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.

There are only two voluntary muscle groups that are speared from the paralysis, bizarre. One, your extra ocular muscles, because if they were paralyzed, you wouldn't be able to have rapid eye movements. And the other that we later discovered was the inner ear muscle.
those signals actually are blocked in the brain stem prevented from from reaching your muscles because the nerves that don't go through your brain stem like the ones that control your eye movements aren't subject to that blockade that's why you can produce the rapid eye movements in in RM sleep
it's only your voluntary sceletal muscles meaning that your involuntary muscles things for example such as your respiration that helps you breathe in your heart that's the reason that we you know survive and live another day after sleep
when you dream your brain paralyzes all of your voluntary muscles so that you can dream and dream safely and you don't act out your dreams with the exception that at least two muscle groups your extraocular muscles that move your eyes and your inner ear muscles for some reason they are spurred from the paralysis

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.
