Sneeze

A sneeze, or sternutation, is a semi-autonomous, convulsive expulsion of air from the lungs through the nose and mouth, usually caused by foreign particles irritating the nasal mucosa. A sneeze expels air forcibly from the mouth and nose in an explosive, spasmodic involuntary action resulting chiefly from irritation of the nasal mucous membrane. Sneezing is possibly linked to sudden exposure to bright light, sudden change (fall) in temperature, breeze of cold air, a particularly full stomach, or viral infection, and can lead to the spread of disease.

Why We Say Bless You after One Sneezes

"Some people believed that a sneeze causes the soul to escape the body through the nose. Saying "bless you" would stop the devil from claiming the person's freed soul. Others believed the opposite: that evil spirits use the sneeze as an opportunity to enter a person's body. There was also the misconception that the heart momentarily stops during a sneeze (it doesn't), and that saying "bless you" was a way of welcoming the person back to life." people.howstuffworks.com
