The Ultimate Guide to Jet Lag

Flying on an airplane over numerous time zones can create jet lag, which can affect a traveler's body for several days. Whenever you travel to a new time zone, your internal clock is going to need some time to adjust.

The main cause of jet lag is rapidly crossing time zones. Generally, flying east is worse than flying west because you must wake up earlier than you are accustomed to. People that are traveling north to south or vice versa, do not seem to have the problems because they are not crossing time zones.
