The Body’s Way to Clean House
Sneezing is your body’s quick way of clearing out unwanted stuff from your nose. Tiny things like dust, pollen, germs, or even a tickle can irritate the inside of your nose. When that happens, your brain sends a message to your body: blow it out! And just like that, a big burst of air shoots out through your nose and mouth to get rid of the irritants.
A Powerful Reflex at Work
Sneezing is a reflex, which means it happens automatically. You can’t stop a sneeze once it starts. It’s a team effort, too; your chest muscles, throat, and even your eyes all react at the same time. That’s why you usually close your eyes when you sneeze. It might sound loud or feel sudden, but sneezing is a clever and safe way your body protects your lungs from tiny invaders.
