Sleep / Myth or fact?

Is a drink good for sleep?

Introductory · 2 min read · ■■■□ moderate evidence

Mostly false. A drink may make it easier to fall asleep; that part is true. But it does not do the night as a whole any good. The second half of the night is more broken, and the body recovers less.

We explain how alcohol affects snoring and pauses in breathing during sleep in Alcohol, late meals and snoring. Here we look at small amounts, that is, at "one drink".

What we know

• The shared finding of studies in healthy volunteers: at every dose, alcohol speeds up falling asleep and breaks up sleep in the second half of the night¹.
• The first onset of dreaming sleep (REM) is delayed at every dose¹.
• In real-life heart rhythm recordings from thousands of employees, even a small amount of alcohol weakened the body's recovery in the first hours of sleep².
• The body gets used to alcohol's sleep-inducing effect over time; someone who drinks regularly may need more for the same effect³.

What we do not know

• The effect of small amounts on sleep over many years is not well known; most studies cover a single night or a short period.
• Whether everyone is affected in the same way is unclear. In one study the effect was stronger in younger people, and physical activity did not protect against it².

Saying "there is no evidence" here would be wrong: there is evidence, and it goes against alcohol. The feeling that "a drink helps me rest" may come from the brief relaxation as you fall asleep. What happens during the rest of the night usually goes unnoticed.
