How to deal with jag-lag？
Flying across one or more time zones can cause jetlag，making it difficult to stay awake during the dayand fall asleep at night.While a person usually recovers from jet lag after 3 or 4 days，it is often necessary to recover faster.
Eating and sleeping pattern Steps：
Step 1 Set a time：Determine what time you want to wake up and eat breakfast in the new time zone.
Step 2 Fast：Avoid eating anything for the 12 to 16 hours before you want to wake up.
Step 3 Eat：Eat a healthy and nutritional meal with high caloric value after your 16 hour fast.This overrides your normal sleep cycle and resets it.
Step 4 Be consistent：Keep a consistent eating and sleeping pattern until you need to switch it again.
如何调整时差？
飞越一个或多个时区会造成时差反应，白天难以保持清醒，夜间难以入睡。通常一个人可以在三到四天的时间里克服时差反应，然而，现实情况却需要你更快地恢复。
进食和睡眠模式步骤：
1.设定时间：确定自己在新的时区想要什么时间醒来，什么时间吃早餐。
2.禁食：在你想要醒来的时间12到16个小时之内不要吃任何东西。
3.饮食：16个小时的禁食之后吃一些健康有营养的东西。这样可以推翻正常的睡眠规律，重新设定。
4.坚持：保持一致的饮食和睡眠习惯，直到你需要重新调整。
