The Problem of Drooling While Sleeping Should Not Be Ignored

Drooling while sleeping is a common phenomenon, but if it occurs frequently in adults, it may be a sign of certain serious health conditions.

Where Does Saliva Come From?

The process of saliva secretion is controlled by the autonomic nervous system, functioning involuntarily like the heartbeat. The salivary glands in the mouth are divided into major and minor salivary glands. There are three pairs of major salivary glands:

• Sublingual glands

• Parotid glands

• Submandibular glands

These salivary glands work continuously, keeping the oral environment moist, disinfecting, cleaning the mouth, and aiding digestion. In healthy adults, the amount of saliva secreted daily ranges from 1 to 1.5 liters, averaging about 30 ml per hour. Saliva secretion increases when eating or when the brain's nerves are stimulated.

Mouth breathing, stress, fatigue, or incorrect sleeping positions can all lead to drooling while sleeping.

When Should You Be Concerned About Drooling?

In children, this phenomenon is common as their oral muscles are not yet fully developed. However, if an adult suddenly experiences frequent drooling while sleeping, they should be aware of the following health conditions:

1. Oral Diseases

Pharyngitis, gingivitis, and maxillofacial inflammation can stimulate the salivary glands to produce more saliva, leading to drooling. Additionally, misaligned teeth, loose teeth, or discomfort from wearing dentures can also cause this condition. If the problem stems from oral health issues, timely adjustments can help improve the situation.

2. Facial Paralysis

Facial paralysis is a condition where the muscles on one side of the face become paralyzed, making it difficult to control saliva. If drooling is accompanied by a crooked mouth, immediate medical attention is needed.

3. Gastroesophageal Reflux Disease (GERD)

Abnormal stomach acid levels can trigger an increased saliva secretion reflex. People with GERD often experience drooling along with symptoms like acid reflux, heartburn, and chest pain.

4. Parkinson’s Disease

In Parkinson’s patients, swallowing function is impaired, causing saliva to accumulate rather than being swallowed in time. Additionally, nerve damage can stimulate excessive saliva production, leading to continuous drooling.

5. Cerebral Thrombosis (Stroke)

Blockages in cerebral blood vessels can impair the function of throat muscles, preventing the patient from controlling saliva while sleeping. If accompanied by symptoms such as a crooked mouth, saliva flowing in one direction, and difficulty closing the eyes, immediate medical attention is required.

6. Arteriosclerosis

Arteriosclerosis reduces blood flow to the brain, leading to oxygen deficiency and affecting facial muscle function. Middle-aged and elderly individuals with high blood pressure, high cholesterol, or diabetes should be particularly cautious.

How to Improve Drooling While Sleeping

1. Adjust Your Sleeping Position

Sleeping on your back can help reduce drooling, balance the development of different body organs, and support better breathing. Avoid sleeping on your stomach or staying in one position for too long. A U-shaped neck pillow can help support the neck and maintain a proper sleeping posture.

2. Maintain Oral Hygiene

Practice daily oral care by rinsing your mouth after meals, brushing your teeth in the morning and evening, using fluoride toothpaste, and flossing at least once a day to clean between teeth. If you have oral health issues, address them promptly to prevent long-term consequences.

3. Adjust Medications

If drooling is related to medications, consult your doctor to explore alternative options. However, do not change or stop taking prescribed medications without medical advice.

Drooling while sleeping may be normal in some cases, but if it persists, pay attention to warning signs of underlying health conditions and seek medical evaluation when necessary.
