Sneezing is like your body’s way of hitting the “eject” button. When something irritating like dust or pollen gets in your nose, your body goes, “Nope, get outta here!” Your brain sends a signal to clear it out, and your chest muscles, diaphragm, and throat team up to create a big burst of air. It’s like a super-powered nose explosion! We often sneeze multiple times because sometimes one blast isn’t enough to kick out all the irritants. It’s like your nose saying, “Alright, let’s make sure we got everything!” So, sneezing is your body’s dramatic way of keeping your airways clean, launching irritants out with a powerful, sometimes repeated, “Achoo!”
