The main reasons for dry throat at night are as follows: 1. The climate is dry, the patient sleeps with air conditioning on, or with floor heating or heating, the air is dry, the patient sleeps with dry throat at night. 2. The patient may have obstructive sleep apnea syndrome, the patient has poor nasal ventilation, hypertrophy of the tongue, narrow pharyngeal cavity, open mouth breathing during sleep, the air does not go through the nasal cavity wetting The air enters the respiratory tract directly through the oropharyngeal cavity, which also easily leads to a dry throat. For the above situation, it is recommended to put a humidifier in the sleeping place, drink more water at night before going to bed, and eat more sorbets during the day when the throat is dry. If there is still no significant improvement, it is recommended to go to the ENT clinic and let the doctor prescribe Chinese medicine preparations for pharyngitis for oral symptomatic treatment and nebulization treatment, which can also relieve dry throat and other discomfort.
