14 Reasons You're Always Tired
You have a glass of wine (or two) before bed
A nightcap sounds like a good way to unwind before falling asleep, but it can easily backfire. Alcohol initially depresses the central nervous system, producing a sedative effect, says Allen Towfigh, MD, medical director of New York Neurology & Sleep Medicine, P.C., in New York City. "But it ultimately sabotages sleep maintenance." Alcohol creates a rebound effect as it's metabolized, which creates an abrupt surge in the adrenaline system, he says. This is why you're more likely to wake up in the middle of the night after you've been drinking. Dr. Towfigh recommends stopping all alcohol three to four hours before bedtime.
