Discouraged sleeping position
(1) curled up and slept. People who curl up to sleep are often insecure and nervous, and some people are introverted. This sleeping position of "prawn" puts great pressure on the spine, because sleep usually lasts for 7-8 hours, and the muscles of the neck and back are not relaxed for a long time, which will lead to backache and even nerve compression.
(2) Sleep with your arms on your back. The biggest harm of sleeping with the arm resting on the pillow is to press the radial nerve of the upper arm, which leads to numbness of the forearm, wrist and fingers and affects the blood circulation of the arm. You will feel uncomfortable when you wake up.
(3) sleep with your head covered. People who like to sleep with their heads covered seem straightforward and cheerful on the surface, but cowardice and shyness are usually buried inside. Covering in the quilt for a long time will seriously affect breathing, because the air circulation in the quilt is very poor, and soon the concentration of carbon dioxide will be high, and the concentration of oxygen will be low, which will affect the metabolism of the human body, and eyelid edema and listlessness will occur in the morning.
