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.
our circadian disruption our circadian rhythms are destroyed because of artificial light and we just don't go in the sunlight anymore which so sleep and sunlight I think are very interconnected but the average American now is spending 93% of their time indoors
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.
people spend 90% of their time indoors now their daytime environments are too dim their nighttime environments are too bright
So that means even though we wake up, we don't get that very bright light that we are designed to get in the morning. So our body gets confused completely when it's day or when it's night. Although we kind of can work our way through, our body is not completely compliant or completely is figuring out when it's day or night. So that's why all the circadian rhythm, all these rhythms and gene expression in different organs are completely desynchronized.
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.
