Seasonal cough is most common in spring, or autumn. In spring, when flowers bloom, the cough is irritated by pollen, or the smell of flowers, or willow; in autumn, due to sand and dust in the air, or artemisia, etc., which can be irritating to the lungs, causing a hoarse, dry throat and cough without sputum. This cough is seasonal and is considered to be a high airway reaction or allergy-induced cough. Patients are advised to seek medical attention in a timely manner and seek anti-inflammatory and cough suppressant treatment under the guidance of a doctor, and usually wear a mask to avoid contact with allergens.
