If you have ever experienced jet lag(飞行时差反应),you know how much of a drag it can be. Jet lag happens as a result of air travel, when traveling between two or more time zones. Your body is used to operating in a certain time zone, and when its timing is affected, you’re likely to have problems.

Edward Norton’s character in the movies Fight Club faces the struggle of jet-lag-induced sleeplessness due to his constant traveling. Sleeplessness is just one of the effects of jet lag, and it can lead to other problems, such as tiredness, memory loss and confusion. That’s not something you should have to fight on a business trip and it certainly won’t make your vacation very enjoyable, either.

Sleeplessness is the biggest problem for travelers that suffer from jet lag. Don’t worry. You can do something to prevent it.

Modify(改变)Your Body Clock

To prevent the effects on your body’s timing that come with crossing time zones, you need to change your body clock sooner, rather than later. You can do this by putting yourself on the same time as your destination time zone before you fly. If you know that you will be traveling to London from the eastern United States, you’ll have a five-hour time difference to deal with. Plan for it.

Avoid Heavy Food and Alcohol(酒精)

Part of the pleasure of flying commercially, especially if you fly business or first class, is taking advantages of the food and drinks. If you want to avoid jet lag, though, you should think twice. Eating heavy food will only make the jet lag worse. It isn’t good to drink alcohol during a flight, either, because it may make you drowsy. Wait until your body adjusts(调整) before you decide to have heavy food or drink alcohol.
