of the body where it is needed. This is turn, elevates the body’s capacity to communicate via this charged matrix in a positive feedback loop.

The well-known energy meridians of traditional Chinese medicine may actually be low resistance pathways operating through the fascia, conveying energy to the rest of the body.

Gut-Brain Axis

The gut-brain axis links the emotional and cognitive center of the brain with peripheral intestinal functions. Red light energy applied to the abdomen area can therefore influence mood and neuropsychological issues via several mechanisms:

  • Reduction in bowel inflammation and gut spasms.
  • Stimulation of neurotransmitters and hormones in the gut, including serotonin, leptin, and ghrelin.
  • Modulation of the micro-biome. The gut microbes are sensitive to light energy and respond to light energy with differences in growth, migration, and proliferation of the different species.
  • The increasing availability of neurotransmitters activates the brain’s immune system, increases blood flow, and removes toxins.
  • Increased blood circulation and reduced blood pressure leading to a reduction of anxiety and brain fog.
  • Modulation of the vagus nerve, one of the biggest nerves connecting the gut and brain. This plays an important role in stress and social communication, communicating motor and sensory impulses to every organ in the body.

Immune System

Beaming red light and near-infrared light onto cells creates a short, low-dose metabolic stress that builds up the cells' anti-inflammatory, anti-oxidant, and natural defense systems, making the body stronger and more resilient to infections.

This is the concept of hormesis; safe, low-level exposure to stressor results in increased resistance to illness. Red light has been shown to influence the immune response in several ways:

  • Activation of the mast cells leading to the movement of leukocytes and reduced inflammation.
  • Mast cell DE-granulation and the release of pro-inflammatory cytokines.
  • Increased infiltration of the tissues by leukocytes.
  • Enhanced proliferation, maturation, and motility of fibroblasts
  • Increased production of fibroblast growth factor.
  • Lymphocyte activation and proliferation.
  • Macro-phages activated to act as phagocytes.

Circulatory System

Red light therapy has been shown to aid the circulatory system's functioning and increase the micro-circulation of blood, one of the most recognized and well-documented effects of this therapy.

Red light stimulates the formation of new capillaries carrying more oxygen to the body.

A good oxygen supply is intricately involved in numerous biological processes, including cell proliferation, angiogenesis, and protein synthesis, required to restore tissue function and integrity.

Increased circulation allows for waste products to be carried away more effectively. It triggers and heightens the body’s own scavenging process for and ingesting degenerated cells for clean-up.

In fact, increased micro-circulation of blood is thought to be the most vital function for healing the body for almost every illness. For general well-being, Nutrient-rich blood and efficient waste removal is strongly linked to good health.

Nervous System

The nervous system is a complex electrical system, including the brain and spinal cord. It collects, processes, and responds to the input of energy-be it light, sound, heat, or pressure — and it relays these messages to the brain and around the body.

Red light energy affects the nervous system in several crucial ways:

  • Myelination of fibers and a better lamellar organization of the myelin sheath.
  • Improvement of electrophysiological function.
  • Facilitation of neural regeneration.
  • Release of growth factors.
  • Increase of vascular network and collagen.
  • Faster regeneration of nerve lesions and functional improvement of damaged nerves.

The peripheral nerves can be damaged by infection or high sugar levels in the case of diabetic neuropathy.

Red light therapy is being explored as a promising drug-free therapy for all kinds of nerve damage.

Stem Cells

At the frontier of science, red light therapy shows huge promise in current research to stimulate the growth of stem cells in the body and maximize the effect of stem cell implantation for a wide variety of medical purposes.

Therefore, red light may be useful after surgery to stimulate stem cells to aid the repair of tissues and possibly organs.

Light at certain wavelengths has also been shown to coax stem cells to repair teeth, so red light therapy could soon revolutionize dental treatments. Indeed, some progressive dental clinics now offer red light therapy as an alternative to conventional drug and drill treatments.

Red light therapy has been shown to stimulate mesenchymal stem cells in the bone marrow to enhance their capacity to infiltrate the brain.

This has implications for healing degenerative conditions such as dementia, Alzheimer’s, and Parkinson’s disease , currently lacking any orthodox treatment solution.

Where Did Red Light Therapy Come From?

Red light therapy has become a popular natural health intervention, both in professional settings and with home devices.

Light therapy technology has been used in medicine for decades, and NASA experimented with red light therapy use in space in the 1980s and 1990s. In the last 10–20 years, red light therapy has become more widely used thanks to breakthroughs in LED lighting technology that have made affordable home devices possible.

