>>253503 A sneeze is a semi-autonomous, convulsive expulsion of air from the nose and mouth. An unimpeded sneeze sends two to five thousand bacteria-filled droplets into the air. The medical name for sneezing is sternutation.
Sneezing is generally caused by irritation in the passages of the nose. Allergens such as pollens, pet dander, house dust mites, as well as nonallergenic particles are usually harmless, but when they irritate the nose the body responds by expelling them from the nasal passages. The nose mistakes strong odors, sudden chills, bright lights (see photic sneeze reflex), and even orgasms in some people for nasal irritants, and it tries to defend itself with a sneeze.
It is almost impossible for one to keep one's eyelids open during a sneeze, although some rare individuals report having little if any trouble doing so. The reflex of shutting the eyes serves no obvious purpose: the nerves serving the eyes and the nose are closely related, and stimuli to the one often trigger some response in the other.
