"A glass of wine before bed will help you sleep better."
"Wine can be both the best and worst sleep hypnotic," says Allison T. Siebern, PhD, CBSM, clinical assistant professor and the associate director of the Insomnia & Behavioral Sleep Medicine Program at Stanford University School of Medicine. It's true that a glass of pinot noir will lower your stress levels and put you in a more relaxed mood, which can put you in the right frame of mind to sleep. But if you have that glass right before bed, it will probably break down in your system approximately three or four hours later, causing you to sleep fitfully or wake up, says Siebern. Instead of a nightcap, she recommends having your drinks with dinner, or at least three to four hours before bedtime.
