Why Do People Yawn When They’re Bored or Tired?

Yawning is like a big stretch for your brain. When you’re bored or tired, your body wants to wake up or cool down, and yawning helps with that. It’s also why people around you might start yawning too!

Why Yawning Is Contagious Sometimes it feels like someone is giving you the yawn from across the room. This happens because seeing others yawn activates special [brain cells](/search?q=brain%20cells) called [mirror neurons](/search?q=mirror%20neurons), which help us understand and copy what others are doing.
