What is Sneezing?
Sneezing, also known as sternutation, is an involuntary reflex that expels air from the lungs through the mouth and nose, usually in response to irritation in the nasal passages.
This rapid expulsion of air helps to remove irritants and clear the nasal passages, providing relief as well as maintaining respiratory health.
Why Do We Sneeze?
The primary purpose of sneezing is to expel unwanted substances from your nasal cavity and maintain proper airflow.
The sneezing process begins when sensory nerves, specifically the trigeminal nerve, in the nasal mucosa are activated. The nasal mucosa is the moist lining within the nasal cavity, responsible for producing mucus that helps protect and moisturise the nasal passages.
These nerves send signals to the brain, which then triggers a coordinated response involving various muscles. The diaphragm, chest and throat muscles contract, while the soft palate and uvula move to direct air through the nose.
