Why do we yawn, and is it always a sign of being tired?

We yawn when we feel bored, tired, or even when we see someone else yawn, it's like a fun little signal between people!

What is a yawn?

A yawn is when your mouth opens wide, and you take in a big breath. It feels good, especially when you're sleepy or stuck in a long class at school.

Why do we yawn?

Imagine you’re sitting on the couch after playing for hours, your body is telling you it needs more air to stay awake. Yawning helps your brain get more oxygen and sends a message that it's time to rest or relax.

Sometimes, if you see someone else yawn, like your brother at breakfast, you might yawn too! It’s almost like a game, people copy each other, just like when you mimic how your teacher writes on the board.

Yawning isn’t always because you're tired; it can also happen when you're bored or even excited! So next time you yawn, remember, it's not just sleepy signals, but also a fun way people connect with each other.
