Introduction
In general, drooling during sleep may be caused by improper sleeping posture, inadequate oral hygiene, misaligned teeth, oral ulcers, gastroesophageal reflux, and other factors. Treatment options include general measures and medication. To prevent drooling during sleep, it is important to maintain proper sleeping posture, practice good oral hygiene, undergo regular dental checkups, and avoid excessive fatigue.

In general, drooling during sleep may be caused by improper sleeping posture, inadequate oral hygiene, misaligned or missing teeth, oral ulcers, gastroesophageal reflux, and other factors. If discomfort occurs, it is advisable to seek medical attention promptly. Specific explanations are as follows:

1. Improper Sleeping Posture

When the head is positioned too low during sleep or when lying on one side compresses the parotid gland, saliva may naturally flow out after secretion, resulting in drooling during sleep. Adjust your sleeping posture appropriately, use a suitable pillow, and avoid prolonged lateral positioning that compresses the parotid gland.

2. Inadequate Oral Hygiene

If brushing before bed does not thoroughly clean the mouth, food residues can stimulate saliva production, leading to drooling during sleep. Brush teeth thoroughly every morning, evening, and before bedtime, and use dental floss or an oral irrigator to clean between teeth.

3. Misaligned or Missing Teeth

Misaligned or missing teeth due to genetic or other factors can impair the mouth's ability to close properly, causing drooling during sleep. Regular dental check-ups and maintaining good oral hygiene are recommended.

4. Oral Ulcers

Oral ulcers are associated with factors such as reduced immunity and vitamin deficiencies. Inflammation can irritate the oral mucosa, increasing saliva production and causing drooling during sleep. This may also be accompanied by symptoms like oral pain, redness, and swelling. Patients are advised to follow medical guidance in using medications such as oral ulcer powder, cydiodine lozenges, or Huanglian Shangqing pills to relieve symptoms.

5. Gastroesophageal Reflux

Delayed gastric emptying, weakened esophageal motility, and other factors may lead to gastroesophageal reflux. Stomach acid flowing back into the esophagus or mouth may result in drooling during sleep, often accompanied by symptoms such as acid regurgitation and heartburn. Under medical supervision, patients may take medications such as omeprazole enteric-coated capsules, hydrotalcite chewable tablets, or domperidone tablets for treatment.

In daily life, it is important to maintain proper sleeping posture, strengthen oral hygiene, undergo regular dental check-ups, and avoid excessive fatigue.

Is sleeping on the ground good or bad for your health?
The ground is relatively hard and lacks proper support. When sleeping on the floor, the body comes into direct contact with a firm surface, preventing effective relaxation of areas such as the lower back and neck. This can easily lead to muscle tension and stiffness. Over time, it may contribute to conditions like lower back strain or cervical spondylosis, particularly affecting individuals who already have joint problems. Additionally, the floor tends to be colder in temperature and more prone to harboring bacteria and dust mites, increasing the risk of the body getting chilled during sleep.
