Cough and sneezing after getting wet in the rain are usually due to a mild viral infection or sudden exposure to cold. The body may react with throat irritation and nasal symptoms for a few days. Take adequate rest, drink warm fluids and consider steam inhalation to ease congestion and soothe the throat. Avoid cold foods, dust, and further exposure to the cold to prevent worsening. Consult a doctor if symptoms persist, worsen or are associated with fever.

A cough with allergy and chest discomfort can be due to airway irritation or a mild infection. Try warm fluids and steam inhalation, and keep your surroundings free of dust and animal allergens to reduce triggers. Rest well and avoid cold air, smoke, and anything that worsens your symptoms. If the chest discomfort worsens, breathing becomes difficult, or symptoms last more than a few days, consult a doctor for proper evaluation.
