My erstwhile psychiatrist was completely obsessed with blue light. That, and caffeine, she told me to cut them out. She insisted that staring at a screen late at night, and just prior to sleeping, was my undoing.

And to a certain extent, she was right, but it was not "the blue light" per se that was damaging my psyche. Rather, it was the stuff within the light that was getting me agitated and angry. It was the disputes on Wikipedia, the social media arguments, the ragebait I found everywhere, the F.U.D. leading to my paranoia and rebellion and loss of trust.

It's like people who say "5G is harmful to our brains" -- well, yes, because whatever is being transmitted over that 5G is harmful, like porn or social media -- not the mere frequencies themselves!
