Sneezing is a reflex
The reason that we sneeze is because our bodies are reacting to irritants—including dust, pollen, and animal dander—in the nose lining. When these irritants get into our noses, our brain receives a signal to get rid of them and we sneeze. You take a deep breath and hold it, causing the muscles in the chest to tighten. That pressure forces your tongue against the top of your mouth and the air to travel quickly out of your nose when you release your breath.
Sneezing is our body rebooting
Researchers from the University of Pennsylvania reported on why we sneeze in the Journal of the Federation of American Societies for Experimental Biology. They concluded that we need to reset our nasal cavity every so often… and we do that by sneezing. Don’t miss these strange facts about the human body you never knew.
