Drooling while sleeping is a common occurrence in both children and adults, and it is usually harmless. However, excessive drooling may indicate an underlying health issue. Several factors can contribute to drooling during sleep, including sleep position, infections, allergies, and certain medical conditions. During sleep, the facial muscles and swallowing reflex relax, allowing saliva to accumulate in the mouth. Side and stomach sleepers are more prone to drooling as gravity causes saliva to flow out of the mouth. Infections, such as pharyngitis, and allergies can also lead to increased saliva production and mouth breathing, resulting in drooling. Additionally, medical conditions like sleep apnea, GERD, and dental problems can be factors in drooling during sleep. While occasional drooling is typically not a cause for concern, consulting a healthcare professional is advised if drooling becomes persistent or excessive.

What You'll Learn
- Sleep position: Drooling is more likely when sleeping on your side or stomach
- Infections: Drooling can be caused by pharyngitis, epiglottitis, or other infections
- Allergies: Allergens can cause nasal congestion, leading to mouth breathing and drooling
- GERD: Gastroesophageal reflux disease can irritate the throat, causing excess saliva
- Sleep apnea: Obstructive sleep apnea can cause mouth breathing and increased saliva production
Sleep position: Drooling is more likely when sleeping on your side or stomach
Drooling during sleep is a common occurrence, and while it is usually harmless, it can sometimes be a warning sign of a health problem. One factor that can increase drooling is your sleep position.
Sleeping on your back typically minimises drooling. When a sleeper lies on their back, gravity generally causes any excess saliva they produce to stay in their mouth or travel to their throat. Sleeping on your back allows saliva to flow into the oesophagus and stomach, preventing it from escaping as drool.
However, if you sleep on your side or stomach, you are more likely to drool. Gravity can cause saliva to flow out of the mouth, and if you sleep with your mouth open, drool may be more likely to escape. Side and stomach sleepers may also experience more drooling due to the effects of gravity, as saliva can flow out of the mouth more easily in these positions.
If you are a side or stomach sleeper and want to reduce drooling, you can try changing your sleep position and sleeping on your back instead. You can also try to keep your mouth closed during sleep, such as by using mouth tape. Additionally, addressing any underlying health issues, such as allergies, infections, or sleep apnea, can help reduce drooling.

Infections: Drooling can be caused by pharyngitis, epiglottitis, or other infections
While drooling during sleep is common in both children and adults, it can sometimes be caused by certain infections. Pharyngitis, for instance, is a dental problem that can cause uncontrolled salivation during sleep. It is a throat inflammation caused by a viral or bacterial infection that can make swallowing painful, leading to excess saliva and drooling. Epiglottitis is another serious cause—an infection of the cartilage that covers the windpipe, which can cause drooling, a sore throat, and difficulty breathing. This condition is a medical emergency.
In addition to these, infections in the mouth, such as cavities, gum disease, or mouth ulcers, can also trigger excess saliva production. Your body produces more saliva as a natural response to irritation or infection in the mouth. If you have a cavity or infection in your mouth, the excess saliva produced by your body may come out as drool while you sleep.
Nasal congestion, which is often a side effect of cold viruses, flu viruses, or sinus infections, can also cause drooling. When you lie down, your nasal passages can become filled with excess mucus, causing a stuffy nose. This may cause you to breathe through your mouth while you sleep, leading to drooling.
Infections are not the only cause of drooling during sleep. It can also be caused by sleep position, medications, or other health issues. If you are a side or stomach sleeper, you are more likely to drool during sleep. Sleeping on your back may help minimize drooling. If you are experiencing a cold, allergies, or sinus congestion, these conditions can block your airways, causing you to breathe through your mouth and drool more than usual. Drooling during sleep is usually harmless, but if it occurs continuously, it may indicate an underlying health problem.

