The Science Behind Drooling: Explaining Why We Drip While We Sleep

Saliva is produced in the salivary glands located in our mouth and helps to keep it lubricated, moist and assists in breaking down food. At night, as we sleep, our body produces less saliva, with reduced lymphatic and cardiovascular activity resulting in less efficient swallowing. This combination can lead to drooling during sleep.

While drooling is normal and often harmless, it can lead to skin irritation or infect the sinuses if it becomes excessive, especially for those who sleep on their stomachs. There are many strategies to stop excessive drooling, such as reducing saliva production, changing sleep position, and using saliva-absorbing pads.

From Snoring to Drooling: How Sleep Apnea Can Affect Your Nightly Habits

Sleep apnea is a serious disorder that can be a cause of excessive drooling. It causes the airway to become blocked, leading to pauses in breathing, waking up and leading to the inability to swallow saliva. This combination can increase the risk of drooling during sleep. Some of the common symptoms of sleep apnea include loud snoring and daytime sleepiness. Treatment for sleep apnea can also curb drooling by improving breathing and respiration during sleep.
