First of all, from a medical point of view, most people with sleep paralysis have too much mental stress during the day, causing qualitative fatigue of brain thinking. And do you habitually put your hand on your chest when you sleep at night? Or like to cover your head with a quilt? If so, I suggest you change it, get used to sleeping on your right side or lying on your back, and keep breathing smoothly. This helps to keep your heart, blood and respiratory system in a certain regularity. Secondly, from the analysis of applied psychology, most of the causes of sleep paralysis are caused by psychological deficiency. First of all, you must make positive self-psychological hints, which is just a very common problem of poor sleep quality.
Suggestions:
Believe in the scientific attitude. You can drink a glass of milk before going to bed, or listen to relaxing music, and always keep a good mood and face problems optimistically and positively.
