Drooling in Sleep – How can you prevent the unpleasant flow of saliva?

Sleep should be sacred and enable a relaxed start to the day. But if you wake up in the morning and notice next to you that the pillow is damp again and a small puddle has formed next to your head, it will quickly be over with nice waking up moments.

The drooling during sleep is not only unpleasant , but also unhygienic and can cushion your burden with germs. In this guide you will find out how to prevent this flow of saliva and why you tend to drool while you sleep .

Drooling in sleep is understood as an increased flow of saliva during sleep. The man constantly produces saliva . Even if we do n’t eat before sleep , the fluid is produced and keeps the mouth moist. During the day, the excess saliva is swallowed.

When you sleep, however, it can happen that saliva flows out of your mouth. Depending on the intensity, only your mouth is a little more humid or a clearly noticeable puddle forms on the pillow.

The drooling in his sleep occurs not only in young children . This phenomenon can also occur in adults. The increased salivation is nothing unnatural. There are no pathological symptoms and it is not something you need to see a doctor with. At least not if only the drool occurs and no other signs, such as the racing heart before falling asleep, appear.

The clear flow of saliva indicates that you are sleeping particularly relaxed . This can be the case when the patient is very tired and the body has fallen asleep particularly deeply.

So it is nothing pathological and can affect everyone . But since it is often perceived as uncomfortable, you should consider the following causes and see whether they can apply to you. After that, you can take steps to prevent drooling while you sleep.


The drooling in sleep can be traced back to relaxed muscles . During sleep, the body relaxes and this includes the facial muscles. The jaw and tongue are no longer controlled, but rather blend in with the overall appearance of the body.

In the relaxed state, the mouth opens slightly and the saliva can escape. Whether your mouth is open or closed while you sleep depends on your sleeping habits .

That being said, the following causes may also be responsible for drooling while you sleep.


As the facial muscles relax, the sleeping position is crucial for the flow of saliva. If you sleep on your stomach, the saliva can flow practically unhindered onto the pillow . The mouth is slightly open and no longer represents a barrier.

This is also the case in the lateral position, when the head is tilted slightly to one side. The flow of saliva is a little more inhibited here, but drooling can still occur during sleep.

The supine position is to reduce a measure to drooling in his sleep. By learning to sleep on your back , you can get this problem under control.


Breathing through your nose is said to be the healthiest. The air we breathe is filtered and pathogens cannot easily penetrate. However, there are causes that prevent you from breathing through your nose. As an alternative, all that remains is to breathe through the open mouth . This, of course, encourages drooling in your sleep.

flu-like infection can be the cause of incorrect breathing . If you have a cold , your nose is blocked and you have no choice but to breathe through your mouth. This is open and the saliva can escape.

Another reason may be a crooked nasal septum . This makes it harder for you to breathe through your nose and to get enough oxygen, you automatically breathe through your mouth while you sleep. If you find during the day that it is difficult to breathe through your nose, have this checked by a doctor.


Pregnancy can unbalance some of the body’s processes . Hormones have a great influence and not only cause mood swings, but also alter the flow of saliva.

It is not uncommon for pregnant women to complain of increased saliva production. This phenomenon occurs especially at the beginning of pregnancy . From the second trimester onwards, however, the flow of saliva normalizes in most cases, so that the drooling during sleep also decreases.


Among the side effects of some medications also increased saliva production can count. During the night, the face is so relaxed that the saliva can no longer be swallowed and comes out of the mouth.

Antipsychotics and antibiotics are known to increase saliva production. After stopping the medication, the flow of saliva returns to normal.


Usually drooling shouldn’t be a cause for concern. In exceptional cases, however, it can also be an indication of a serious illness. If there is a swallowing disorder , the food intake is more difficult.

The body then reacts by increasing saliva production. This can be the case with diseases such as multiple sclerosis, muscular dystrophy or Parkinson’s. If you have other risk factors or signs that suggest these diseases, you should have your doctor check your sleep drooling.

However, these diseases as the cause of drooling in sleep are extremely rare and you should not panic and believe that you are affected.


The causes of drooling are many. Therefore, you should first check why the salivation occurs so strongly in you at night and take the appropriate countermeasures. There is no general solution; it must always be tailored to the causes.


Sure, if you have a cold, it is difficult to breathe through your nose and you will automatically breathe with your mouth. The saliva escapes through the open mouth and soils your pillow.

Therefore, the treatment of the common cold should be in the foreground. Allow yourself some rest and cure the cold. After that, drooling in your sleep is forgotten again.

Also, pay attention to whether an allergy is responsible for the nasal congestion. A house dust allergy can cause discomfort, especially during the night.


If you find it difficult to breathe through your nose, you don’t need to have an operation right away. For mild forms, autogenic training can provide enough relief to stop drooling while you sleep.

Relax before bed, close your eyes and mouth. Now you breathe consciously through your nose and concentrate only on your breathing.

In the long term, you should be able to breathe better through your nose and reduce mouth breathing while sleeping.


An unfavorable sleeping position can encourage the flow of saliva. If you find it difficult to learn a new sleeping position, you can use aids.

An orthopedic pillow helps your body adopt an ergonomic sleeping position. Your head no longer bends to the side or forward, but keeps its optimal position. This prevents the flow of saliva.

If you sleep on your back and use an orthopedic pillow for additional stabilization, it effectively combats drooling while you sleep.


Drooling while sleeping is uncomfortable. It can affect both children and adults , but it’s nothing to worry about. Because it only indicates that the body is sleeping particularly deeply and the facial muscles are relaxed.

As a result, the mouth is slightly open and the saliva can escape. By sleeping on your back and improving nasal breathing, the flow of saliva can be reduced.

The ENT doctor should only be consulted in very extreme cases and in connection with other symptoms of the disease.

In most cases, while sleeping drooling is embarrassing and stains the pillow, it is not a cause for undue concern . With small changes to your sleep, you can get the problem under control yourself.

Hello, I’m Jamie Clark, 32 years old, and I have been living in the USA for a few years.
Since I was a child, I have suffered from a house dust allergy, severely affecting me. I felt the effects both while exercising and while sleeping. Constant sneezing after getting up and difficult breathing were the consequences. The allergy has also developed into asthma, which is still a sporting restriction today.
