The body shakes suddenly while sleeping

This is a normal phenomenon, do not worry too much, this situation is not calcium deficiency, calcium deficiency is the performance of hand and foot cramps, limbs shaking, weakness, not convulsions when falling asleep.


To understand this problem, we can take an example first. Many athletes shake their hands and feet to relax their muscles after strenuous exercise, especially anaerobic exercise. Shaking muscles is conducive to releasing lactic acid stored in muscle tissue after strenuous exercise. Similarly, we need to know that sleep is not only a brain phenomenon, It is a physiological phenomenon that requires the whole body to participate.


Sensory organs in sleep, such as ears and nose, are in a dull state, and muscles also need sleep, which is manifested as deep relaxation of muscles.


When in the state of sleep, all aspects of the body are gradually relaxed, muscle is no exception, when the muscle relaxes to a certain extent, it will automatically twitch up, just like the athlete shaking hands and feet, its role is to make the muscle reach the state of deep relaxation.


So this kind of limb twitch is very normal, in the case of overwork during the day, sleep at night will be more prone to this situation, so it is normal, there is no need to worry.
