People yawn in groups because they copy each other. When one person yawns, it's like a signal that says, 'I’m tired!' and others feel the need to join in. It’s kind of like when you see someone laugh, and suddenly everyone starts laughing too! Scientists think this happens because we’re connected through our brains, something called empathy helps us understand how other people are feeling, and yawns might be a way we share that connection.
Examples
- A class full of students starts yawning after the teacher yawns during a boring lecture.
- Your best friend yawns right before lunch, and soon everyone at the table joins in.
- You see your mom yawn on the bus, and you feel an urge to yawn too.
