Full Answer

According to LiveScience, sneezing is a way in which the body protects the nasal passages from foreign particles. Air is forced out of the area of the lungs, and the brain orders the muscles to contract from the esophagus all the way to the sphincter. These orders include the muscles that control the eyelids. Certain sneezes can even cause the eyes to shed tears.
