Sneezing is a natural reflex that helps protect our body from harmful particles. When dust, pollen, smoke, or even strong smells enter the nose, they irritate the nasal lining. In response, the brain sends signals to forcefully expel air through the nose and mouth, clearing out the irritants. It’s like the body’s quick cleaning system, and even sudden temperature changes or bright light can trigger it in some people.
Scientifically, sneezing involves several muscles working together—chest, throat, and face—all activated in seconds. Though it may seem simple, it’s actually a complex process controlled by the brain’s sneeze center. Sneezing also plays a role in spreading infections, which is why covering your mouth and nose is important. So next time you sneeze, remember—it’s your body’s way of saying, “Let me handle this!”
