What is jet lag?

Jet lag is a problem that afflicts many travelers around the world. There is a common misconception that jet lag is caused by flying, but its not. It simply happens more after flights because more people fly than anything else.
Simply, jet lag is your body's response to a different sleeping and waking schedule then it is used to. It is your body's way of freaking out in new situation and especially new places. People are all different and while one person may be severely affected, others adjust fairly quickly.

This also seems to depend on how much you travel and how easily your body adjusts to abrupt changes in its normal schedule. Frequent flyers often adjust and their body becomes used to the changes. For those who only fly once every blue moon, jet lag has the potential to be much worse.
Jet lag seems to happen most when traveling across more than one time zone in a flight. The whole reason this fatigue is called jet lag is because as people started traveling more with the advent of planes, it became associated with flying.
How do I avoid jet lag when I'm traveling?
While there is no way to actually cure jet lag short of remaining on your normal home sleeping schedule no matter what the time is in the new location. This is, however, virtually impossible for most people on long trips, but can work on short trips over weekends or for business.
You are better off simply trying to adjust before you go. If you know the time difference where you're going, perhaps a week or a few days before, try and get on a sleeping schedule as close to that in the place you're visiting as possible. This makes the transition much easier.
Depending on your work or time constraints, you can do it gradually, such as sleep and hour less or more per day a week before your trip or force yourself to be m ore extreme. The gradual method is the best solution because it allows your body to adjust naturally and slowly.
Thus by the time you actually get on the plane, your body is more normalized and synched with your destination. This is especially important to take into consideration during international travel to places that have remarkably different hours that those you are used to.
