It's four in the morning and you're stuck in your hotel room, bored out of your skull but wide awake. Thanks jet lag! That's the price you pay for changing so many time zones in a single airplane ride. Here's why it happens, and how you can prevent it from ruining your trip.
✔ What Is Jet Lag?
Jet lag is, simply, a breakdown in your circadian rhythm caused by rapid travel through multiple time zones. Say, for example, you were to fly from San Francisco to New York City. Your body doesn't have time to adjust to the three-time-zone difference over the course of the flight, so your body "thinks" that it's three hours earlier than what your watch says. And until your internal clocks can reset themselves to the local time, you're left groggy and tired.
