Last Call: Study Links Late-Night Drinking to Bad Sleeping


A new study shows that boozing before bed may mean a bad night's sleep, and once you do fall asleep, late-night drinkers are more apt to snore.

Researchers at the London Sleep Centre found that despite many people using alcohol to sleep, liquor actually prevents you from sleeping deeply by reducing rapid eye movement—better known as REM sleep—which is considered to be necessary to getting a good night's sleep. Without adequate REM sleep, you become drowsy and irritable during the day.

And researchers found that the more you drink, the worse it gets.

“Alcohol may seem to be helping you to sleep, as it helps induce sleep, but overall, it is more disruptive to sleep, particularly in the second half of the night,” said researcher Irshaad Ebrahim. “Alcohol also suppresses breathing and can precipitate sleep apnea."

The study used data from 27 separate experiments.
