What Causes Seasonal Cough, and How Is It Treated?

Seasonal cough is primarily caused by pulmonary infection, bronchitis, or allergic cough, among other factors. Specific management depends on the underlying cause, as outlined below:
1. Pulmonary infection or bronchitis: Seasonal changes and abrupt fluctuations in temperature—physical and chemical stimuli—can independently trigger coughing or coexist with respiratory tract infections, thereby exacerbating pre-existing respiratory symptoms such as cough and sputum production. When an active infection is already present, exposure to sudden temperature changes may further aggravate the cough associated with the acute infection. Treatment is recommended with anti-infective agents, such as cefradine, cefalexin, or cefaclor.
2. Allergic cough: This typically occurs upon exposure to allergens—for example, pollen or bacterial invasion—which act as triggers for coughing. In such cases, comprehensive warmth preservation and supportive care are advised. Patients should increase fluid intake and may be treated with oral medications including azithromycin and montelukast sodium.
      During cough episodes, ensure fresh indoor air; smoking must be strictly prohibited, and rooms should be ventilated regularly by opening windows. Avoid irritant foods—including those excessively sweet, salty, greasy, fried, cold, or spicy—and refrain from beverages such as coffee.
