once night time rolls around, you can easily suppress melatonin production & alter your circadian clock by viewing light that is too bright (any color, not just blue light). Thus, best to avoid bright lights ~10pm to 4am.
We can't find evidence that holds up here. Proponents are reasoning from mechanism or analogy rather than direct human data, and the most credible skeptics raise objections we can't dismiss.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
I don't want to mess up the circadian rhythms by being exposed to blue light at night so I like to have the blue lights off the red lights going to allow for normal production of melatonin through the through the bodies and doggedness mechanisms I don't want the suprachiasmatic nucleus which is connected with the eyes to be influenced by the blue light so the red lights are on anyway
