Anyone who flies through time zones has to deal with that biorhythmic confusion known as jet lag. Body clocks don't adjust as easily as our wristwatches. But don't assume your first day will be worthless because of jet lag. Most people manage to enjoy a fun, productive first day. Jet lag can't be avoided, but here are a few tips to help minimize the symptoms.

Leave home well rested. Flying is stressful, especially if you fly half way around the world. If you leave frazzled, you may not be healthy for the first part of your trip. Plan as if you were leaving two days before you really are. Use that last 48 hours to mentally prepare for your adventure. You'll fly away well rested and capable of the enjoying every minute that is to come.

Drink plenty of liquids on the flight, eat lightly and rest. Long flights are dehydrating. Eat small meals and keep your caffeine intake to a minimum. Alcohol will stress your body and make jet lag worse. Sleep a couple of hours in flight if you can. It will help you be functional the day you land.

Reset your mind to local time. When the pilot announces the local time, reset your mind along with your watch. Don't make matters worse by reminding yourself what time it is back home.

On arrival, stay awake until an early local bedtime. If you nap in the afternoon you will most like wake up at midnight. Your body may beg for sleep but don't do it. Force your body to transition to the local time. Go out for a walk, get some fresh air and exercise.
