cough

intro

A cough is a common and usually harmless reflex of the body's attempt to clear the airways of irritants, such as dust, smoke, or mucus. It can be caused by a variety of factors, including infections, allergies, or exposure to pollutants. In some cases, a persistent or severe cough may be a symptom of a more serious underlying condition, and medical attention should be sought if the cough lasts for an extended period or is accompanied by other concerning symptoms.
