jetlag

Transcontinental traveler's grogginess

Jetlag is the fatigue and disorientation that follows rapid travel across time zones.

Your body's internal clock remains synced to your departure point while local time demands otherwise.

Symptoms include insomnia, daytime drowsiness, difficulty concentrating, and digestive upset.

It took me three days to get over the jetlag from Tokyo.

Also spelled jet lag.
