We sneeze when we inhale a lot of dust laden air-when dust particles enter our nostril, it triggers a message to the brain. The brain instructs the nasal chamber to initiate sneezing. This is a method to remove the unwanted dust particles from the nostril. sneezing is a type of defense mechanism used by our body.
