Sneezes are uncontrollable. Small particles, such as pollen or dust, float up to your nose, irritate your membrane, and set off a chain of events. When an irritant comes into touch with your nasal mucosa, it activates the trigeminal nerve, which sends a signal to the medulla, which is located in the lower portion of the brain.
As a result, your chest expands, your lungs fill with air, and you sneeze all over the place. You sneeze up to 5,000 droplets of mucus and air at rates of up to 100 miles per hour.
Your eyelids close as a result of that response, but why is one of science’s great mysteries. We believe it is an automatic reaction, similar to how your leg twitches when you are touched on the knee. What may be the source of the problem? You can close your eyelids to prevent germs from falling into your eyes when you sneeze. Perhaps your eyelids are closed as a result of a succession of muscles tightening as a result of the automatic response.

This reaction of your eyes hasbeen a kind of mystery for everyone. Everyone seems to have their own different theories, more complex than the other. But most fundamentally this can be explained by a simple term called reflex reaction, which means those reactions are generated, within a flash second by our bodies in coordination with our brain. Therefore it may be that our eyes stop the dust and mucus particles sneezed by our nose to enter into our eyes.
Basically sneezes can’t be stopped. Pollen or dust particles find their way up to your nose and start irritating your nasal membrane, and with this begins off a cascade of reactions. When an irritant from the environment comes into contact with your nasal mucosa, the trigeminal nerve is activated, and a signal is sent to the medulla, which is located in the lower part of the brain.
Your chest starts expanding and your lungs get filled up with air, and so you sneeze all over the place as a result. You can sneeze up to 5,000 mucus and air droplets every second at speeds of up to 100 miles per hour.
