Drooling while sleeping can be normal, but it can also be due to other factors.

Normal causes
- Deep Sleep : During REM sleep, the body disconnects from swallowing and drooling occurs.
- Sleeping position : Sleeping on your side or stomach can cause saliva to leak.
Around the world, it’s very common for most people to lie when asked if they drool in their sleep, as this can cause them a lot of embarrassment, but there’s no reason to be ashamed, as this can be a sign that you’re in very good health.
For many people, it’s embarrassing to admit they drool while sleeping, as this could represent that they’re disgusting while in Morpheus’s arms. But we can tell you this isn’t a reason to feel embarrassed—quite the opposite. Let’s find out the details of this curious news…
What does your health say about you if you drool while you sleep?
Through a study conducted by specialist Jorge Abel Salinas, it was revealed that those who drool while sleeping are only experiencing the deep, restorative sleep phases, which means that if you do this frequently, you could be enjoying good health.

“Adults completely disconnect, shutting down their brain functions to allow for rest and recovery; they stop swallowing and swallowing, and saliva begins to leak out, causing the famous drooling of very deep sleep,” the specialist explained in his study.
Drooling while you sleep is a sign that you are in good health.
Specialist Jorge Abel Salinas also explained that if we drool while we sleep, it’s a clear sign that we’re getting good quality sleep, which indicates that this brings many benefits to our health, such as reducing depression, protecting our heart, improving memory, and strengthening our immune system.
“You shouldn’t be embarrassed about drooling, because it’s a natural occurrence. You just have to make sure you’re breathing properly and that you’re not experiencing sleep apnea (a breathing interruption),” the specialist added.
In addition, Salinas in his study also recommended that the entire population adopt good sleep habits, such as sleeping at least 8 hours a day, going to bed before 10:00 pm, eating well, and drinking plenty of water. This is the only way to ensure that sleep provides significant health benefits.
So next time, don’t be embarrassed when they ask you if you drool in your sleep, as this is a good sign that you’re in very good health.
