Waking up every morning with a stuffy nose but being fine during the day may be caused by vasomotor rhinitis, chronic simple rhinitis, allergic rhinitis and other reasons. 1. Vasomotor rhinitis: this disease may be due to hot and cold air stimulation of the nasal mucosa, so that the nasal mucosa is congested, nasal turbinate hypertrophy, and then nasal congestion. After the blood circulation in the nasal cavity is improved, the symptoms disappear after adaptation, and there will be nasal congestion when waking up every morning but nothing happens during the day. 2. Chronic simple rhinitis: chronic simple rhinitis or nasal polyps, sinusitis patients will appear turbinate enlargement, nasal mucosa congestion, swelling, resulting in nasal congestion, alternating or intermittent nasal congestion, sticky nose and other symptoms. 3. Allergic rhinitis: As the morning nasal nerve sensitivity increases, stimulated by allergens, resulting in nasal mucosal stagnation and swelling, resulting in nasal congestion, itchy nose, sneezing, or temporary loss of smell and other symptoms. After the blood circulation is accelerated after daytime activities, the inflammatory factors and mediators are consumed and metabolized, the stagnation will be reduced, and the nasal congestion will be alleviated during the daytime. If the patient wakes up every morning with nasal congestion but is fine during the day, he should consult a doctor in time to clarify the cause of the disease, and under the guidance of the doctor, take the appropriate treatment program.
