Getting Your Zzz’s

Pillow time gives you energy, bolsters your immune system, boosts your memory, and even helps you get (or stay) slim. Cut slumber short, and you’ll increase your risk for anxiety and depression. “Lack of sleep has also been associated with hypertension, glucose intolerance, and belly fat—all risk factors for heart disease,” says judge Nieca Goldberg, MD.

Aim for seven to eight hours of sleep a night, the amount that studies show is ideal. If you’re up-and-at-’em on less, don’t sweat it: Some people are just wired that way, Dr. Goldberg says. But if you have trouble falling or staying asleep, or can’t seem to drag yourself out of bed on a regular basis, talk to your doctor about possible underlying causes, such as anxiety or sleep apnea.
