It is very common to wake up and realize that we have been sleeping with our mouths open and we are drooling. What we probably do not know is the reason for this, although there is no reason to worry, because it is a good sign.
Deep, restful sleep is a state in which a person is in the so-called REM phase (rapid eye movement). At this point, the body completely disconnects, the body enters a state of complete rest, and brain functions decrease.
In the REM phase, we stop swallowing, so we do not swallow saliva, but expel it. Therefore, many experts state that drooling during sleep is beneficial to health. According to the website Salud180, this means that the body is functioning properly and there is no sleep apnea or similar disorders.
