Potential health benefits of red light therapy

Red light therapy (RLT) is a type of photomedicine, a wellness approach that uses light of different wavelengths to treat various health conditions. Red light exists at wavelengths between 620 nanometers (nm) and 750 nm, according to the National Center for Atmospheric Research. According to the American Society for Laser Medicine and Surgery, certain wavelengths of light cause changes in cells that affect how they function for the better.

Red light therapy is considered an adjunctive therapy, meaning it is intended to be used alongside conventional health care and MD-approved treatments. For example, if you have fine lines and wrinkles, you can use red light therapy with dermatologist-directed topicals, such as retinoids, or in-office treatments, such as injections or lasers. If you have a sports injury, your physical therapist may also treat you with red light therapy.

One of the problems with red light therapy is that research is not clear on exactly how and how much of this approach is needed, and how these protocols change depending on the health problem you want to address. In other words, there must be standardization everywhere, and such standards have not yet been established by the US Food and Drug Administration. However, according to some research and experts, red light therapy may be a promising adjunctive therapy for a number of health and skin care issues. Just remember, as always, to ask your doctor before starting any new treatment.

Here are some of the possible health benefits that red light therapy can bring to your overall health care routine.
