Near-infrared light at 839 nm may increase mitochondrial function and ATP production.

“In particular, they can access the so-called organelles, which I described at the beginning of the episode. In particular, they can access the mitochondria, which are responsible for producing ATP. Now, the simple way to think about this for sake of this discussion is that as cells age, and in particular, in very metabolically active cells, they accumulate what are called ROSs, reactive oxygen species. And as reactive oxygen species go up, ATP energy production in those cells tends to go down. It's a general statement, but it's a general statement that in most cases is true. There are some minor exceptions that don't concern us that have to do with cell types different than the ones that I'm talking about now. So the way to think about this is that red light passes into the deeper layers of the skin, activates mitochondria, which increases ATP, and directly or indirectly reduces these reactive oxygen species.”

“it releases nitric oxide from cytochrome c oxidase and that basically allows your body to make more ATP which amps up the light egg cells”

“photo oxidizes cytochrome oxidase and by doing that the enzyme has more affinity that's a conformation of the enzyme that has more affinity to oxygen for oxygen consumption”

“what I can tell you it's we found another way to try to intervene with mitochondrial respiration using light in particular infrared light that can go through the tissues and the photons in the near-infrared light are absorbed by cytochrome oxidase”
