When a patient gets up in the morning with a non-ventilated nose, it is mainly considered to be related to the following aspects: first, it is likely to be the effect of seasonal factors, the air environment itself is dry, the air in the bedroom will also be dry, and at night the patient’s nasal mucosa secretion function is reduced, so the nose is particularly dry, and there will be a non-ventilated situation. Second, consider that the patient gets cold when sleeping, probably due to kicking the blanket or blowing the air conditioner, which causes the patient to have a non-ventilation of the nose. Thirdly, the patient may be exposed to dust mites when folding the blanket in the morning, which may induce the symptoms of allergic rhinitis and lead to the non-ventilation of the nose. Regardless of which of the above causes of morning nasal congestion is triggered, it is important to actively treat the symptoms.
