Yawning is like a sleepy stretch for your brain. When you're bored or tired, it helps you wake up by sending more oxygen to your brain. Sometimes people yawn together, like when one person yawns and the whole class follows!
Examples
- When you're stuck in a boring class, you yawn because your brain feels sleepy.
- Your friend yawns, and suddenly the whole group is yawning like it's a chain reaction.
- After a long day at school, you feel tired and yawn as soon as you sit down.
