Runny nose and sneezing commonly occur due to a viral cold, Allergic Rhinitis, dust exposure, weather changes, pollution, or sensitivity to strong smells. Symptoms may also include nasal blockage, watery eyes, throat irritation, mild headache, cough, or body discomfort, depending on the cause. Anti-allergy or cold-relief medicines may help reduce sneezing, a runny nose, nasal irritation, and watery eyes temporarily. If symptoms are allergy-related, avoiding dust, smoke, perfumes, pet exposure, and sudden temperature changes may help reduce repeated attacks. Steam inhalation, warm fluids, sufficient hydration, saltwater gargles and proper rest may also gradually improve comfort and nasal congestion. Nasal saline washes may help remove mucus and naturally soothe the nasal cavities. Further evaluation may be helpful if fever becomes high, breathing difficulty occurs, thick yellow mucus continues for many days, or symptoms return frequently despite treatment.
