Patients who have a bit of nasal congestion in the morning may have acute rhinitis or cold caused by cold during sleep, or some patients may have allergic rhinitis factors that cause nasal congestion, sneezing, runny nose and other related symptoms. The most direct cause of nasal congestion symptoms is inflammation or allergic disease factors that cause congestion, swelling and edema of the nasal mucosa. If the degree of nasal congestion is relatively mild and can recover quickly on its own, no special treatment can be done for the time being, but attention should be paid to proper protection against cold and warmth and avoid contact with air pollution. If the symptoms of nasal congestion are persistent or even progressively heavy, nasal spray hormone drugs can be used accordingly to improve the symptoms; if the symptoms cannot be improved, it is necessary to go to the hospital for examination and diagnosis to exclude the related diseases.
