The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

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.

Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
after dark Yes you heard me earlier all of the lights in my house are red I'm not just any red not LED red because that's going to have flicker it's incandescent red now that may have Flickr as well but I believe it's less and I like the incandescent red bulbs you can find them on Amazon so every light bulb in my house after dark is incandescent red so if you come to my house for dinner and it's 6 30 which sometimes I eat at 6 30 yes we're eating dinner in red lights or candles I really enjoyed using candles and low light at night beeswax candles not something like paraffin I don't like the smell of those
Erling Holland needs some red lights in his house. Zero flicker film grade red lights. They can be LED if they're zero flicker film grade or incandescent.
10 minutes of bright outdoor light within the first hour of waking anchors the circadian phase and improves sleep onset that night.
Morning sunlight exposure shifts the cortisol awakening response forward, improving daytime alertness.
Long-term morning sunlight reduces age-related macular degeneration risk.
Sleep regularity predicts all-cause mortality more strongly than sleep duration.
Tracking deep sleep on a wearable accurately reflects EEG-measured slow-wave sleep.
Caffeine has a half-life long enough that consumption after 2pm measurably degrades deep sleep in slow metabolizers.
