Why Do We Drool In Our Sleep?

what happens if you drool in your sleep

Drooling while sleeping is a common occurrence that can be caused by various factors, including sleep position, infections, sinus problems, and allergies. While it is usually not a cause for concern, it can sometimes indicate underlying health issues such as sleep apnea, GERD, or neurological conditions. In some cases, certain medications can also lead to increased drooling. Treatments for excessive drooling include antihistamines, botulinum toxin injections, and continuous positive airway pressure (CPAP) machines. Changing sleep positions and managing allergies can also help reduce drooling.

Characteristics Values
Sleep position Sleeping on the side or stomach can cause drooling due to the effect of gravity.
Mouth breathing Drooling is more likely when breathing through the mouth, which can be caused by nasal congestion, sinus issues, or allergies.
Excess saliva Certain health conditions, medications, and infections can increase saliva production, leading to drooling.
Weak muscles Relaxed facial and mouth muscles during sleep can contribute to drooling, especially with conditions affecting muscle control.
Neurological disorders Conditions such as cerebral palsy, Parkinson's disease, and multiple sclerosis can lead to drooling during sleep.
Sleep conditions Sleep apnea and bruxism (teeth grinding) are associated with mouth breathing and increased drooling.
Infections Throat and mouth infections can cause pain and swallowing difficulties, resulting in excess saliva and drooling.
Treatments Treatments include medication, therapy, botulinum toxin injections, surgery, and addressing underlying conditions.

Sleep position

While drooling during sleep is normal, changing your sleep position can help manage it. When you sleep on your back, gravity generally keeps saliva in your mouth or lets it travel to your throat. On the other hand, if you sleep on your side or stomach, gravity is more likely to pull saliva down toward the pillow, resulting in drooling. Therefore, sleeping on your back may help minimise drooling.

If you are a side or stomach sleeper, you can try switching to your back. However, you may need to get a new pillow to sleep comfortably. Side sleepers usually use a thick pillow, while back sleepers use a thinner one. To help yourself stay on your back throughout the night, you can place additional pillows along the sides of your body.

If you are a side or stomach sleeper who sleeps with their mouth open, you may be more likely to drool. You can take measures to breathe through your nose and keep your mouth closed while you sleep, such as using mouth tape or nasal strips.

Other ways to prevent drooling include staying hydrated, elevating your head while sleeping, using a humidifier at night, and treating allergies.

Infections

Drooling while sleeping is a common occurrence that can happen to anyone, but if it occurs frequently and excessively, it could indicate an underlying health issue. One potential concern is the risk of infections.

Bacterial infections are a possible consequence of drooling during sleep. When saliva pools around the mouth and on bedding, it can create a moist environment that is conducive to bacterial growth. This can lead to skin irritation and infections, such as perioral dermatitis, which is characterized by a rash and small, red bumps around the mouth. Bacteria can also cause respiratory infections if drool is inhaled into the lungs. This is especially concerning for people with weakened immune systems or underlying respiratory conditions.

To prevent bacterial infections, it is important to maintain good sleep hygiene and keep the sleeping area clean and dry. Changing bedding and pillowcases regularly, washing the face before sleep, and sleeping on a clean, dry pillow each night can help reduce the risk of bacterial growth. If you experience frequent drooling, using a humidifier in the bedroom can also help by adding moisture to the air and potentially reducing the amount of saliva produced.

In addition to bacterial infections, drooling can also increase the risk of viral infections, particularly herpes simplex virus (HSV) infections, such as cold sores and genital herpes. HSV is highly contagious and can be transmitted through contact with infected saliva. If you frequently drool during sleep and have HSV, you may experience more frequent outbreaks. Good sleep hygiene practices, including keeping your hands and face clean, can help reduce the risk of transmitting HSV.

Fungal infections are another potential concern. Candida, a type of yeast, can thrive in warm, moist environments, including bedding soiled with drool. This can lead to an overgrowth of Candida in the mouth, known as oral thrush, which can spread to other parts of the body. Symptoms of oral thrush include creamy white lesions on the tongue, inner cheeks, and throat, as well as pain and difficulty swallowing. Maintaining good oral hygiene and keeping bedding dry can help prevent fungal infections.

While rare, it is also possible for drool to cause eye infections if it comes into contact with the eyes during sleep. This can happen if you sleep on your side or stomach, with your face pressed into the pillow, allowing drool to pool around the eyes. Bacterial or viral conjunctivitis (pink eye) can result, causing redness, itching, and discharge. To prevent this, ensure that your bedding is clean and try sleeping on your back with a protective eye covering if you are prone to drooling.

Sinus problems

If you have sinus congestion, you may find that lying down makes it worse, and you may start breathing through your mouth. Mouth breathing can be caused by sinus problems, and it often leads to drooling. This is because the drool can more easily escape when your mouth is open.

If you are experiencing sinus congestion, there are several remedies that can help relieve your stuffy nose and reduce drooling:

  • Drink more water: Staying hydrated can help thin the mucus in your nose and sinuses, making it easier to breathe.
  • Elevate your head while sleeping: Propping yourself up on a pillow can help you breathe better and reduce acid reflux.
  • Try nasal strips: Adhesive nasal strips may help to widen your nostrils and improve breathing.
  • Use a humidifier at night: Humidifiers increase the water in the air, relieving congestion and making breathing easier.
  • Use decongestants: Taking decongestant medication at night can help to shrink and dry your nasal passages, making it easier to breathe through your nose.
  • Try nasal irrigation: Using over-the-counter saline sprays or neti pots can help to clear your sinuses and relieve stuffiness.

Medication

Drooling during sleep is often normal, but it can be a sign of a health issue. If you are concerned about drooling in your sleep, you should consult a healthcare professional. Depending on the severity of the condition, your doctor may recommend certain treatments.

If your drooling is caused by medication, do not stop taking it. Instead, speak with your doctor about your concerns and ask if they can recommend an alternative medication.

Botulinum toxin (Botox) injections have been used to treat drooling in people with neurological disorders. A doctor injects Botox into the salivary glands, usually with the assistance of ultrasound imaging.

Neurological conditions

Drooling is often a normal occurrence during sleep, especially in side and stomach sleepers, where gravity is more likely to pull saliva down toward the pillow. However, excessive and frequent drooling may indicate an underlying neurological condition.

Additionally, certain medications used to treat neurological conditions may also contribute to drooling as a side effect. For example, some antipsychotic drugs and medications for Alzheimer's disease can increase saliva production or affect muscle control in the mouth and throat.

If you are concerned about drooling in your sleep, it is important to consult a healthcare professional. They can evaluate your symptoms, rule out other potential causes, and recommend appropriate treatments or therapies to manage the condition. Treatments for drooling caused by neurological conditions may include medication to reduce excess saliva, motor therapy to improve muscle control, or, in severe cases, surgery to alter the salivary glands.

While occasional drooling during sleep is common, frequent and excessive drooling may be a sign of an underlying condition. Therefore, it is always advisable to seek medical advice if you have concerns or notice any other accompanying symptoms.
