That's why sneezes
If a dust particle gets trapped in the nose during breathing then it sneezes to remove that particle. If a large dust particle becomes trapped then the brain sends a message of excessive air filling in the lungs and during this time the eyelids flutter. Trigeminal vein is responsible for blinking. This vein controls the face, eyes, mouth, nose and jaw. On sneezing, the brain directs to remove all types of obstruction, which is also found in this nerve and for this reason the eyes shut.Eyes and noses are associated with cranial nerves. As soon as the sneezing, the lungs take out the air faster.
Why are eyes closed
At this time the brain gives signal to pull the nerves of the eyelids and the eyes shut. Trigeminal nerve is the part of the nervous system that controls the face, eyes, nose, mouth and jaw. During sneezing, it also sends the brain message to the barrier to the nerves. And in our response, our eyelids are flowing. The body prepares itself for it before sneezing.All the muscles of the chest become tight. You will be surprised to know when it sneezes, then its speed is 100 miles per hour. This habit of closing the eyes during sneezing after the creation of human beings gradually developed.
