UV light affects the body in visible ways, stimulating the production of melanin and providing a “tan” after being in sunlight or artificial UV lighting. The best known examples of light affecting the body are related to ultraviolet (UV) light. However, there are well-proven medical examples of specific wavelengths of light causing physiological effects and a scientifically-supported explanation of how red light therapy works.Įxamples of specific wavelengths of light having a significant affect on the body have been around for centuries. The idea of simply shining light on an area of your body and having that cause a beneficial effect could sound a bit farfetched.
People who are learning about red light therapy sometimes think that it sounds too good to be true. While red light therapy research has come a long way in the three short decades it has been researched, there are still new potential applications for red light therapy that continue to emerge. Red light therapy is used for pain management, to stimulate hair growth, improve post workout recovery, and many other purposes. Today, red light therapy research has developed significantly, and there are many other applications that it is used for beyond just wound healing support. This discovery sparked an interest in how red wavelengths of light actually worked to cause this affect and what other potential applications there were for red light-based therapies. Red light therapy is a newer form of therapy that only began getting recognition around 1990, when the National Aeronautics and Space Administration (NASA) researchers discovered that red wavelengths of light shortened healing times for wounds.