Major advances in clinical light therapy research, and increased public interest in natural health technologies, have also contributed to the growing use and popularity of red light therapy.

In 2016, Kaiyan Medical was the first red light therapy manufacturer to offer affordable, medical-grade devices to consumers for convenient, at-home use.

Relieve Pain And Discomfort

In humans, photobiomodulation is reportedly effective against various pain conditions, including mucositis, carpal tunnel syndrome, orthodontic pain, temporomandibular joint pain, neck pain, neuropathic pain from amputation, and menstrual cramps.

Red light therapy significantly reduces the severity of pain hypersensitivity while improving sensorimotor function.

These improvements are preceded by an anti-inflammatory microglia/macrophage cell population in the injury zone, thereby providing a lasting pain relief effect.

Red light therapy has been shown to yield effective pain relief via the modulation of multiple mechanisms:

  • Inhibitory cyclooxygenase and prostaglandins
  • Modulating nerve transmission
  • Increasing endorphins serotonin release
  • Stimulating metabolism
  • Activating peripheral opioid receptors
Repair Skin

Red light therapy is used for the rapid and safe healing of wounds from burns, surgery incisions, scars, diabetic neuropathy, ulcers, and bedsores.

Faster and better wound healing was one of NASA’s original findings and one of the key recognized uses for this technology. Red and near-infrared light promote beneficial effects during all four phases of the wound-healing process:

  • Coagulation
  • Inflammation
  • Migration
  • Remodeling

These processes are regulated by many growth factors connected with nitric oxide (NO) signaling release, which is modulated by light energy.

A major typical inhibiting factor for the body’s ability to recover from a wound is low oxygen flow. Therefore, the unique ability of red light to increase oxygen flow to the affected area has a massive effect on the healing process.

By reducing inflammation, oxygenation of the area, and formation of new blood vessels, a rapid healing process unfolds with less pain and scarring.

Red light energy may also reduce or prevent the need for pharmaceutical painkiller medication during the healing process.

Revive Immunity

If your body is energized on a cellular level and communication between the organ systems is efficient, your body will naturally develop disease resistance.

Your immune defense works to fend off bacteria and viruses all the time. Red light therapy boosts this system in several ways.

It releases nitric oxide and melatonin, which are involved in DNA repair and have a powerful antimicrobial effect.

It also works through a process known as hormesis. When red and near-infrared light is beamed into cells, it causes mild metabolic stress, which results in cells engaging their anti-inflammatory and antioxidant response.

In this way, the body is primed and ready to respond better to infections. Boosted immunity is also a natural consequence of other systemic effects of red light therapy.

Studies have shown a variety of benefits to the immune system:

  • Improved melatonin production
  • Improved antioxidant production
  • Increased micro-circulation enabling the transportation of immune cells.
  • Promotes activity in the lymph nodes
  • Increased NO levels
  • Better flow of neurotransmitters
  • Boosted collagen and elastin production
  • The more efficient function of cells and organelles
  • Boosts T cells pre-operatively
  • Improved thyroid function
Reduce Inflammation

Inflammation can be acute and topical ( short-lived, caused by accidents, sprains, and infections ), chronic and general ( long-term, caused by persistent conditions ).

While acute inflammation is a healthy physical healing response, chronic and general inflammation can be detrimental to health and often goes undetected.

Currently, the main treatment for inflammation in the body is NSAID or steroid drugs, both of which have side effects and disrupt the body's healing process. Red light therapy stimulates the body to activate its own healing mechanism, dramatically reducing the health risks associated with long term drug use.

Red light therapy works by decreasing the number of inflammatory cells, increasing fibroblast proliferation ( the cell that synthesizes the extra-cellular matrix and collagen ), stimulating angiogenesis ( the formation of new blood vessels ), and activating the body’s innate anti-inflammatory, antioxidant defenses.

The following conditions, associated with chronic and acute inflammation, are currently being investigated as highly promising targets for red light therapy.

  • Arthritis
  • Asthma
  • Sinusitis
  • Muscular sprains
  • Fibro-myalgia
  • Neuron inflammatory disorders such as Alzheimer’s
  • Irritable bowel syndrome and colitis
  • Rheumatic conditions
Regain Performance

Red light therapy has become a hot topic in sports and performance. Not only is it safe and non-toxic-it yields rapid and lasting results in many areas of application.

Besides the overwhelmingly beneficial effects on health overall, red light therapy supports muscle growth and repair by increasing the amount of ATP available, which allows for better performance and faster recovery.

