I am interested in the proper dosing of red light therapy. I don't think this issue has really been settled definitively, so I hope someone has some good answers/logic on what might be the best dose (dosing schedule) of red light.
If you don't understand why I'm I'm asking this question, well, here's why: Biphasic dose response in low level light therapy. (2009) http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2790317/
"A biphasic dose response has been frequently observed where low levels of light have a much better effect on stimulating and repairing tissues than higher levels of light. The so-called Arndt-Schulz curve is frequently used to describe this biphasic dose response. " ... "LLLT delivered at low doses tends to work better than the same wavelength delivered at high levels, which illustrates the basic concept of bipha-sic dose response or hormesis (Calabrese 2001b). In general, fluences of red or NIR as low as 3 or 5 J/cm2 will be beneficial in vivo, but a large dose like 50 or 100 J/cm2 will lose the beneficial effect and may even become detrimental."

"Very interesting. So basically, everything under 30 minutes is beneficial for you and once you do it too long it makes things worse?

Yes, at least there are no negative effects when limiting to 30min. At about 10 minutes my pulse begins to accelerate which means the good effects start to kick in. I might even go lower in the future with a maximum of 20mins. Peat also mentioned that shorter exposures with stronger light are better than longer ones with weak light. Dont know if that has something to do with the NO issue."
But I think that's far from definitive.
Anyone have any thoughts on dosing for red light?
