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.

so this is why sometimes having a cold room but socks on or a cold room with a hot water bottle at the end of your bed just to warm the feet because it's the feet and the hands that need to get a little bit warm to bring the blood because they are the best radiators of heat out of your body
in terms of temperature it's a three part story for your extremities you need to warm up to cool down to fall asleep then you need to get cold to stay asleep and then you need to warm up to wake up so the reason that you may be finding latency easier here but quality of sleep there after worse is because it's counterintuitive how do i drop your core body temperature i'm going to tell you i'm going to warm you up but the reason is because if you take a hot bath or a shower all of the blood is charmed to the surface of your skin and it radiates the heat out of the core of your body so in fact your core body temperature plummets
so for folks who have trouble falling asleep at the start of the night we want to make sure their hands Fe and feet are warm enough right
so warming your extrem your extremities help you dump heat right so when you actually warm your hands and your feet you can actually help dump heat from your core because your vas are dilating and when you fall asleep you want to be dumping heat from your core hard to do that when you're vasoconstricted in your hands and your feet
So for folks who have trouble falling asleep at the start of the night, we want to make sure their hands or feet and feet are warm enough, right?
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.
