Light therapy, also known as phototherapy, is a form of treatment that uses certain types of light to help improve various conditions or health issues. Light therapy works by exposing the body to specific wavelengths of light, which can stimulate natural physiological responses in the body. It can be used to treat a variety of conditions, including seasonal affective disorder (SAD), skin conditions like psoriasis and acne, and sleep disorders. In general, light therapy is considered safe, non-invasive, and has few side effects.

NASA has conducted research on the benefits of light therapy and has found it to be effective in treating a variety of health conditions. In particular, NASA's research has focused on the use of light therapy to help regulate sleep patterns and alleviate the symptoms of seasonal affective disorder (SAD). Their research has shown that exposure to certain wavelengths of light can stimulate natural physiological responses in the body and help to improve these conditions. As a result, NASA has developed and patented a range of light therapy devices and technologies that are used both in space and on Earth.
