Red Light, Blue Light, Green Light Therapy…so many choices!

Amber Light, Red Light Therapy, Blue Light Therapy, and even Green Light Therapy…what in the heck is with all of these different light therapy wavelengths? There is so much information online, the internet is flooded with misinformation. There are all of these different wavelengths of light claiming to treat different things that it can feel overwhelming. Trust me, I know! With all of the marketing hype, it can be difficult to wade through it all so let me share some information related to various wavelengths you may be seeing on the market. First, let me just say that more is not always better with wavelengths. If a device is offering 6 different wavelengths, but only 3 of those wavelengths have been scientifically proven to be effective, the rest of the power output is essentially being wasted on those other wavelengths of light. So just because a device advertises tons of wavelengths, don’t be fooled. Pay attention to what wavelengths are being offered and what your goals are with the device. For example, if you are focused on skin related issues, buying a device with a blue wavelength would be preferable to an infrared wavelength.

Blue light has shorter waves, with wavelengths between about 450 and 495 nanometers (nm). Red light has longer waves, with wavelengths around 620 to 750nm. Infrared light sits right next to red light on the electromagnetic spectrum at 800nm to 1000nm. Then there is green light therapy with a wavelength that ranges from approximately 520 to 570 nanometers.

Blue light has a higher frequency and carries more energy than red light. Light with longer wavelengths can reach deeper parts of the body. Red light therapy penetrates the skin to stimulate collagen and reduce inflammation. Blue light helps treat skin conditions like acne, penetrating the pores and destroying bacteria whereas infrared light is effective for use on the surface of the skin as well as penetration of about 1.5 inches into the body.

And in between all of the above, there is green, yellow, etc. But the reason we don’t hear as much about them is because the science doesn’t support their effectiveness in the same way as the other wavelengths. However, more research is continues on the various wavelengths and already green light and particularly green light therapy has shown to benefit migraine suffers!

Was that too much? I’m trying to slowly unpeel the onion on how light therapy works because it’s not a one size fits all. It really depends upon what your goals are.
