Why Do People Drool When They Sleep?

Drooling during sleep is a common phenomenon, with potential causes including improper sleeping position, excessive excitement, oral diseases, spleen and stomach disorders, facial neuritis, or stroke. If the symptoms of drooling persist without relief, it is recommended to seek medical attention promptly and receive general and pharmacological treatments under the guidance of a doctor. Details are as follows:

1. Improper Sleeping Position:

Sleeping on a desk or in a lateral position can both lead to drooling. It is recommended to maintain a correct sleeping position, preferably lying slightly on the right side.

2. Excessive Excitement:

Physical fatigue, overuse of the brain, or consumption of certain medications may trigger nerve disorders, causing the brain to send incorrect signals during sleep, resulting in increased saliva secretion and drooling. It is advised to avoid physical and mental exhaustion, and prioritize rest.

3. Oral Diseases:

Poor oral hygiene or oral conditions such as mouth ulcers and periodontitis may stimulate saliva secretion through pain, leading to drooling. Maintaining oral hygiene, regular brushing or rinsing, and following doctor's instructions to use anti-inflammatory medications like Shuangliao Houfengsan or Kaihoujian Spray are recommended.

4. Spleen and Stomach Disorders:

Drooling in adults can be a manifestation of spleen and stomach dysfunction, commonly seen in reduced spleen and stomach motility, dampness retention, spleen and stomach damp-heat, or food stagnation and stomach heat rising. Improving spleen and stomach function and taking traditional Chinese medicine like Fu Ling, Bai Zhu, Shan Yao, and Dang Shen under doctor's guidance is advised.

5. Facial Neuritis or Stroke:

Sudden onset of drooling during sleep after facial exposure to cold, drafts, or colds should raise awareness of possible facial neuritis or stroke precursors. Medications like Prednisolone or Betamethasone, or surgical treatments, should be considered under doctor's guidance. If drooling is severe, immediate medical attention is necessary.

In daily life, avoid excessive excitement and minimize or avoid intake of spicy foods, acidic foods and beverages, and chewing gum, which may stimulate saliva secretion.
