well after reading the article many times now my understanding is that they harmonize or synchronize all cels in the body (because these just represent the dna base for all the dna "branches"), I think because they are infrared frequencies they act a bit like a pleasant sunshine calming and at the same time energizing the whole body with "sun rays"
I'm not sure where you live but for me this is a very welcome aspect as I live in the part of the world where sun is not so powerful anymore pls does not shine every day, especially during the winter time
but as they say "nothing in an excess can be healthy" so I guess there's a limit to it as to anything else that feels good and one has to keep this in mind...
