Cough is an important reflex action, which the body undertakes to get rid of substances that are irritating the air passages. A cough is usually initiated to clear a buildup of phlegm in the trachea, by forceful expulsion of air at high speed away from the body. You can choose to cough (a voluntary process), or our body may cough on its own (an involuntary process).



Cough can be of 2 types - acute and chronic. An acute cough is one that begins suddenly and is present for less than 3 weeks. They can be infectious (common cold, sinus, pneumonia), or non-infectious (asthma, bronchitis). Chronic coughs are present for more than 3 weeks. .
