Why do we sneeze?
People sneeze in response to an irritation or tickle in their nose. When the inside of your nose gets a tickle, the nerve endings send a message to the sneeze center in your brain. This transmits a call to an amazingly complex set of muscles to get rid of the tickle quickly.
In a split second, your stomach, chest, diaphragm (the breathing muscle beneath your lungs), vocal cord, throat, face and eyelid muscles flex and … Ah-Choo! At a roaring 600 miles per hour, your body tries to dislodge the pollen, dust, pepper, mold, virus or bacteria trapped in your nose. (Kids sneeze at about 100 miles per hour.)
Some people sneeze when they breathe cold air. Others sneeze in threes. And still others sneeze when stepping from dark into bright light. If this happens to you, then you have a condition called “photic” (meaning “light”) sneezing.
