The Mechanics of Sneezing
A sneeze is a reflex action triggered by irritants in the nostrils, such as dust, pollen, or other allergens. This process involves tiny hairs called cilia that detect foreign particles and send a signal to the brain, prompting a sneeze to expel the irritants. The mechanics of a sneeze engage multiple muscle groups, causing a quick intake of air followed by an explosive release, which can launch respiratory droplets at speeds exceeding 40 miles per hour. This rapid expulsion underscores the importance of covering the mouth and nose during a sneeze to prevent the spread of germs.
