Scientific Background of Phototherapeutic LED devices

Concerned for astronauts who might be injured or become ill in long term space flight, NASA studies determined that Earth’s gravity is necessary for normal human cell growth, noting that “wounds heal less effectively in space than here on earth”.
In response to this significant health risk, NASA developed LED (light emitting diodes) technology that shows great promise for delivering light deep into tissues of the body to promote wound healing and human tissue growth. “NASA’s LED device stimulates the basic energy processes in the mitochondria (energy compartments) of each cell, particularly when near-infrared light is used to activate color sensitive chemicals (chromophores, cytochrome systems) inside the cell”.
In addition, NASA reported that DNA synthesis in fibroblasts and muscle cells quadrupled when exposed to LED light. Based on these findings, NASA observed that this type of improved wound healing may have multiple applications which benefit civilian medical care, military situations and long term space flight.
During the first decade of this century, numerous companies have commercially introduced products claiming to be based on NASA’s LED technology and capable of delivering efficacious therapeutic benefits for conditions ranging from “Alzheimer’s to Zits”.
Benefits of Infrared Light Therapy
Circulation is increased by increasing the formation of new capillaries, which are additional blood vessels that replace damaged ones. New capillaries speed up the healing process by carrying more oxygen as well as more nutrients needed for healing and they can also carry more waste products away. The iIncreased circulation heasl and repairs damaged skin tissue. This increase in circulation also causes the body to rid itself of wastes and toxins.
Stimulates the production of collagen which lessens build up of scar tissue
Collagen is the most common protein found in the body. Collagen is the essential protein used to repair damaged tissue and to replace old tissue. It is the substance that holds cells together and has a high degree of elasticity. By increasing collagen production less scar tissue is formed at the damaged site. Infrared Light Therapy was engineered and designed by scientists at LED Technologies, based on the NASA specifications from a NASA laboratory study on wounds healing.
Increases lymphatic system activity
Edema, which is the swelling or natural splinting process of the body, has two basic components. The first is a liquid part, which can be evacuated by the blood system, and the second is comprised of the proteins, which have to be evacuated by the lymphatic system. Research has shown that the lymph vessel diameter and the flow of the lymph system can be doubled with the use of light therapy. The venous diameter and the arterial diameters can also be increased. This means that both parts of edema, liquid and protein, can be evacuated at a much faster rate to relieve swelling.
Increases RNA and DNA synthesis
This helps damaged cells to be replaced more promptly. RNA, Ribonucleic Acid, a polymeric constituent of all living cells and many viruses, consisting of a long, usually single-stranded chain of alternating phosphate and ribose units with the bases adenine, guanine, cytosine, and uracil bonded to the ribose.DNA, Deoxyribonucleic Acid, is a nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA.
