Jet Lag

Whether you’re flying for business or pleasure, jet lag can seriously impair your performance and holiday fun for days.

Jet lag occurs when the body’s rhythms are out of sync with your destination time the body operates on a 24-hour cycle, and travelling to another time zone alters the body’s natural rhythm causing jet lag. The more time zones you cross the worse it can be and travelling east generally has a greater affect on jet lag than travelling west. It is easier on the body’s biorhythms to say a few extra hours to the day, as in travelling west, than the reduction in the number of hours in a day when travelling east. The speed with which your body can realign itself to your new time zone, adjusting its body rhythm to daylight, darkness, eating and sleeping under the new time zone, affects the period of time you experience jet lag for.

The world is organized 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. This is why it is not difficult 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 end of your body isn’t ready for in your current time zone.

So what can you do to minimize the affects of jet lag? The following tips are intended to help you avoid the worst of jet lag and realign your body clock as soon as possible.
