In a person’s life, sleep accounts for nearly one-third of the time. Good sleep can fully relax the body and is good for health. The first step in sleeping is to close your eyes. I believe many people know that the fish is squinting when sleeping. Is it necessary to close your eyes when you sleep? Do you want to sleep with your eyes closed?
It turns out that when a person is asleep, the brain’s high-level nerve center is suppressed, the brain no longer controls the eyelids, and the muscles that control the eyelids are not working properly; closing the eyes is still a kind of self-protection measure: closing the eyes can block light stimulation and close The eye can keep your eyes moist enough. So people sleep with their eyes closed. Of course, some people are slightly squinting when they sleep, but this is really not a good thing. Under normal circumstances, it is caused by low tension of the orbicularis muscle, insufficient relaxation of the diaphragm, acute facial neuritis, congenital malformation of the orbicularis muscle, facial paralysis, and excessive eyeball.
