What is red light therapy? Red light therapy (RLT) is a controversial therapeutic technique that uses red low-level wavelengths of light to treat skin issues, such as wrinkles, scars, and persistent wounds, among other conditions. 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 growth and photosynthesis of plant cells. Red light were 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. What is Near Infrared Light Therapy? Near infrared light therapy is essentially the same as red light therapy, except infrared energy is invisible, and it penetrates the body deeper than red, reaching deep into soft tissues, muscles, joints, and bone. Near infrared light therapy is where light therapy gets serious. The combination of red light therapy with near infrared energy is being researched for amazing things such as the reversal of traumatic brain injury, stopping and healing the debilitating effects of stroke and heart attack, and the regeneration of damaged nerves and severed spinal cords. While all of that is unfortunately still years away from common practice, the power of near infrared light therapy has already been FDA approved and is available in-home for the relief of chronic pain. As with red light therapy, near infrared light therapy does not mask the symptoms of pain, it encourages the healing of the actual cause of the pain and so, in many cases, after a course of treatment with infrared light, the pain is gone for good.
