17 Reasons For Prolonged Cough

4. Air Pollution

Air pollution has been an ever increasing concern for some time now. A lot of us have no choice but to breathe in polluted air, especially those living in developing cities. We are constantly exposed to a number of pollutants, germs and impurities, making us vulnerable to illnesses, particularly respiratory conditions. Poor air quality can lead to a lingering cough. You can minimize these effects by taking precautions such as avoiding spending unnecessary time outdoors, and keeping out of the sun if you live in a high-ozone area.
