How Allergies Cause Coughing
Allergies occur when your immune system overreacts to harmless substances like pollen, pet dander, or dust mites. When you're exposed to these allergens, your body releases histamines and other chemicals as part of an inflammatory response. This reaction can cause a range of symptoms, including sneezing, congestion, and irritation in the airways — leading to a dry, persistent cough.
Here’s what else you need to know:
- In addition to direct irritation of the throat and airways, allergies can also cause postnasal drip. This happens when excess mucus from your sinuses drips down the back of your throat, triggering a cough reflex. Postnasal drip is one of the most common causes of an allergy-related cough.
- For some people, allergies can trigger asthma-like symptoms, including coughing, wheezing, and shortness of breath. This is known as allergic asthma and occurs when allergens cause inflammation and constriction in the airways, making breathing difficult.
- Hay fever, or allergic rhinitis, is another common cause of coughing. Allergens like pollen can cause the nose to become congested or irritated, and this nasal congestion can lead to a persistent cough, especially at night when lying down.
Common Triggers of Allergic Coughs
Several common allergens can lead to a cough, especially during certain seasons or in specific environments. These triggers include:
- Pollen: Especially common in spring and fall, pollen from trees, grasses, and weeds can cause severe allergy symptoms, including coughing.
- Dust Mites: These microscopic organisms thrive in bedding and upholstered furniture, leading to indoor allergy symptoms year-round.
- Mold Spores: Mold grows in damp areas, such as bathrooms and basements, and can be a trigger for allergies.
- Pet Dander: Proteins found in an animal’s skin flakes, saliva, or urine can cause an allergic reaction in sensitive individuals.
- Environmental Irritants: Smoke, pollution, or strong fragrances can exacerbate allergy symptoms and lead to coughing.
Symptoms That Differentiate an Allergy-Induced Cough
An allergy-related cough is usually dry, meaning it doesn’t produce mucus like a cough associated with a cold or respiratory infection. This type of cough is often accompanied by other allergy symptoms such as:
- Itchy, watery eyes
- Sneezing
- Nasal congestion or runny nose
- Postnasal drip
- Scratchy throat
Unlike a cough caused by a virus, which may resolve within a week or two, an allergy cough can last for weeks or even months, depending on your exposure to allergens.
How to Manage and Treat an Allergy-Induced Cough
If you suspect that allergies are behind your chronic cough, there are several ways to manage your symptoms:
- Over-the-counter antihistamines, decongestants, and nasal sprays can help reduce inflammation and alleviate symptoms. Medications like cetirizine, loratadine, or fluticasone can effectively control coughing caused by allergies.
- Identifying and avoiding your allergy triggers is key to managing symptoms. For example, try keeping windows closed during high pollen seasons and using air conditioning instead of outdoor fans.
- Rinsing your nasal passages with a saline solution can help clear out allergens and reduce postnasal drip, which may reduce coughing.
- For individuals with severe or chronic allergies, immunotherapy may be an option. This involves receiving regular allergy shots over time to reduce your sensitivity to specific allergens.
