Recurring allergic cough is usually triggered by dust, pollution, weather changes, or other allergens and may lead to bronchitis if airway inflammation worsens. Treatment includes avoiding triggers, using antihistamines or inhalers as prescribed, and consulting a doctor to check for asthma or chronic allergy.

Morning tight cough with occasional runny nose is often due to allergic rhinitis or post-nasal drip, especially from dust, weather changes, or bedroom allergens. Avoid triggers, keep your room dust-free, and consult a doctor if symptoms persist or worsen.

In a 30-year-old, asthma can be allergic (triggered by dust or pollen), non-allergic, exercise-induced, occupational (work-related), or adult-onset asthma. A doctor can identify the type based on symptoms and lung function tests to guide proper treatment.
