What Causes ‘Jet Lag’ and How Can You Fix It Faster?

Jet lag happens when your body's clock gets confused. Imagine your body is like a little robot that knows what time it is. When you fly to a new place, the sun sets and rises at different times than it did before, so your robot gets mixed up. You might feel tired when it’s time to be awake or sleepy when you should be eating breakfast. To fix it faster, try going to bed at the new time zone's bedtime as soon as you arrive.
