Why Do I Drool in My Sleep? Drooling during sleep is a common occurrence that may leave many feeling embarrassed or uncomfortable when they wake up. While it’s not usually something to be overly concerned about, it can be an indication of underlying issues. Drooling is often seen when someone sleeps on their side or stomach, but it can also be triggered by nasal congestion, allergies, sinus problems, and even certain medical conditions like sleep apnea or GERD (gastroesophageal reflux disease).
This article will explore why you may drool in your sleep, the causes behind it, and effective strategies to stop it. By understanding the factors that contribute to drooling, you can take steps toward managing and minimizing it for better sleep and overall health.
Drooling during sleep refers to the unintentional flow of saliva out of the mouth while a person is asleep. Saliva is naturally produced in the mouth throughout the day and night, playing a role in digestion, oral health, and the lubrication of the mouth. However, while awake, we generally swallow saliva regularly without thinking about it.
During sleep, our swallowing reflex slows down, and the muscles in the mouth and throat relax, making it more likely for saliva to pool in the mouth. If this saliva overflows, it can lead to drooling. While occasional drooling may not be a cause for concern, consistent drooling during sleep may indicate an underlying condition.
Why do I drool in my sleep?
There are several potential causes of drooling during sleep. Most of these causes are harmless and can be addressed with simple lifestyle adjustments. However, in some cases, drooling may be linked to more serious medical conditions. Understanding the factors that contribute to drooling will help in managing and potentially preventing it.
1. Sleeping Position
One of the most common reasons people drool during sleep is the position in which they sleep. Sleeping on your side or stomach increases the likelihood of drooling due to gravity. When you lie on your side or stomach, gravity works against you, allowing saliva to flow out of the mouth more easily. This is particularly common for individuals who sleep deeply or experience a relaxed muscle tone while sleeping.
2. Nasal Congestion and Mouth Breathing
If you have nasal congestion due to allergies, sinus problems, or a cold, you may find it difficult to breathe through your nose. As a result, you may resort to breathing through your mouth while sleeping. Mouth breathing can increase the likelihood of drooling, as it causes saliva to accumulate in the mouth, which may eventually overflow.
3. Allergies and Sinus Issues
Allergies and sinus problems can contribute to nasal congestion, which, as mentioned above, can lead to mouth breathing. Conditions such as hay fever, rhinitis, or sinus infections can block your nasal passages, making it harder to breathe through your nose. This forces you to breathe through your mouth during sleep, increasing the chances of drooling.
4. Sleep Apnea
Sleep apnea is a sleep disorder characterized by repeated interruptions in breathing during sleep. This condition often leads to snoring and can cause irregular breathing patterns that may contribute to drooling. In some cases, the increased saliva production due to sleep apnea can cause drooling while sleeping.
5. GERD (Gastroesophageal Reflux Disease)
GERD is a digestive condition where stomach acid leaks into the esophagus, causing discomfort and various symptoms such as heartburn. It is also known to increase saliva production, as the body produces more saliva to neutralize the acidic contents in the stomach. This increased saliva production can lead to drooling, especially when sleeping.
6. Neurological Conditions
Certain neurological conditions, such as Parkinson’s disease, cerebral palsy, or stroke, can affect muscle control in the mouth and throat. This can interfere with swallowing and cause saliva to accumulate in the mouth. Individuals with these conditions may experience chronic drooling, as their muscles may not be strong enough to prevent saliva from spilling out of the mouth.
7. Medications
Some medications can cause excessive saliva production as a side effect. These medications include certain antipsychotic drugs, medications for Parkinson’s disease, and some sedatives. If you are on any of these medications, it’s important to consult with your doctor about potential side effects, including drooling.
8. Sleep Disorders and Deep Sleep
People who experience very deep sleep stages may have reduced muscle tone in the mouth and throat, which increases the likelihood of drooling. During deep sleep, the body is more relaxed, and the muscles in the mouth, throat, and jaw loosen, making it easier for saliva to escape. For people who sleep deeply, drooling may occur more often.

How to Stop Drooling During Sleep?
If you find that drooling during sleep is affecting your quality of life, there are several methods you can try to reduce or eliminate the problem. The key to managing drooling is identifying the underlying cause and making appropriate changes to your sleep routine, lifestyle, or medical treatment.
1. Change Your Sleeping Position
As gravity plays a significant role in drooling, sleeping on your back may help reduce the likelihood of saliva flowing out of your mouth. Sleeping on your back prevents gravity from pulling saliva from your mouth and allows it to stay inside. Try using pillows to encourage back sleeping, or consider specialized pillows designed to help maintain this position.
2. Treat Nasal Congestion and Address Allergies
If nasal congestion is causing you to breathe through your mouth during sleep, addressing the underlying issues can help reduce drooling. Consider using a humidifier in your bedroom to keep the air moist, or try saline nasal sprays to relieve congestion. If allergies are a factor, over-the-counter antihistamines may help clear nasal passages and prevent mouth breathing.
3. Use a CPAP Machine for Sleep Apnea
If sleep apnea is contributing to your drooling, using a CPAP (Continuous Positive Airway Pressure) machine can help. CPAP therapy keeps your airways open during sleep, improving your breathing and reducing the likelihood of mouth breathing and drooling. Consult with a healthcare provider if you suspect sleep apnea is the cause of your drooling.
4. Manage GERD Symptoms
If GERD is contributing to excessive saliva production, managing the condition can help reduce drooling. Some dietary changes, such as avoiding spicy foods, citrus, and chocolate before bed, can reduce the symptoms of GERD. Additionally, taking medications such as proton pump inhibitors (PPIs) or H2 blockers, as prescribed by a doctor, can reduce acid reflux and prevent drooling.
5. Practice Swallowing Exercises
In some cases, drooling may be linked to poor muscle control in the mouth and throat. If you have a neurological condition that affects swallowing, you may benefit from practicing swallowing exercises or working with a speech therapist. A speech therapist can guide you through exercises to strengthen the muscles responsible for swallowing and prevent saliva from pooling in the mouth.
6. Adjust Your Medication
If drooling is a side effect of medication, talk to your doctor about alternative treatments or dosage adjustments. In some cases, the use of certain medications may need to be reevaluated to reduce unwanted side effects like drooling.
7. Elevate Your Head While Sleeping
If you have GERD or sinus issues, elevating your head during sleep can help reduce drooling. By keeping your head higher than your chest, you can prevent stomach acid from rising and alleviate sinus congestion, both of which can contribute to drooling.
8. Practice Good Oral Hygiene
Maintaining good oral hygiene may help prevent excessive saliva production at night. Brushing your teeth and using mouthwash before bed can ensure your mouth is clean, reducing the likelihood of drooling due to mouth breathing.
9. Consult a Doctor
If your drooling persists or is severe, it’s important to consult with a healthcare provider. A doctor can help diagnose any underlying conditions, such as neurological disorders or sleep apnea, and recommend appropriate treatment options.
