Why do we yawn, and what is its physiological purpose?

We yawn when we're tired or bored, and it helps our body wake up or relax, like giving your brain a little stretch.

Yawning is when you open your mouth wide and take in a big breath. It feels good because it makes you feel more awake or more relaxed, depending on the time of day.

When we yawn, our brain gets more oxygen, like giving it a fresh drink of air. This helps it work better if we're tired, or calm us down if we're bored. It's kind of like when you take a big breath before running, it gives your body more energy.

Sometimes, seeing someone yawn makes you yawn too! That’s because our brain notices the yawn and wants to copy it, just like how kids imitate their friends or parents. It's a way of connecting with others, even if you don’t realize it!
