What causes to sneeze?
sneezing is a reflex. When irritants — such as germs, dust, pollen, animal dander, or pollutants, just to name just a few — infiltrate the nose lining, the brain sends out a signal to get rid of it. That triggers a deep breath, which gets held in the lungs.
A sneeze begins with a tickling sensation in the nerve endings that sends a message to your brain that it needs to rid itself of something irritating the lining of your nose. You first take a deep breath and hold it, which tightens your chest muscles.
The pressure of air in your lungs increases, you close your eyes, your tongue presses against the roof of your mouth and suddenly your breath comes out fast through your nose.
