Jet lag

What is it?

Jet lag is the feeling of tiredness and fatigue that may come with traveling across time zones.

Causes:

When traveling across time zones, your body's internal clock gets "out of synch." The pineal gland (in the brain) makes melatonin (a hormone) in response to changes in the daylight. This cyclic production of melatonin can regulate several important functions in the body. If you cross time zones, the body's internal clock can easily and slowly reset itself. With airplane travel, several time zones can be quickly crossed, going faster than the speed with which the body's internal clock can reset itself. This may be a bigger problem when time is lost traveling from West to East.

Signs and Symptoms:

There may be many symptoms with jet lag. These include fatigue, daytime drowsiness, headaches, nausea (upset stomach), and not being able to sleep. You may also not be able to do normal activities.
