when we sleep, parents always remind us not to sleep with our heads covered ~ why can't we sleep with our heads covered?
it is a bad sleep habit to sleep with your head covered in the quilt. It not only makes people not get enough rest, but also has adverse effects on health. People breathe all the time, inhale fresh oxygen and exhale carbon dioxide, so as to keep all parts of the body in good condition. However, when the head is drilled into the quilt to sleep, the thick quilt is like a wall, isolating the sleeper from the outside world, unable to exchange gas. As a result, there is less and less oxygen and more and more carbon dioxide in the quilt. Due to the lack of sufficient oxygen, the organs in the body can not work normally, which will eventually have adverse effects on the body. Because of lack of oxygen, people who sleep with their heads covered will suddenly feel chest tightness and shortness of breath, or be awakened by nightmares in the middle of the night, sweating all over, as if they have just experienced a fierce fight.
