If you have kids, you probably already know how this tip works. Wear yourself out before flying so you can potentially get some sleep once you get to a different time zone. By exercising or doing some other physical activity before your flight, you may be tired enough on the flight to catch some Zzzs.
A flight from Atlanta to Paris can last more than eight hours. Flying from Atlanta to Hawaii can approach 10 hours and each covers many time zones. Sometimes you fly overnight and essentially lose a day. So the last thing you need to do is stay up when you finally do get a chance to go to bed. If you are able to maintain a sensible schedule, you won't suffer the full effects of jet lag as your body adjusts to the new time zone. Take a nap on the plane, too. Wearing yourself out will certainly help you get the sleep you need once you arrive at your destination.
