Drooling in your sleep is a common occurrence that can be caused by a variety of factors. While it is usually harmless, it can sometimes indicate an underlying health condition. The most common cause of drooling during sleep is the overproduction of saliva, medically known as hypersalivation or sialorrhea, which can be influenced by sleeping position, mouth breathing, health conditions, and medications. In this article, we will explore the various causes of drooling in your sleep and provide insights into when it may be a cause for concern.

What You'll Learn
It's normal, but may indicate an underlying issue
Drooling in your sleep is normal and is caused by the overproduction of saliva, which is called hypersalivation or sialorrhea. This can happen when your facial muscles relax and saliva dribbles out of your mouth, especially when you sleep on your side or stomach.
However, excessive drooling may indicate an underlying issue. For example, it could be a result of an infection, particularly in the sinuses, as your body produces extra saliva to flush out foreign invaders. Allergies can also cause blocked sinuses, leading to unwanted drainage in the form of drool. If you are experiencing allergies or a chronic sinus infection, it is recommended that you see a doctor for medication.
In addition, gastroesophageal reflux disease (GERD) can cause stomach acid to flow back up the oesophagus, which may irritate the mouth and trigger excess saliva. Other causes of hypersalivation include neurological conditions, teeth grinding, and obstructive sleep apnea. If you suspect you may have sleep apnea, it is important to consult a healthcare professional.
If you are concerned about drooling in your sleep, consider changing your sleeping position. Sleeping on your back may help curb drooling as gravity will pull the saliva down your throat, activating your swallowing reflex. You can also try using a wedge pillow to elevate your mouth or a chin strap to keep your mouth closed during sleep.

Sleeping positions can cause dribbling
Sleeping on your back is a quick way to resolve this issue. When you sleep on your back, the saliva will pool at the back of your throat and activate your swallowing reflex. However, sleeping on your back may not be feasible for those who are used to sleeping on their side or stomach. In this case, a wedge pillow that elevates your mouth and allows gravity to keep your saliva in your mouth can be used.
If you are a mouth breather, you are more likely to drool. Mouth breathing can be caused by a deviated nasal septum, which makes one nostril harder to breathe out of than the other. Nasal congestion, caused by a cold, flu, strep throat, sinus infections, allergies, or pregnancy, can also lead to mouth breathing. In addition, certain health issues such as neurological conditions, sleep apnea, gastrointestinal reflux disorder (GERD), and teeth grinding can cause mouth breathing.

Mouth breathing can cause dribbling
Mouth breathing can occur when your nasal passages are blocked. This can be caused by a deviated septum, enlarged adenoids, or nasal congestion due to allergies, colds, sinus infections, or pregnancy. When you lie down, mucus struggles to drain from your sinuses, causing congestion and making it difficult to breathe through your nose. As a result, your body may switch to breathing through your mouth, leading to dribbling.
In addition to blockages, mouth breathing can also be caused by sleep disorders such as sleep apnea, which causes temporary pauses in breathing during sleep. People with sleep apnea often breathe through their mouths to get enough oxygen, which can result in drooling. Acid reflux, a common symptom of gastroesophageal reflux disease (GERD), can also trigger excess saliva production and worsen when lying down, leading to drooling.
Certain sleeping positions can also contribute to dribbling. Sleeping on your side or stomach can increase the likelihood of drooling due to gravity, as saliva can more easily escape from the front or side of your mouth when it is facing downward. Changing your sleeping position to sleeping on your back may help reduce dribbling.
If you are experiencing frequent or excessive dribbling in your sleep, it is recommended to consult a healthcare professional to assess for any underlying conditions and provide personalized advice on how to reduce dribbling.

Health conditions can cause dribbling
While drooling in your sleep is normal, it can sometimes be caused by an underlying health condition. This could be a condition that causes excess saliva production, or difficulty breathing through your nose.
Sleep conditions
Obstructive sleep apnea (OSA) is a sleep disorder that causes short pauses in breathing during sleep. People with OSA often breathe through their mouths, which can lead to drooling. Mouthpieces used to treat OSA may also cause a build-up of saliva, making drooling more likely.
Nasal congestion
Nasal congestion, or rhinitis, occurs when your nasal passages swell and fill with excess mucus or snot, causing a stuffy nose. This can be caused by cold or flu viruses, sinus infections, or allergies. When you lie down, nasal congestion usually gets worse, leading to mouth breathing and drooling.
Neurological conditions
Neurological disorders such as Parkinson's disease, stroke, cerebral palsy, or Bell's palsy can result in swallowing disorders, also called dysphagia. These conditions can cause a loss of control of facial or oral muscles, creating problems with swallowing and leading to drooling.
Gastrointestinal reflux disorder (GERD)
GERD, or gastroesophageal reflux disease, is a condition where stomach acid flows back up the oesophagus. This can irritate the mouth and throat, triggering excess saliva and drooling. Acid reflux tends to worsen when lying down, so discomfort and drooling may be more pronounced during sleep.

Medication can cause dribbling
Drooling during sleep is a common occurrence that can be caused by various factors, including sleeping position, mouth breathing, health conditions, and, notably, medications. While occasional drooling is typically not a concern, excessive drooling may indicate an underlying issue.
Medication as a Cause of Drooling
Medications can indeed be a factor in drooling during sleep. While specific medications are not explicitly mentioned as a direct cause of drooling, it is important to consider the potential side effects of any medication that may contribute to this issue. For example, certain medications may cause dry mouth, which can lead to increased saliva production as a compensatory mechanism. Additionally, some medications may affect muscle control or relaxation, impacting the ability to contain saliva within the mouth.
It is always advisable to consult a healthcare professional if you have concerns about the side effects of any medication, including the potential for increased drooling during sleep. They can provide guidance on managing any adverse effects and advise on alternative treatments if necessary.
Furthermore, it is worth noting that in some cases, drooling during sleep may be a symptom of an underlying condition, such as neurological disorders or sleep disorders like sleep apnea. If you suspect that your drooling is related to an underlying health issue, seeking medical advice is essential to receiving an accurate diagnosis and appropriate treatment.
Remedies and Treatments for Drooling
While medication can be a factor in drooling during sleep, there are several strategies to manage and reduce this issue:
- Sleeping Position: Adjusting your sleeping position can be effective in reducing drooling. Sleeping on your back can help curb drooling as gravity prevents saliva from escaping through the mouth or sides.
- Treat Underlying Conditions: Address any underlying health conditions that may contribute to drooling, such as nasal congestion, allergies, or infections. Treating these conditions can help reduce mouth breathing and subsequent drooling.
- Mouth Taping and Chin Straps: Consider using mouth taping or chin straps to keep your mouth closed during sleep. These methods encourage nose breathing and can help prevent drooling.
- Wedge Pillow: Using a wedge pillow can help elevate your head and reduce the flow of saliva, making it easier to manage drooling.
- Medical Treatments: In more severe cases, medical treatments such as Botox injections into the salivary glands or speech therapy may be recommended to reduce drooling.
Remember, if you are concerned about excessive drooling during sleep, it is always best to consult a healthcare professional for personalized advice and treatment options.
