Yes, allergies can cause chronic cough in children by triggering inflammation and irritation in the respiratory tract. Common allergens such as pollen, dust mites, pet dander, and mold can lead to allergic rhinitis or hay fever, which often results in a persistent cough. Postnasal drip, where mucus drips down the back of the throat, can further aggravate the cough.

Managing allergies through avoidance of known allergens, using air purifiers, and maintaining a clean environment can help reduce symptoms. Medications such as antihistamines, nasal sprays, and allergy shots may also be effective in controlling allergic reactions and alleviating chronic cough. Early identification and management of allergies are key to preventing chronic respiratory issues in children.
