What causes dry mouth and throat during sleep?
Disease description:
My husband always says he feels thirsty and wants to drink water when sleeping. It's not exactly thirst, just a dry mouth that needs moistening. I would like to ask, what are the reasons for having a dry mouth and throat during sleep?

Dr. He Haochen
The causes of dry mouth and throat upon waking may involve multiple factors:
1. Environmental factors: High indoor temperature and low humidity, especially when using air conditioning or heating without humidification, can cause evaporation of moisture from the oral mucosa, leading to dry mouth and throat.
2. Dietary factors: Consuming overly salty, spicy, or irritating foods in the evening, as well as insufficient water intake before bedtime, can reduce oral moisture and result in dry mouth and throat.
3. Personal habits: Sleeping habits such as mouth breathing and snoring can lead to moisture loss in the mouth, causing dryness and thirst upon waking.
4. Medical conditions: Chronic diseases such as diabetes and Sjögren's syndrome may affect the secretory function of the salivary glands, making dry mouth and throat a persistent condition.
To alleviate this symptom, it is recommended to maintain appropriate indoor humidity, adjust dietary habits, and pay attention to any potential underlying medical conditions. If symptoms persist, timely medical consultation and examination are advised.
