Why do we always close our eyes when we sneeze?

Why do we always close our eyes when we sneeze?

Sneezes are very powerful because not just the nose is involved. It is a reflex response that involves the muscles of the face, throat, and chest. You have to close your eyes when you sneeze because the muscles that close your eyes are part of the reflex response as well.

One more last tidbit of information about sneezing. Thomas Edison came up with the idea of movies from watching someone sneeze in 1888? He was looking at still sequential pictures of someone sneezing, and realized that if you viewed them quickly in a sequence, that you might be able to make a movie.
