what cause dry cough
A dry cough is known as ânonproductiveâ; whatâs called a wet cough is âproductiveâ (i.e. mucous-producing). The most common causes of a dry cough are asthma, allergies and acid refluxâin which other symptoms may or may not be present. Asthma Asthma, a condition in which the bronchial tubes become inflamed, usually causes wheezing, tightness in the chest and shortness of breath.
Low humidity, or moisture, in the air in your home can dry out mucous membranes, causing irritation in the throat and coughing. Investing in a humidifier to place in your bedroom at night can remedy this.
