If you happen to drool during sleep, it’s a sign that your brain…

Drooling during sleep is quite common and usually nothing to worry about. It happens when saliva builds up in your mouth and instead of being swallowed, it leaks out – especially if you sleep on your side or stomach. The most common causes include:

– Mouth breathing (due to allergies, sinus problems, or a cold)
– Sleeping position (side or stomach position allows gravity to “do the work”)
– Deep sleep phases (muscles relax more, making it easier to drool)
– Certain medications or neurological conditions

Sometimes drooling is normal, but if it is frequent, profuse, or accompanied by:

– choking or coughing during sleep
– feeling tired during the day (possible apnea)
– sore throat or bad breath in the morning

…it’s better to seek out a specialist.
