With so many people traveling everyday the term Jet Lag gets thrown around very loosely in modern travel. The majority of the time people can't tell you what it actually is, only what the effects could be. Part of preventing something involves actually knowing what it is. According to Wikipedia, Jet Lag is defined is a physiological condition which is a consequence of alterations to circadian rhythms; it is classified as one of the circadian rhythm sleep disorders. This results from rapid long-distance transmeridian (east-west or west-east) travel. In the medical community Jet Lag is known as medically referred to as "desynchronosis."
If we take an in-depth look at how our body operates on a daily basis we can get a better understanding of why Jet Lag actually affects us. The human body operates on what is called a "circadian rhythm," that are developed overtime as your body becomes accustomed to a regular pattern of wake and sleep cycles. If we take it a step further and look at what air travel can do to these rhythms it becomes clear as to why Jet Lag affects our body when we fly.
The world is divided into 24 time zones that each represent 1 hour of the day. These time zones are broken up by 15 degree intervals of latitude that correlate to 1 hour. So, the more you travel in either direction from your local time zone, the more your rhythms will be out sync. The body's circadian rhythm actually operates on a 25-hour cycle, which is why it is easy to stay up an hour late, but harder to go to bed an hour earlier. This results in a more severe effect when traveling west to east. Therefore your body's timekeeping center, the hypothalamus, will trigger activities that the rest of your body is not ready for in your current time zone.
So now you understand that it is the inability of your bodies natural rhythms to synch with the new timezone that creates the jet lagged effect. That is great to know, but you should now also learn how you can control, stop and potentially even avoid jet lag altogether. Rest assured, now when you read about a remedy or a technique to be used for jet lag, it will all make more sense now that you know what causes it.
Good luck out there.
Hopefully the next time you hear the word Jet Lag you will know what it is and how it affects your body. Remember, part of preventing is knowing first and then taking action.
