What is the cause of the sudden shaking when sleeping

Have you also had this feeling, when sleeping, feel the body suddenly jerk a little, or legs suddenly shake; what is the reason? Is it a special hint from the body?

Physiological phenomenon

Both of the above-mentioned views have no exact scientific basis. Sleep twitching is a kind of rapid involuntary muscle twitching that is not controlled by the will, which is a physiological reaction, which is the same as eyelid fluttering and hiccups. It may be related to fatigue and mental stress before going to sleep, and the nerves of the brain are in a tight state, so it may cause twitching. Or exercise before going to bed or for some reason causes muscle tension, and after falling asleep the muscles start to relax, which can also cause twitching. There is no direct relationship with whether the body is healthy or not.

Related to dreaming

As the saying goes, there is something to think about and something to dream about, when people are asleep, the brain will still be in an active state, and if you dream at this time, or think of something unhappy, people will have a natural rejection of the psychology, wanting to escape from a bad situation, which is expressed in the limbs, the body suddenly shaking.

The brain's natural control of the body

80% of the body suddenly shake a little, occurring when people are about to enter a deep sleep, not yet asleep. In fact, the principle is very simple, the human subconscious and subjective intention are reminding themselves that it is time to go to sleep, but at the moment the brain has not yet entered a deep sleep, the brain is disturbed by two entangled emotions, there will be inhibitory tests to control the body suddenly shaking a little.

Calcium deficiency

If the body jerks and shakes frequently when sleeping, it may be related to the lack of calcium in the body. Low calcium will increase neuromuscular excitability, leading to muscle contraction and twitching.

Factors affecting sleep tremors

Body shaking during sleep is nothing but pathological factors and physiological factors. Pathological factors include: nocturnal convulsions caused by calcium deficiency; reflexes caused by neurasthenia; toxic reflections caused by intestinal parasites; limb hypoxia caused by circulatory system lesions, which leads to twitching. Physiological factors include: vegetative reflexes during sleep; limb reflexes triggered by deep sleep dreams.

Breaking the hypothesis

The first hypothesis is that the sudden shaking in sleep is called "muscle jerk", because the respiratory rate decreases so much during sleep that the brain thinks the body is dying, so it sends an impulse to awaken the body, indicating that your body is not functioning very well at this time. The second hypothesis is that it is a glitch in the brain's work. When you fall asleep, the muscles throughout your body begin to relax, and the lack of a feedback signal causes the brain to mistake this muscle relaxation for a dangerous message about the body's whereabouts, thus mobilizing the motor system to protect itself, resulting in a muscle twitch. It is also rumored among the people that sleeping stirrups are being grown taller.

Tip.

Occasional jittering is not harmful to the body and need not be too concerned about it; if it is caused by calcium deficiency, you can usually have more foods with high calcium content, such as milk, soy products, bone broth, etc., and take calcium tablets as appropriate, and soak your feet before bedtime to help relieve it.
