Jet Lag Disorder

Jet lag, also called jet lag disorder, is a temporary sleep problem that can affect anyone who quickly travels across several time zones.

Your body has its own internal clock, called circadian rhythms. They signal to your body when to stay awake and when to sleep.

Jet lag occurs because your body’s internal clock is synced to your original time zone. It hasn’t changed to the time zone of where you’ve traveled. The more time zones crossed, the more likely you are to experience jet lag.

Jet lag can cause daytime fatigue, an unwell feeling, trouble staying alert and stomach problems. Although symptoms are temporary, they can affect your comfort while on vacation or during a business trip. But you can take steps to help prevent or lessen the effects of jet lag.
