Why Do We Yawn When We’re Tired or Bored?

Yawning is like a sleepy signal that our brain sends out when we're tired or bored. When we see someone else yawn, it’s like they’re saying, 'Hey, I'm really tired, maybe you are too!' Our brains copy the action, and suddenly everyone in the room starts yawning like it's a group activity. It helps us all feel more relaxed and ready to fall asleep or take a break.
