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.
is it the way that we were designed to sleep bif phasically versus the Siesta like and I don't think it is there is no good collection of evidence if you look at the biology of our human rhythms that argues that there is this magical period of a huge spike in Arcadian Rhythm that happens right in the middle of the night that should force us awake
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.
is that the way our physiology and our circadian rhythms are designed no it doesn't seem to be there's usually one study that's cited that suggests maybe we should do that but overall the physiology that we know of for human beings doesn't seem to suggest that that was that was more sociologically driven rather than biologically driven
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.