Allergies: Allergens can cause nasal congestion, leading to mouth breathing and drooling
While drooling during sleep is often harmless, it can sometimes be a symptom of an underlying health issue. One common cause of drooling is nasal congestion, which can be brought on by allergies.
Allergens such as dust, pollen, or animal dander can cause nasal congestion, or rhinitis, by irritating the nasal passages and causing them to swell and fill with mucus. This often gets worse when lying down, making it difficult to breathe through the nose. As a result, people may start breathing through their mouths, leading to drooling.
In addition to allergens, nasal congestion can also be caused by infections, such as colds, strep throat, or sinus infections. These infections can inflame the sinuses and block airways, further contributing to mouth breathing and drooling.
To reduce drooling caused by allergies and nasal congestion, it is important to address the underlying cause. Treating allergies, such as through medication or environmental changes, can help improve nasal breathing and reduce drooling. Additionally, sleeping on your back may also help minimize drooling, as gravity tends to keep saliva in the mouth when in this position.
While occasional drooling is typically not a cause for concern, excessive and frequent drooling may indicate a more serious problem. If you are experiencing persistent or severe drooling, it is recommended to consult a healthcare professional for guidance and potential treatment options.

GERD: Gastroesophageal reflux disease can irritate the throat, causing excess saliva
Drooling during sleep is a common occurrence, especially in children and the elderly. While it is usually harmless, it can sometimes indicate an underlying health problem. One possible cause of drooling during sleep is gastroesophageal reflux disease (GERD).
GERD is a condition that causes stomach acid to flow back up the oesophagus, which is the tube that connects the mouth and stomach. This regurgitation of stomach acid can irritate the mouth and throat, leading to hypersalivation and drooling. People with GERD may also experience dysphagia, or difficulty swallowing, which can make it feel like food is stuck in the throat. This can also cause drooling, as excess saliva builds up in the mouth.
The link between GERD and drooling during sleep is particularly strong. The relaxed state of the facial muscles and swallowing reflex during sleep can exacerbate the effects of GERD, leading to increased drooling. Sleeping on your back can help to minimise drooling by allowing saliva to flow into the oesophagus and stomach, rather than flowing out of the mouth. However, for people with GERD, sleeping on the back may trigger acid reflux, so it is important to consult a healthcare professional for personalised advice.
If you are experiencing frequent or excessive drooling during sleep, it is important to consider potential underlying causes. In addition to GERD, drooling during sleep can be caused by sleep position, infections, sinus problems, dental issues, digestive problems, or certain medications. Addressing these underlying issues may help to reduce drooling. However, if drooling is severe or continuous, it is recommended to consult a healthcare professional for guidance on treatment options.

Sleep apnea: Obstructive sleep apnea can cause mouth breathing and increased saliva production
Drooling during sleep is a common occurrence in both children and adults, and especially in the elderly. While drooling is usually harmless, it can sometimes be a warning sign of an underlying health problem.
Obstructive sleep apnea (OSA) is a sleep-related breathing disorder that causes frequent pauses in breathing during sleep. It is caused by an obstruction in the upper airway, often due to the relaxation and collapse of the soft tissues in the back of the mouth, tongue, or throat muscles. This depletion of oxygen interrupts the sleep cycle, causing the person to wake up frequently throughout the night.
Sleep apnea and drooling are closely linked. Mouth breathing is a common symptom of sleep apnea, and it is well known that breathing through the mouth at night can cause drooling. When a person sleeps on their back, gravity usually causes excess saliva to stay in the mouth or travel down the throat. However, when sleeping on the side or stomach, saliva is more likely to escape from the sides of the mouth.
Additionally, sleep apnea can lead to increased saliva production. When the airway is blocked, the body tries to compensate by producing more saliva to prevent the oral tissues from drying out. This excess saliva accumulates in the mouth, especially when sleeping on the side, and then runs out of the mouth, causing drooling.
If you are experiencing frequent drooling during sleep, it is advisable to consult a healthcare professional or a dentist, as it could be a sign of sleep apnea or other underlying conditions. They can guide you on the necessary steps to improve your sleep quality and overall wellness.
