How do i avoid a jet lag?

DURING YOUR FLIGHT
As soon as you board, change your watch to the present time at your destination and try to eat and sleep by that time.
Drink lots of fluids to fight dehydration which can retard the process of resychronization.
Avoid alcohol, which is more potent at higher altitudes, as it accelerates dehydration and disrupts REM sleep.
Stretch and try to relax
DAY ONE OF YOUR TRIP
Follow the meal pattern and sleep/wake schedules .
Spend time outdoors in the sunlight as soon as possible.
Exercise, even a brisk walk will reduce your stiffness and pain due to the long flight and will create optimism and happiness.
Business executives and members of athletic teams should avoid doing business or engaging in sports until the second day abroad

sleep

sleep on the plane. simple

Get used,(adapt) to the new Timezone as fast as possible.

1. Don't travel too far.
2. Break your journey.
3. Take anti-jet lag tablets.
4. Sleep it off.
5. Get into the sun shine - it helps!

That's all I could think of. Happy travelling.

by anticipating the time on your arrival destination. so if you have to sleep in the plane, sleep, but sometimes, jet lag can't be avoided though.

sleep , drink lots of water and at time to time kep streacthing your toes this wuld make sure that they dont go numb , somepeople even walk to the rest room , on the pretext of making the circulation go on

Well... only can tell you what I did when I had my trip to Germany to visit my family. It took me 26 hours to get there and from the time I got up here in Sydney till I arrived in Frankfurt I was 30 hours awake (my fault, cant sleep in planes). Anyway... didn't go to sleep straight away, waited till it was sleeping time over there. I think that's the best thing to do, just try to fit into the time of your destination. Good luck.

Don't Fly - Walk

1. Start shifting your sleep-wake cycle to match that of your destination several days before departure, changing at the rate of one hour per day.

2. Begin adjusting to the time zone of your destination by resetting your watch at the beginning of your flight.

3. Sleep on the plane when it is nighttime at your destination. Earplugs, headphones and eye masks can help diminish noise and light.

4. Stay awake on the plane when it is daytime at your destination. Read a thriller with the light on and the window shade open, or cruise the aisles.

5. Drink plenty of water. The air on planes is extremely dry, and dehydration can worsen the effects of jet lag.

6. Avoid alcohol and caffeine while flying. They increase dehydration.

7. Exercise as much as you can on the flight during waking hours: stretch, walk down the aisles and do leg lifts (see "eHow to Exercise on a Plane," under Related eHows).

Many people find taking Melatonin helpful. (it is the hormone that tells your body to sleep.) Take it when it is night at the place you are visiting. When you get home, take it again at the "new" night time. It helps your body to adjust to the time changes.

Buy some 3 mg Melatonin tablets. It's an over-the-counter supplement that you will find in the vitamin section of the store.

If you are traveling east, on the day of your flight, take one dose of melatonin, as directed on the bottle, between 6 and 7 p.m. your time; you may have to take the melatonin on the plane. On the day you arrive and for the next four days, take one dose at bedtime (between 9 and 10 p.m.) local time of where you now are. If you will not be staying in this time zone for four days and will instead be traveling further east, take one dose of melatonin on the day before flying onward, again between 6 and 7 p.m. local time (but not at bedtime). On the day of arrival at your second destination, take one dose of melatonin at bedtime (local time) and for the next four days.

If you are traveling west, melatonin will not help much if you travel less than five time zones to the west. For longer distances west, on the day you arrive, take one dose of melatonin at local time bedtime and continue to do so for the next four days. If you wake up before 4 a.m., go ahead and take a little more melatonin (one or one-half dose) so you can get a complete night's sleep. If you're traveling further west in less than four days' time, take melatonin at bedtime the night before leaving. Then repeat the whole schedule again at your new spot.

Melatonin is a natural hormone that helps your body sleep. It is NOT a sleeping pill. Among other things, it helps the body reset its Circadian rhythm when traveling.

Well if you can afford it sit first class. Set lag is simply created from lack of clean oxygen. Also known as Carbon Dioxide. This is what gives you the tired "jet lag" feeling. Make sure you open the little fan vents and try to get as much fresh air as possible. Or like everyone else stated, sleep!
