Coughs may cause discomfort at this time of year, but remember coughing is normally a protective action that helps clear irritants or blockages from your airways. When you cough, an explosive rush of air is pushed out of your lungs,
Coughing is most often caused by short-term irritation of your upper airways, normally due to inhaling foreign particles or mucus dripping from the back of your nose. Colds and flu can create inflammation of your respiratory passages and cause coughing.
