You’ve probably heard someone say, “I sleep better when I’ve had a drink or two to relax me.” While that may be true in small doses, larger ones can actually have the opposite effect.
According to ScienceDaily, large amounts of alcohol are known to shorten sleep latency, increase slow-wave sleep, and suppress rapid eye movement (REM) during the first half of sleep. During the second half, REM increases and sleep becomes shallower.
Alcohol interferes with the restorative functions of sleep. Which means you could feel sluggish and tired the next day.
So, while a drink may help you relax, it might actually create a new set of problems with sleeping. And that’s something you definitely want to avoid.
