Introduction. A cough is a reflex action to clear your airways of mucus and irritants such as dust or smoke. It's rarely a sign of anything serious.

Most coughs clear up within three weeks and don't require any treatment. For more persistent coughs, it's a good idea to see your GP so they can investigate the cause.
