Yawning is like a group hug for your brain. When someone yawns, it makes you feel like you should yawn too, almost as if your brain is saying, 'I'm tired, and so are you!' Scientists think this might help people relax or stay in sync with each other. It's like when your friend starts laughing, and suddenly you can't stop either!
Examples
- When your mom yawns during breakfast, you suddenly feel sleepy too.
- You're watching a movie alone, but when the main character yawns, you can't help it, you start yawning too.
