sneezing

Sneezing is a reflex action that occurs when the body’s sensory nerves detect irritation in the lining of the nose or throat. This triggers a signal to the brain, which then coordinates rapid, involuntary contractions of the chest muscles, diaphragm, and muscles in the face. These actions expel air forcefully through the nose and mouth, helping to remove irritants like dust, pollen, or germs. Essentially, sneezing is the body’s way of clearing the respiratory passageways to protect and maintain respiratory health.
