What is the benefit of sneezing?
Sneezing protects us by clearing our nasal and bronchial passages and our lungs of dust, pollens, and other irritating substances. Sensors in our noses and sinuses detect the irritants and send a signal to the tiny hairlike cilia that line our nasal passages to expel them.
What happens if you stop yourself from sneezing?
