In order to understand how Light Therapy affects the body on a biological level, you need to know about Nitric Oxide (NO).
In 1998 the Nobel Prize in Physiology or Medicine was awarded to Robert F. Furchgott, Louis J. Ignarro and Ferid Murad “for their discoveries concerning Nitric Oxide as a signalling molecule in the cardiovascular system.”
They discovered that the NO molecule influences every physiological activity of the body and that it is absolutely essential for improving circulation. As a vasodilator, NO opens up the vessels of the body including the capillaries, arteries, and veins.
Nitric oxide is produced throughout the body by the the lining of the circulatory system, the epithelium. When therapeutic light (Light Therapy) shines on living tissue, it triggers the epithelium to immediately release NO at that location.
Nitric oxide (NO) is responsible for:
- Vasodilation – increased circulation (vasodilation)
- Oxygenation – makes oxygen more available
- Pain relief – an analgesic effect
- Angiogenesis – re-growth of capillaries, blood transporters, lymph vessels, and nerves
- Phagocytosis – white blood cells ingest pathogens: bacteria, viruses, fungi, worms, and parasites
- Osteoblast production – supports bones, fractures, breaks, weaknesses, and cavities
- Collagen production – benefits aging skin by reducing wrinkles, improving skin tone
- ATP production – increase of the energy of cells for their work
When the cells release NO, you can see the benefits are almost infinite. Blood flow to an affected area can reduce inflammation. Healing can occur. Micro-organisms that don’t belong in the body have an unfriendly environment and cannot survive. Wounds heal faster, bones heal faster, and the cells replicate to do the work for which they were intended. New capillaries can even form for new growth of tissue.
Light Therapy allows the enhancement and escalates the release of NO from the epithelium and hemoglobin.
What NO does for the body is truly awesome, and to make NO more available all we need to do is shine therapeutic light on our body.
