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.
and i suspect that the aura ring and all wearables are using those inputs to determine sleep staging so a follow-up question to that is why do these metrics matter if your body temperature is increased you could see it overnight but say your body temperatures increase before you go to sleep or your respiratory rate is increased or your heart rate is up how can that impact sleep basically these things all suggest to me and i don't know if this is true but it just seems to me that all of these things are suggestive of more sympathetic tone
in as much as most people that are drinking alcohol are doing so in the evening and anybody who's used a sleep tracker you know you don't need to be Matt Walker to to very quickly do the experiment on yourself and compare a night of sleep with no alcohol a night of sleep with alcohol they're different
the less alcohol you have in your system when you sleep the better you're going to sleep
So some of you probably drink alcohol. And the less alcohol you have in your system when you sleep, the better you're going to sleep.
And so getting that feedback could sometimes be helpful.
