Drooling is expected in babies, who do not yet have full control over their mouths or swallowing muscles. But drooling is often embarrassing for children and adults. Many people may avoid discussing this symptom.
Drooling can occur for many reasons. Most people drool every once in a while. It is especially common while sleeping, when a person swallows less frequently. This can cause saliva to accumulate and seep from the sides of the mouth.
You would tell the truth or you would lie if a friend asks you if you drool oversleeping. The most common answer is no, because for some, it is embarrassing to imagine it in that situation.
Drooling while sleeping is usually frowned upon or can make you feel uncomfortable. But the reality is that it is not only common, but it can be an indicator that you rested very well.
The dream has several phases of more or less equal duration. The main phase is known as rapid eye movement (REM). During the REM phase, the body enters a deep sleep and we experience a restful sleep. In this stage, certain neurotransmitters are inhibited to avoid the muscular movements that would make us run away before a nightmare. Therefore, the famous drooling occurs when you get to deep sleep.
So, if you fall asleep and drool, you are achieving the quality of sleep, something that is very positive for your health.
