One of the worst aspects traveling internationally is suffering from jet lag. It can cause you to sleep poorly, wake up much earlier than you would like and have trouble adjusting to a new eating schedule. There are some ways that you can prepare for jet lag in advance, as well as ways to get over it faster when you travel. The following are the best tips to fighting jet lag.Adjust Before You FlyIn the days leading up your flight, start waking up earlier each day if you plan to travel East. If your flight goes West, try staying up later than normal for a few days, and waking up later as well. Just an hour or two can make a significant difference when the time comes to change the clocks on your travels. Consider wearing a watch set to your destination's time to start following their schedule for meals as well, just to get you on track for when you arrive.On Your FlightIf you generally do not drink, a long flight is not the time to start, as you will feel the effects more at altitude. Keep hydrated with lots of water, and get up at regular intervals to keep moving if you want to stay awake. If you want to sleep, bring along an eye mask or even earplugs to block out the lights and sounds.When You ArriveTry to eat a light meal when you arrive to wake you up, and then immediately try to get on the current time schedule. If you have trouble staying awake in the day, go outside to spend some time in the sun.
