Fit Bits: Sleep on It


If you skimp on sleep while on a ski vacation, you can increase your chances of having an accident, according to Dr. Bob Ballard, director of the Sleep Disorder Center at the National Jewish Medical and Research Center in Denver, Colo. "Ski injuries occur when skiers are fatigued," he explains. "Muscles don't work as quickly, and the body can't react as fast."

So, when traveling across different time zones, try setting your circadian clock a few days before your trip to ease the adjustment period. While on the plane, do your best to stay awake. At your destination, avoid heavy meals and alcohol late in the evening, along with over-the-counter sleep aids. Finally, read a book and drink a glass of warm milk or chamomile tea before bed¿even if you've been out partying.
