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.
A night cap 🍺or a glass of wine 🍷 before bedtime may make you fall asleep. But does it affect overall #sleep ? This paper used a crossover design to test the effect of bedtime alcohol on sleep throughout the night. Alcohol reduced REM sleep.
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 yes, you see all of the changes that we just described, they sort of lose consciousness more quickly, they have fragmented sleep, and they have a significant reduction in REM sleep.
I would say that based on that data the principal protocol advice I would have for you is go to the pub in the morning that way by the time you're about to sleep the alcohol is out your system
even an afternoon single glass of wine if you measure sleep in the way that we measure it at my center with High Fidelity you can see compromises and impairments
alcohol will fragment your sleep so you wake up many more times throughout the night now typically they're so brief that you don't remember them but they have a measurable impact on your sleep physiology and as a consequence your own wellness biology
even though when you have a few drinks you're groggy and you think you're sleeping better you're just less conscious but you're actually sleeping worse
equally there are folks on the other side who can have you know a glass of wine with a late lunch and it still could crush their rem sleep
i think the take home here is that we should all go to the pub in the morning and that way the alcohol is out of our system by the evening but let let's not uh make that statement just stop drinking by noon and we think you're going to be fine
equally there are folks on the other side who can have you know a glass of wine with a late lunch and it still could crush their rem sleep
those those day those are so abundantly clear right like you you know that's that's as clear as how alcohol impairs sleep you know a late night meal is a is a great way to destroy a good sleep
at all doses when consumed an hour and a half or less from sleep alcohol reduces sleep onset latency and increases sleep disruptions in the second half of the night alcohol also increases slow wave sleep or deep in the first half of the night and at higher doses increases it during the whole night moderate and high doses about alcohol appear to reduce REM sleep particularly during the first half of the night
if you have ever consumed alcohol close to bedtime you're probably well aware of how alcohol impacts both the quality and quantity of your sleep
even if you consume alcohol in the afternoon it's still possible it could negatively affect your sleep
firstly it's beneficial to stop drinking alcohol at least 3 to 4 hours before bedtime this timing helps your body metabolize the alcohol before you enter the sleep period though it's important to note that alcohol's effects can linger and disrupt Sleep Quality even if consumption stops early in the afternoon
