Know When Airway Discomfort is Indicative of Something Serious
Discussion Coughing is a normal response that protects the airway. Typically, when an irritant enters the airway, the body responds by drawing in a quick breath and then closes the glottis as the air is forced out. This increases the pressure in the airways, which helps move the irritant out of the air passages. As the air is forced out past the closed glottis, the recognizable coughing sound is made. A cough that persists for several days or increases in its intensity and frequency can be a sign of a serious condition.
