Friday, February 27, 2009

Jet lag is a temporary disorder that causes fatigue, insomnia and other symptoms as a result of air travel across time zones. Dr. Edward Hill discusses jet lag in todayís 60 Second Housecall.

Your body has an internal clock that controls your temperature, blood pressure and hormones. When you travel across several time zones in one day, your internal clock can get out of sync. This is called jet lag.

Jet lag is usually worse when you travel in an eastward direction. The symptoms might be worse in older people.

Jet lag, also called desynchronosis, has many symptoms which can include sleep problems, you may have trouble concentrating and you might feel weak or clumsy.

Jet lag can cause headache and upset stomach. Some people with jet lag don't want to eat. Jet lag usually is worse for the first two days after you arrive, then it gets better.

To reduce your chances of getting jet lag, be sure to get enough rest before you start traveling. Drink lots of nonalcoholic drinks like water during the flight so you donít get dehydrated.
