Sleep is one of the best activities you can do for your body.
Everyone needs sleep. But according to research, most people do not need 8 hours of rest.
REM (rapid-eye movement) sleep provides higher quality rest than other sleep stages. So, you are more relaxed when you awake. You may also drool during your nap which reflects how comfortable you were.
Drooling and other side effects hint at the quality of your sleep.
Are there other reasons people drool?
Yes. One of the primary reasons for opening your mouth while asleep is breathing problems.
These issues occur because of either nasal congestion or excessive salivation. A symptom of nasal congestion is snoring and sleep apnea. But excessive salivation (sialorrhea) relates to heartburn and gastroesophageal reflux disease.
In general, it is not necessary to treat drooling that happens while you sleep.
How much REM sleep is healthy, according to research?
REM takes up 20-25% of rest cycles for adults and 50% for infants. People often enter REM sleep within the first 90 minutes of falling asleep. Rest periods repeat, so it is normal to experience REM several times.
Why is REM sleep essential?
This sleep cycle stimulates brain areas needed for learning and making memories.
