Do you ever wonder why people cough? People cough when they are choking on food or drink or when they are sick because they are trying to clear what ever is in the body or in their trachea out. Phlegm, excess mucus down the airway can cause coughing, and irritation in the lungs and trachea can cause severe coughing bouts. Respiratory illnesses like Bronchitis and Pneumonia are especially bad for causing coughing (as is the highly dangerous contagious disease known as SARS), both of which are mainly caused by bacterial or viral infections.
