I don't know, as a neuroscientist this is very confusing. Blue light generally is linked to arousal, as in this study for instance: https://pubmed.ncbi.nlm.nih.gov/32973462/
I wonder if there is some paradoxical effect if you put in a lot of blue light you get a decrease in arousal? Perhaps it could also be something like repetition suppression, where there is a lot of activity and arousal initially, but this causes a backlash and you get a relaxing effect?

Or maybe it's all just placebo.
