Why can not open eyes sneezing?

Sneezing is to protect our nostrils from invading foreign molecules, by creating a force of air from the lungs with a speed of 160 km / h. But this reflex also involves many other movements.

When stimulated, the brain's sneezing center controls contractile muscles, from the esophagus to the sphincter. It includes eye control muscles. Many people sneeze and shed some tears.

No one understands why. It may be because the body has developed to bind the nostril protection to the eyes, or it may be the result of the connection between every part of the body.

Scientists also cannot explain why some people sneeze early in the morning, or this reflex is pleasant in this person but uncomfortable in others.

In any case, sneezing is dominant in that it is the only reflex that makes you get a "salty rice" blessing from a stranger.