Red light therapy used before training is known to prepare and strengthen the body and physical exertion to help with recovery.

Documented effects from red light therapy include:

  • Reducing DOMS ( Delayed Onset Muscle Soreness )
  • Greater endurance and performance
  • Improving sleep quality
  • Increasing sexual function and libido ( Including Testosterone )
  • Aiding weight loss
  • Boosting cognitive function
  • Reversing skin aging
  • Reducing cellulite
Red Light Therapy for Depression and Seasonal Affective Disorder

Seasonal affective disorder (SAD) is a type of depression that impacts at least 5% of Americans, especially in the winter months, when natural light exposure is lowest. SAD is also called seasonal depression, winter depression, or the winter blues.

Some people treat SAD symptoms with treatment options like bright white light therapies that mimic the sun’s light intensity at a bright time of day.

More researchers and physicians have used natural light treatments like red light therapy to help with natural light deficiency and the winter blues in recent years in conjunction with antidepressant medication and psychotherapy.

Who Uses Red Light Therapy?

In addition to the growing number of people using red light therapy devices in their home, red light therapy systems can be found in many professional and clinical settings:

Skincare Professionals: Red light therapy is a popular skin treatment among Hollywood celebrities for anti-aging, and it’s used by leading skincare professionals like estheticians and dermatologists to treat skin conditions and promote collagen production.

Health Practitioners: Red light therapy is an emerging subspecialty of medicine in a wide range of fields. From oncologists treating cancer side effects, to dentists reducing oral inflammation, to physicians treating mental health conditions, red light therapy is becoming more widespread in clinical practice.

Natural Health Experts: Leading voices in natural health and wellness like Dr. Sarah Ballantyne, Dave Asprey, and Ben Greenfield use red light therapy. So do Paleo and Keto health experts like Mark Sisson, Dr. Anthony Gustin, Luke Storey, and Robb Wolf.

Sports Medicine Pros: Light therapy companies work side by side with the National Association of Sports Medicine (NASM), and red light therapy is used to heal sports injuries by sports medicine professionals across the globe. Including the top trainers and doctors on the PGA Tour, like Dr. Troy Van Biezen and Dr. Ara Suppiah.

Elite Pro Athletes: Red light therapy is a popular training tool across pro sports, from NFL stars like Patrick Peterson, to UFC champs like Anthony Pettis, to gold medal gymnast Sanne Wevers.

Fitness & Training: World-class personal trainers like Lacey Stone and Jorge Cruise use red light therapy to both enhance performance and improve the muscle recovery process.

Supportive Cancer Care: The Multinational Association of Supportive Care in Cancer (MASCC) recommends red light therapy for the treatment of oral mucositis (OM), a common and debilitating symptom of cancer treatment.

The Sleeping Beauty Secret: The Red Light Therapy

Lack of sleep is a villain in America and Europe. Light intake is a big part of the problem. Over 65% of adults say they don’t get enough good sleep every week. Most people also don’t get nearly enough natural light for optimal health: the average American spends over 90% of their time indoors.

In addition to not getting enough natural light, people today are surrounded by artificial blue light from screens and overhead lighting. An overload of artificial blue light can cause headaches and make it harder to get to sleep and stay asleep. When we take in all that bright blue light from laptops, TVs, and phones, especially before we go to bed, our bodies get the signal that it's time to be awake, even if we're tired.

Melatonin is the naturally-occurring hormone that regulates sleep and wakefulness. Emerging research is showing that red light therapy treatments can help people produce more of their own, natural melatonin than exposure to other light sources like blue light. Red light therapy is natural light. It’s much less bright than blue light, with a lower color temperature than daytime sun, as the image above shows. Research has shown that red light doesn’t upset your sleep cycle like bright blue light. Red light therapy is showing great clinical results for people with insomnia and sleep disorders.

The light therapy is a simple, non-invasive treatment that delivers concentrated natural light to your skin and cells. Clinical research is showing that red light therapy can improve sleep quality and duration, and help people produce more of their own melatonin.

Light plays a major role in your sleep cycle. The body’s circadian clock interprets light as a sign of when to sleep and when to be awake. Artificial blue light from phones, computers, and other screens is extremely bright and can knock your circadian rhythm out of whack. Red light has the opposite effect: it’s ideal for evenings because it has a low color temperature—far lower than blue light and much closer to the natural sunset.

