You may have heard the term “productive cough” or “wet cough.” A cough is productive (or wet) when you’re able to bring up mucus.
The speed of the air travelling through the airways and the thickness of the mucus determine how effective your coughing is.
You’ve probably heard of an unproductive cough, too. This is more commonly known as a “dry cough.” This is when you’re unable to bring up any mucus. In some cases, an unproductive cough is a result of irritated airways that haven’t produced excess mucus.
