Sudden shaking while sleeping

Nowadays, people are paying more and more attention to health. Many people know that some minor discomforts in the body cannot be ignored. Some minor problems may be signs of more serious diseases. Therefore, in life, we must not ignore some physical discomforts. Some people find that they or people around them suddenly shake when they sleep. What's going on?

Good sleep has a great impact on our health, but due to various reasons, our sleep will be affected by some conditions. Many people will experience sudden shaking when they sleep. What is going on? Is it serious? Let's take a look at the introduction below for this question.

When you sleep, your feet, hands, and even your entire body will shake involuntarily. This is a normal low-level nerve reaction. The movement of our limbs is controlled by the cerebral cortex. When the human body enters a sleep state, the cerebral cortex will inhibit the activity of the limb muscles, but at this time the muscle nerves will have some spontaneous movements. In addition, when you are sleeping at night, the blood circulation in the human body is slower, and the small muscle nerve movements will be more obvious. Sometimes it also manifests as a reaction to changes in dreams or the outside world, such as dreaming of falling off a cliff, being tripped, etc. But at this time it is not controlled by the brain, and our human body has no autonomous consciousness. It automatically shakes or kicks the legs down, similar to the "jump knee reaction" we are familiar with, so there is nothing strange about it.

What is the reason for the sudden shaking?

1. Fatigue: When the body is tired, the normal physiological functions of the muscles will change. At this time, a large amount of lactic acid will accumulate in the muscles, and lactic acid will constantly stimulate muscle spasms.

2. Electrolyte imbalance: Sweating a lot during exercise, especially in hot climates, will result in a large amount of electrolyte loss. The main components of sweat are water and salt. Salt is related to muscle contraction. Excessive salt loss can make muscles excited and cause cramps.

3. Cold stimulation: In cold climates, such as when exposed to cold water while swimming, especially if warm-up exercises are not adequate, muscles are prone to cramps. The main reason is that the muscles become more excitable due to the cold.

4. Physical weakness means that the body is in a very weak and tiny balance, unable to resist any external influence. The body balance will be destroyed if it is slightly cold.

The above is an introduction to the reasons for sudden shaking while sleeping. After reading the introduction in this article, you should know what is going on with sudden shaking while sleeping. Don’t worry too much when sudden shaking while sleeping occurs. If this situation occurs for a long time, you can go to the hospital to consult a doctor.
