Asthma and allergy coughs are typically caused by swelling or irritation of the airways. Allergies like hay fever can cause a chronic dry cough. If you're sensitive to dust, pet dander, pollen, mold, or other common allergens, then your allergy symptoms may include a cough.

How do you stop an allergy cough?

You can try inhaling steam, such as from a hot shower. The warmth helps open up your nasal passages while the moist steam keeps them from drying out. Saline nose sprays can help wash out the allergens and extra mucus, reducing your cough symptoms. These are available at a drugstore.

How do you know if your cough is from allergies?

If your cough comes on every time you are in certain places, or around certain things, and subsides quickly when you move away, it is most likely an allergy. And, if you have more severe coughing spells, which come and go, and are more serious when you are physically active, you may have asthma.
