Let’s look at these surprising reasons, so that if you have ruled out cold or flu as the culprit, there are still some ideas that you can pursue as to what is causing your dry cough.

1. Allergies
One of the causes of dry cough that may surprise you is allergies. Many people get allergy – or “hayfever” reactions in the United States. There are a number of causes for allergies, including pet dander and pollen. The problem is, when most people experience these symptoms, they are restricted to things like itchy and watery eyes and sneezing. A dry cough only happens in a small percentage of cases where the cause can be traced to allergies. It depends upon how your body reacts to the allergens, as well as what the allergen actually is. For example, some forms of mold will cause your lungs to react as well as trigger other allergy symptoms. If you normally suffer from allergies, then consider this is a potential cause. You may be able to take an antihistamine in order to combat these allergy symptoms to a certain extent.