Red light therapy treatments are quick and simple: you just sit or stand in natural light for 5 to 15 minutes, ideally every day. This stimulates your mitochondria and gives your cells the natural light they need to make energy.

How Does Red Light Therapy Help You Sleep?

Natural light is a key ingredient for a healthy circadian rhythm and restful sleep. If you struggle to sleep, your light intake could be a big factor. Red light therapy delivers natural light like you’d get from the sun, but without UV rays, excess heat, or the need for sunny weather.

Red light therapy treatments supercharge your cells with the natural light they need to make more core ATP (adenosine triphosphate) energy. This helps your body run more efficiently, heal faster, and has shown great results for producing more natural melatonin and improving sleep disorders like insomnia.

Red light therapy treatments have shown great sleep results in a range of peer-reviewed clinical studies. One study on the sleep of pro basketball players showed that a 2-week course of red light therapy in the evening improved players’ sleep quality in the short term. Based on the results, the researchers suggested red light therapy would be a good non-invasive, drug-free solution to sleep struggles.

Overcoming Sleep Disorders with Red Light Therapy

Kaiyan's light therapy products are registered with the FDA as class II medical devices for the treatment of pain, strain, and inflammation. While the existing clinical research has been very positive for red light therapy and sleep, keep in mind that Kaiyan's devices are not cleared with the FDA for the treatment of various sleep disorders or melatonin.

Recent research on sleep disorders among people with migraine headaches has shown that red light therapy both decreased headache frequency, and was the only treatment that improved patients’ sleep disorders.

A 2014 study on cognitive function and traumatic brain injury (TBI) recorded that participants had significantly decreased episodes of post-traumatic stress disorder (PTSD), and improved sleep.

Analyzing patients’ electrical brain activity, a 2013 sleep study concluded that red light therapy was especially effective at helping people with sleep disorders fall asleep.


When I’m indoors training under the buzz of artificial lights, my body doesn’t get the natural light it needs. Add computers, cell phones, televisions, etc. and it’s easy to overload yourself with blue light. I used to have trouble sleeping after long training days, but since adding more natural light to my routine with red light therapy, I’ve been falling asleep as soon as I lie down, and I’ve been staying asleep all night.*

Red Light Therapy, Sleep, Depression, and Seasonal Affective Disorder (SAD)

Research is showing how closely mood and sleep disorders are interconnected. Parts of the brain that regulate sleep have also been found to closely affect mood. A 2013 review concluded that “nearly all people suffering from mood disorders have significant disruptions in circadian rhythms and the sleep/wake cycle.”

This Greatist post on natural light and serotonin gives good background on the connections between natural light intake, mental health, and sleep. It also mentions using Kaiyan's red light therapy devices to get more natural light, even when you can’t get more sunlight.

Trouble sleeping is one of the most common symptoms of seasonal affective disorder, a type of depression most common in the darker winter months. Some physicians treating patients with mental health disorders have said red light therapy both improves mood, and helps people with depression get better sleep.

Which is the Vitamin that is not Normally Found in any Vegetarian Food? — Vitamin D

What would happen if you don’t get enough sun?

Which is the vitamin that is not normally found in any vegetarian food? Vitamin D.

Scientists have defined vitamins as organic (carbon-containing) chemicals that must be obtained from dietary sources because they are not produced by our bodies. Vitamins play a crucial role in our body’s metabolism, but only tiny amounts are needed to fill that role.

The discovery of Vitamin D was the culmination of a long search for a way to cure rickets in the 1920s, a painful childhood bone disease. Within a decade, the fortification of foods with vitamin D was on the way, and rickets became rare in the United States. However, research results suggest that vitamin D may have a role in other aspects of human health.

Vitamin Dit’s absent from all-natural foods except for fish and egg yolks, and even when it’s obtained from foods, it must be transformed by the body before it can do any good. That’s why the energy of the Sun is so important.

The sun’s energy turns a chemical in your skin into vitamin D3, which is carried to your liver and then your kidneys to transform it into active vitamin D.

The main cause of vitamin D deficiency is a lack of direct sunlight.
The main cause of vitamin D deficiency is a lack of direct sunlight

Humans, day by day, spend less time outdoors. Most people work indoors now, and many of our leisure pursuits occur in an indoor setting as well. What’s more, when we are outside, many people avoid the sun as much as possible. The result is the body not absorbing enough UVB rays to create the amount of vitamin D it requires. Often, symptoms of vitamin D deficiency are quite mild. When noticed, they mainly consist of:

  • Bone pain.
  • Chronic fatigue.
  • Frequent bone fractures.
  • Muddled thought processes.
  • Muscle weakness.
  • Soft or deformed bones.

