Photobiomodulation, too much light

Dr. Michael Hamblin, PhD: "You started off introducing a concept you called infrared therapy. That is part of a thing that we call photobiomodulation. That starts about 750 nm and goes all the way into maybe 1200 nm. That's the near-infrared, which has a lot of biological effects and it also penetrates well into the body. Other colors of light (like blue and green) have a lot of biological effects but they don't penetrate too well. Ideally, we want to have highly active wavelengths of light that penetrate well into the body. […]

"The accepted mechanism in the mitochondria involves dissociation of nitric oxide from cytochrome C oxidase, increasing electron transport and ATP synthesis.

"The thing to remember about photobiomodulation is it's highly biphasic in dose. Many people will have gotten themselves into trouble by giving too much light.

Dr. Joseph Mercola: "I definitely want to touch on that, so please expand, because this is a massively important concept. It's the Goldilocks dose. There's this narrow range where it's going to give you benefit. Below that, not much benefit, and above you can actually cause harm."

Dr. Michael Hamblin, PhD: "Well, that's the idea, yes. It's not a narrow range, actually; it's quite a wide range. So you know obviously there's a power density, what we call mW/cm², there is a level where nothing will happen. You can sit in this light 24 hours a day, it will have no effect. But that's very low levels of light.

"Then you raise the dose and you get biological effects. If you keep raising it these effects will diminish.

"It's possible that if you give a huge amount of light you could actually damage the tissue. I think the thing about LEDs is that generally you put them right next to your skin and for a relatively brief period, 10 minutes, 20 minutes, that sort of period and you can feel the benefit.

"I don't know if you've seen, but this whole body light bed. James Carroll, THOR, makes this called the NovoTHOR, and it's an amazing thing. It's 500 watts of LED power. You can lie in it for like 10 minutes and you can feel the difference. I mean you really can."
