Why We Close Eyes When Sneezing

Sneezing is involuntary. Small particles like pollen or dust float to your nose and irritate your membrane, triggering a series of reactions. Or more technically, when an irritant is in contact with your nasal mucosa, it triggers the trigeminal nerve, which sends a signal that ends up in the lower part of the brain called the medulla. Your chest expands in response, your lungs fill with air and you sneeze everywhere. In fact, you sneeze around 5,000 droplets of mucus and air at speeds up to 160 km / h (100 mph).

Your eyes close as part of this reaction, but this is one of the great mysteries of science as to why. We think it's an involuntary response, a reflex, like when your leg is shaking after being hit on the knee. What could be the cause? You can close your eyes so that your sneezing does not fall on your eyes. Or maybe your eyes are closing because they are part of a series of muscles that contract during this involuntary response.

The nose and eyes are connected by the cranial nerves, so the stimulation of sneezing rises from one nerve to the brain, then from another nerve to the eyelids, triggering a blink for most people.
