A cough lasting more than 10 days is often due to a lingering infection, throat irritation, or allergies that have not fully settled. Try drinking warm fluids like water or soups to soothe the throat, and use steam inhalation to help clear irritation and ease breathing. Avoid cold drinks, dust, and smoke as these can trigger more coughing, and keep yourself well hydrated through the day to reduce dryness. Getting proper rest and keeping your surroundings clean can also support recovery. If you develop fever, breathlessness, chest pain, or thick mucus, it may need attention. Consult a doctor if the cough is not settling or begins to worsen.
