Sneezing Explained in Simple Words

Ever wondered why we sneeze? It starts when something irritates your nose. Tiny particles can enter your nose while you breathe. Your nose quickly detects them. Sensitive nerves inside your nose sense the irritation and send a warning signal. Signal reaches your brain. Your brain tells the body to react. Your brain sends the message back. Your breathing muscles prepare for a sneeze. You take a deeper breath as pressure builds inside your chest. Then, achoo! A sudden burst of air rushes out through your nose and mouth. Burst of air helps clear unwanted particles from your nose. Dust and pollen can trigger sneezing. Even cool air can sometimes set it off. Sneeze is a quick team effort between your nose, brain, and muscles. So, the next time you sneeze, remember, your body is protecting your nose.