Though you may not notice any symptoms, that doesn’t mean that vitamin D deficiency doesn’t present serious health risks. These include:

  • Children may develop severe asthma.
  • Immune system problems, raising your risk of infection.
  • Insulin resistance, impacting your body’s ability to process sugar and increasing your risk of diabetes, multiple sclerosis, and glucose intolerance.
  • Osteoporosis, a condition that includes brittle bones that are more likely to fracture.
  • Reduced cognitive function.
  • Rickets, a bone disease that causes soft bones and skeletal deformities.
Other conditions that would happen without enough sunlight

Less chance of having a baby

Without sunlight, there will be more melatonin in a woman’s body. This is a hormone that suppresses fertility, thereby reducing her chances of conceiving a baby. Moreover, women who get less sunlight reach their menopause earlier than those who are exposed to the Sun. Men can also suffer from a lack of sunlight; it directly influences testosterone levels.

Less chance of having a baby

Raw nerves

It’s believed that if children don’t get enough sunlight, they’ll be more at risk of developing multiple sclerosis, a disease of the central nervous system when they become adults.

All those aches and pains

Without sunlight, be prepared to get more pains all over your body. Sunlight helps to warm the body’s muscles and reduce the pain caused by inflammatory conditions such as arthritis.

No sunny emotions

Image for post

Without sunlight, we would be forever stuck with the seasonal affective disorder (SAD), commonly known as the winter blues. It’s a form of depression that is specifically caused by a lack of sunlight. Artificial light cannot fully replace natural sunlight.

Recent evidence suggests that vitamin D may help prevent many disorders, such as diabetes, multiple sclerosis, rheumatoid arthritis, chronic obstructive pulmonary disease, asthma, bronchitis, premenstrual syndrome, increased blood pressure, strokes and heart attacks, and even cancer. Low serum vitamin D levels are also associated with being overweight, abdominal obesity, metabolic syndrome, stroke, and diabetes. In addition, having lower blood vitamin D levels for a long period is associated with increased heart attacks and all-cause mortality.

While I was initially skeptical at the 8-minute treatment, after I started to calm my mind, I fell in love with it. From age spots, to dry skin and acne, it cures whatever ails you. Could sound like a magic potion from a princess but is just light therapy. Before you go with the “What the…?” face, it’s only a matter of time before it shows up in most of the celebrities’ social media.

Most of our users describe it as

“warm and relaxing, and allows you to go into a meditative state of mind.”

LED light therapy has an established history of skin uses. The U.S. Navy SEALs began using it in the 1990s to help heal wounds quickly and to help regenerate damaged muscle tissues.

Since then, the treatment has been researched for different situations in aesthetics. It’s mainly noted for increasing collagen and tissues.

There are different frequencies, or wavelengths, used with LED light treatment. These include red and blue light frequencies, which don’t contain ultraviolet rays and are readily absorbed into the skin.

Different than Daylight

Unlike ultraviolet rays from the sun which damage the DNA of skin cells, “light emitted in this spectrum is perfectly safe,” said Dr. Susan Bard, a board-certified dermatologist based in New York City.

That means there’s no tanning or burning when you’re exposed to red light. Its effects happen deep inside at the cellular level. All living things need to make ATP cellular energy to function and survive, and nearly all living things rely on natural light to power this process in our cells every day. Red and near-infrared wavelengths of natural light stimulate the mitochondria in your cells, the powerhouses responsible for taking light, oxygen, and the food we eat — and turning it into usable energy for our bodies through the process of cellular respiration.

Uses of Red Light

Red light therapy has been used to treat or improve the following:

  • pain
  • inflammation
  • healing
  • tissue regeneration
  • autoimmune diseases
  • brain disorders
  • athletic performance
  • eyesight
  • heating
  • cancer therapy side effects

“The number of conditions red light can treat is ‘continuously expanding”

said Michael R. Hamblin, PhD, a principal investigator at the Wellman Center for Photomedicine at Massachusetts General Hospital and associate professor of dermatology at Harvard Medical School.

The Short Version

Light therapy delivers safe, concentrated wavelengths of natural light to your skin and cells, with no chemicals, UV rays, or excess heat. These red and near-infrared wavelengths of light stimulate the mitochondria in your cells similar to natural sunlight, reducing oxidative stress, and increasing circulation, so your body is able to make more core energy to power itself.
