Many physiological processes depend on the light cycle. There are special photoreceptive molecules in our cells called cytochrome c oxidases, which are enzymes of mitochondria's respiratory chain. Mitochondria are cellular organelles that supply cellular energy. Cytochrome c oxidases absorb light in the phototherapeutic window (NIR and R spectrum), triggering a sequence of redox reactions on the inner mitochondrial membrane. These primary mechanisms' photobiological response is evident in the photo signal transduction to secondary mechanisms that ensure several clinical effects: wound healing, improved blood and lymph circulation, regeneration, and immunomodulation. Photobiomodulation provides the organism with substantial support in maintaining homeostasis of the body. This applies particularly to the red and the near-infrared spectrum. Light contributes to maintaining or re-establishing balance in the organism at even cellular level, where it:
- Acts as an antioxidant contributing to the protection of cells from free radicals.
- It affects the proteins that protect cells from degenerative processes.
- Enhances the osmotic resistance of red blood cells, thus preventing hemolysis.
- Affects the growth factors in the nervous system and microvessels and the muscular and connective tissue.
- Affects cell signaling.
- Regulates inflammations, the immune response, and circadian rhythms.
- Supports tissue regeneration.
- Stimulates local circulation.
- Supports the lymphatic system.
Light affects the mechanisms of disease incidence and substantially shortens the recovery time. It thus helps reduce medical costs, as it cuts down on the use of medicinal products. A light stimulator cannot replace a healthy lifestyle and medical care required in injuries or illnesses, but complementary effects have been proven. The irradiated area shows better circulation, cellular metabolism, and energy production in cells improves, and the healing and regenerative effects on the tissue are stimulated. The light stimulator can be used as an independent or complementary therapy.
Therapeutic light devices can be modulated at various frequencies. Modulation unites the properties of light with technically compatible frequencies that additionally stimulate the body’s regenerative abilities and enhance the effects of light therapy.
Seven different frequencies are used to treat different injuries and alleviate illnesses through light. These frequencies, Nogier frequencies, regulate various conditions. Dr. Paul Nogier was a French neurologist and the founder of auriculotherapy, who determined frequencies for treating individual types of tissue. The seven experimentally determined Nogier frequencies can be used in light therapy to support an affected organ's rehabilitation through acupressure points or of injured tissue. Furthermore, these frequencies help establish a healthy balance of energies through meridian and acupressure points according to acupressure and acupuncture principles. Voll frequencies can also modulate light devices. These frequencies are used for bioresonance therapy with individual electronic devices that include both frequencies for diagnosing and frequencies for treating conditions that occur due to impaired cellular activity. The 2.45 Hz Voll frequency is effective for acute, subacute, and chronic conditions. Using the light of a wavelength of 610–670 nm and 830–870 nm helps with muscular and skeletal injuries, pain, tendon and ligament injuries, and injuries to the nervous system. It affects the acupuncture points. It strengthens and relaxes the body and directly affects individual systems of the organism or individual organs. It is used for edema, sinusitis, insomnia, and vegetative disorders. Light therapy is often complemented by Nogier and Voll frequencies that simulate various tissue types and offer effective support to treating various medical conditions and injuries. The type of injury or the medical condition determines the appropriate frequency to be used.
Seven Nogier frequencies to achieving a healthy energy balance of the body that are most commonly used in light therapy:
- Frequency A: 292 Hz
- Frequency B: 584 Hz
- Frequency C: 1,168 Hz
- Frequency D: 2,336 Hz
- Frequency E: 4,672Hz
- Frequency F: 73 Hz
- Frequency G: 146 Hz
It generally applies that lower frequencies are used to facilitate cell activity and for regeneration, while higher frequencies (C-E) are used for alleviation and relief of pain. The effects of these frequencies are enhanced if several frequencies are included in one therapy.
- Analgesic effect: G, E.
- Regenerative effect: A, B, F.
- Relaxation: C, D, G.
Benefits & Effects
F : Facilitates cellular activity, especially when this activity is reduced. Activates bodily functions. Stimulates acupuncture points
G : Anti-inflammatory function stimulates the immune system. Accelerates recovery. This setting is often combined with other settings, as inflammations comprise several phases.
A : It has a stimulating effect on the tissue of ectodermal origin (the central and the peripheral nervous system, the sensory epithelia, the epidermis with hair, nails, cutaneous glands, the pituitary gland, the epiphysis). It facilitates recovery following surgical procedures, restores the skin and the mucous membrane (wounds, wrinkles, ulcers, aphthae, herpes). Helps with migraines. This frequency is used as the universal frequency for acupuncture points.
B : It has a stimulating effect on endodermal origin tissue (the liver, gall bladder, pancreas, intestinal loop, the urinary bladder). It enhances blood and lymph circulation. It also affects the conduction of nerve fibers. It prevents the development of blisters in the initial phase of herpes and facilitates wound healing in the mouth cavity.
C : It stimulates mesodermal origin tissue (connective and supportive tissue, striated and smooth muscle tissue, hematopoietic organs, the lymph, kidneys, the genitals). It supports bone healing and facilitates recovery following muscle, ligament, and joint injuries. It relaxes the muscles and improves joint mobility.
D : Complements frequencies A and C.
E : Relieves pain.
Modern light devices for photobiomodulation are frequency modulated and are intended for specific therapies that we wish to conduct. This means that in addition to treatment with the seven basic frequencies, they enable the use of preset programs that automatically combine various frequencies in recommended time intervals. The frequencies change automatically concerning the type of injury or the medical condition. After the therapy, the devices shut down automatically.
