The wavelength infrared puts out is longer than the wavelength of red light, which allows infrared to penetrate more deeply into the body. Thus, the reason infrared provides some similar, but some completely different benefits than red light. Red light is visible and is most effective for use on the surface of the skin. Red light occupies the “long end” of the visible spectrum with wavelengths of 630nm-700nm. Infrared light is invisible and is effective for use on the surface of the skin as well as penetration of about 1.5 inches into the body. Infrared sits right next to red light on the electromagnetic spectrum at 800nm to 1millimeter.
Although you don’t need a prescription to buy a light therapy box, it’s best to ask your doctor or mental health provider if light therapy is a good option for you. Ask whether you need to take any special precautions. Also discuss which type of light therapy box would best meet your needs, so you get the most benefit and minimize possible side effects.
@kimmy123 I do not think there will be any bad side effects. It’s just that it might confuse you if you do that. I think it’ll be better if you stick to one at first and when you think, see, feel that you achieve the result that you want then go ahead and try the other one. That is for me only, my opinion.
