Many people think that only children drool, but adults do. Under normal circumstances, we do not drool when we fall asleep, and if this phenomenon is often occurring, we must be vigilant. Drooling while sleeping may be caused by improper sleeping posture, such as sleeping on the table or sleeping on the side, which is easy to cause drooling.
However, if this is the case for a long time, it may be caused by some physical diseases and needs to be paid attention to.
-
Normal, you can sleep without opening your mouth.

We all know that when people are asleep, they sometimes drool. Why is that? Let's take a look.
When we fall asleep, our body's state of arousal naturally relaxes. This relaxation includes not only the muscles and nervous system, but also the salivary glands. The salivary glands are the organs responsible for producing saliva, but when we are asleep, our salivary glands have less salivary gland secretion.
This can lead to a feeling of dryness in the mouth, and it can also cause the saliva in the mouth to flow out of the mouth as well.
-
Another reason is that our throat structures become more flaccid during sleep. This laxity can cause saliva to flow out of the mouth more easily. At the same time, if we adopt the wrong sleeping position, such as sleeping with our head on our back, we will be more likely to drool out.

We often see people drooling unconsciously when they are asleep, not only children, but also adults and the elderly. What's going on here?
Saliva is actually a colloquial name for saliva, which is secreted by the salivary glands in our mouth. It moisturizes parts of our mouth and throat so that we don't feel dry.
During the day, saliva is constantly secreted, and we keep swallowing it into our stomachs without letting it flow out. In other words, we can control them with our consciousness. When we go to bed at night, our body and mind are in a state of complete relaxation, and the role of consciousness is basically non-existent, so we can't consciously swallow saliva into our stomachs, so sometimes it will flow out unconsciously.
Of course, not everyone drools while asleep. Because when we are asleep, the activity of the salivary glands is much less than when we are awake, and combined with our unconscious swallowing movements and the sealing effect of the lips, saliva generally does not flow out. However, if we accidentally catch a cold and our nose cannot breathe, saliva will flow out unconsciously.
In addition, if you are too tired from working and studying during the day, and sleep too deeply and too well at night, you will not be able to close your mouth tightly and your saliva will flow out.
We may often see cute babies or elderly ** saliva. Babies drool because they can't swallow saliva yet, and as soon as there is more saliva in their mouth, they will involuntarily come out. The elderly are drooling because they are getting older, the functions of all parts of the body are declining, and the muscles around the mouth are relaxed.
This is a normal physiological phenomenon.
-
Saliva is there all day long, because saliva is saliva. Saliva is secreted by three pairs of salivary glands in the mouth: parotid glands, submental glands and submandibular glands, because the salivary glands constantly secrete saliva to moisten our oral and throat parts, so that we do not feel dry mouth.
In that case, why is there no drooling during the day? It turns out that although saliva is constantly secreted, we also swallow it in the stomach frequently, and the more it secretes, the faster we swallow. Therefore, no matter how much or how fast saliva is secreted during the day, it only flows in the mouth and never flows outside the mouth.
Because, we humans are consciously acting to control it. However, it's a different story when you go to bed at night. When people are sleeping, the muscles of the whole body are relaxed, and the brain is resting.
As soon as I fell asleep, I forgot everything. If the conscious swallowing action of swallowing saliva into the stomach does not continue, it is possible to let the saliva slip out freely. So, does everyone drool when they fall asleep?
No, most people don't drool when they sleep. Because, when we fall asleep at night, the secretion activity of the salivary glands is also greatly reduced, and there is less saliva, and there are two lips as a line of defense to seal the exit, so generally speaking, there is no drooling. However, if you are tired of playing during the day, sleep too soundly and deeply at night, so that your lips are not closed tightly and show a slit, or if you breathe through your mouth due to poor ventilation through your nose, you will wake up and find a large puddle of water stains on your pillow.

Why do people fall asleep?
Satisfied. Scientists have found that falling asleep or waking up is the result of hormonal confrontation in the body. A team of French and Swiss scientists said they had demonstrated for the first time that an area at the front of the brain called the anterior visual nucleus (VLPO) of the lateral ventricles dominates whether a person is awake or asleep. >>>More
