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.
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.
when you split it apart there was um a 35% decrease in cancer mortality specifically and there was almost a 60% drisking of cardiovascular mortality risk if you are regular versus irregular
what they found was that those people who are in the top quarti of being most regular relative to those people who are highly irregular if you had good regular sleep you had a 49% reduced risk of mortality relative to someone who was very irregular of that General allca mortality risk
I knew that regularity was important I don't think we understood how important and the strength of mortality drisking if you're regular or increased risk if you're irregular that this metric of R carried in the qqr T equation
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.
