I'm no biology person either, but in terms of photons, I do find these interesting;

'Biological tissues typically produce an observed radiant emittance in the visible and ultraviolet frequencies ranging from 10−17 to 10−23 W/cm2 (approx 1-1000 photons/cm2/second).[1] This low level of light has a much weaker intensity than the visible light produced by bioluminescence, but biophotons are detectable above the background of thermal radiation that is emitted by tissues at their normal temperature.

While detection of biophotons has been reported by several groups,[2][3][4] hypotheses that such biophotons indicate the state of biological tissues and facilitate a form of cellular communication are still under investigation,[5][6] and claims that biophotons are responsible for physical healing are unsupported. Alexander Gurwitsch, who discovered the existence of biophotons, was awarded the Stalin Prize in 1941 for his mitogenic radiation work.[7]'
