Why Do We Sneeze When We Are Ill?

We sneeze when we are ill because our body is trying to clean out something it doesn’t like.

Imagine your nose is like a tiny vacuum cleaner. When you're sick, germs or dust get into your nose and start causing trouble. Your nose notices this and says, “Hey, I need to kick these bad guys out!” So it sends a big burst of air, that’s your sneeze! It's like when you blow your nose really hard to get rid of a smelly sock.

Your body has special sensors in your nose. These sensors tell your brain, “Something is wrong here!” Your brain then tells your muscles to tighten up and send air flying out of your nose, blam! That’s your sneeze.

Sometimes you even close your eyes or your mouth when you sneeze. It's like a secret team working together to help you feel better faster!

Sneezing is just one way your body helps you get healthy again.
