Examples of Biological Effects Caused by Light NASA even use red light therapy to reduce the side effects of cancer treatments.
This finding led to further NASA-funded research and a spinoff company that focused on the benefits of red light in humans.
#Red light therapy skin
One incidental finding that the experimenters noted was that their cuts and other skin lesions healed noticeably more rapidly while they were exposed to the red LED lights for hours on end. Researchers involved in the NASA plant experiment had multiple small cuts and injuries that occurred while working with the plants. While the experiment successfully concluded that red light from an LED does encourage plant growth, it was an unexpected side effect that launched the use of red light in humans. The positive health benefits of red light were first discovered in 1993 during a NASA experiment using red light LED to encourage plant growth. Understanding how the newer form of therapy actually works, however, is very important for those who are considering using it. Red light therapy involves using specific wavelengths of light on different areas of the body and has been used to achieve many different health benefits, from enhancing sleep quality, to reducing chronic pain, to improving sport performance. While the initial discovery of red light therapy was related to the effect it has on speeding wound healing, many new discoveries have since emerged, allowing red light therapy to be used for a variety of different benefits. Red light therapy is a newer form of therapy that first came to be recognized by NASA researchers in the 1990s.
