An unfortunate side effect of travel, jet lag can easily suck the fun out of the first few days in a new time zone. Whether you're planning on traveling to a new city for business or pleasure, these three tips will help expedite your acclimation.

1. Ease your body into the time zone of the city you'll be visiting.
Take a week or so before your departure to incrementally shift your sleep schedule so that upon arriving in your destination, your circadian rhythm is already in sync. Go to bed earlier for an eastward trip, later for a westward trip. If you'll be traversing multiple time zones, you may want to consider breaking up your travel into smaller flights.

2. Get outdoors.
Staying inside only worsens jet lag. Being exposed to sunlight will help stimulate a correction of your biological clock. Try taking a short walk to clear your head.

3. Stay hydrated.
Once you're in the air, drink eight ounces of water per hour. This will help curtail the dehydrating effects of cabin air. You may be tempted to reach for a cocktail, but be forewarned that alcohol worses jet lag. Avoid caffeine, as well, as it acts as a stimulant and may prevent restful sleep.
