A cough is the body’s way of responding to inflammation and irritation anywhere in the airways from the throat, larynx, bronchial tubes or lungs. Depending on where the aggravation is will depend on how the cough sounds. It is commonly believed that there are 2 types of cough; chesty (productive – bringing up phlegm and mucous) and dry (non-productive). A dry cough occurs when the throat and upper airways become inflamed, whereas a chesty cough comes from deeper within the lungs and chest.
Chesty coughs are a regular feature for most during the colder months of the year, often being coupled with a cold or the flu. Most will see their coughs up and leave within a couple of weeks, but some are a little more persistent and may linger depending on what their root cause is
