Cough is a way of your body to clean your airways. When you cough up phlegm, it removes smoke particles, dust and mucus from your trachea, throat or lungs. Sometimes you don't cough up anything. Then you have a dry cough or a tickling cough. For a dry cough is often not prescribed a cause.

If the mucous membrane on the inside of your respiratory tract is stimulated, it makes extra mucus. Then you need to cough. You get incentives from smoke, dust and chemicals such as chlorine and ammonia. If you have an inflammation of your respiratory tract, for example, because you have a cold, then you also get irritations. Because of the many coughing you also often get a dry chapped throat. That chapped throat gives irritations, so you have to cough again..

Occasionally coughing is really not bad. Often coughing is usually harmless and usually passes by itself within 2-3 weeks. You can easily swallow coughed up phlegm. This does not go back to the respiratory tract but leaves the body with the feces.
