Subtitle: Occasional drooling during sleep is normal—especially if you're a side or stomach sleeper. But frequent, excessive drooling (known as sialorrhea) can sometimes signal an underlying health issue.
Let me tell you about the first time I noticed I was drooling in my sleep.
I was in my late twenties, and I woke up with a wet pillow. I was embarrassed. I thought it was just a normal part of sleeping.
But then I started drooling more frequently. I started to wonder if it was a sign of something else.
