When you fly for a long time, especially across different time zones, something happens to your body. Your body clock gets confused because it thinks it's still in the old time zone. This makes you feel tired and sleepy even if you didn’t get enough sleep on the plane. It’s like when you stay up too late, you just can’t keep your eyes open.
Why does this happen?
Your body uses a special clock inside your brain, called the circadian rhythm, to know when it's time to be awake or asleep. When you fly far away, especially across oceans, this clock gets mixed up, and that’s why you feel so tired.
Examples
- You fall asleep on the plane but feel like you didn't get any rest because your body clock still thinks it's morning.
- After landing in a new city, you're wide awake at midnight but can’t stay up for more than an hour.
- Your friend sleeps through the whole flight, but you’re too tired to enjoy your vacation.
