Explanation:

According to biology sneezing is just an involuntary reflex action. It, occurs when the nerve endings of the mucous membrane of the nose get irritated.
This irritation can occur due to the swelling of the mucous membrane of the nose. This happens when we get cold.
It can also be caused by the foreign bodies that somehow mange to get into the nose.
Again, even allergies produce irritation.
The act of sneezing is an attempt by the body to expel air to get rid of the irritating bodies.
Sometimes sneezing also occurs when our optic nerve is stimulated by a bright light.
During the act of sneezing, our whole body gets a jerk because the air comes out with a great speed – around 160 km per hour.
The whole body vibrates and the eyes get automatically closed. After the sneeze, the body becomes fresh and light.
