I thought some people here might be interested. For those of you experimenting with NIR light, for more than just eyes, this might be of interest:
"Interestingly, the researchers conducted the same experiment with a smaller cohort several months later but delivered the exposure in the early afternoon. No improvement at all was detected, suggesting circadian cycles play a significant role in the mitochondrial response to deep red light."
So, try your experiments at different times of day.
