Because the pediatric nasal passage is relatively narrow, the nasal cavity is shorter, and the nasal mucosa is rich in blood vessels, tender. During the fall and winter seasons, the temperature changes in the morning and evening, the pediatric nasal mucosa is easy to congestion and edema, which further aggravates the narrowing of the nasal cavity, thus appearing nasal congestion and airless symptoms. If there is no fever, runny nose and other conditions, generally do not need special treatment. Parents can use a towel to apply hot compresses to the pediatric nose, or massage the sides of the nasal cavity, increase indoor humidity and other methods can improve this symptom.
