Why do I suddenly shake when I sleep?

Some people say that this is because the brain finds that you haven't moved for a long time, and the brain suddenly has some confusion, and I don't know if you are still alive, so a signal is sent that when you are awakened, the brain is relieved and confirms that you are still alive; Some people say that this is a sign of a serious illness, and this situation has occurred many times, indicating that something is going to be a big problem with the body, which is not a good omen; Others say it's a ...... caused by the body growing taller

In fact, this phenomenon of sudden shaking and stepping on the air during sleep is called "hypnotic muscle jerking syndrome". When sleeping, the person will first enter light sleep, then deep sleep, and after about two hours of deep sleep, they will finally enter the REM phase.

When sleeping, the brain is at rest, and the cortex of the brain is inhibited. Because the brain is still resting, at this time, the advanced central nervous system will not get a response even if the subcutaneous center sends a signal, but when it comes to the rapid eye movement stage, due to the waking up, some of the subcutaneous central nervous system may have become active at this time, if the central nervous system sends out some exercise instructions, the muscles receive the instructions, they will unconsciously twitch, and the feet will suddenly have the feeling of stepping on the air.

During REM, the brain is resting and the body is in a state of low tension. But when a muscle moves somewhere in the body, the body tension will quickly recover, and the body will follow the muscle twitching, and suddenly shake, and you will wake up unconsciously.

Normal sleep can be divided into non-REM and REM sleep, which occurs during REM sleep and is a normal physiological phenomenon that occurs with REM sleep when the body suddenly shakes during sleep. Hypnotic muscle jerks are an involuntary muscle tremor that occurs when you fall asleep with a sudden shaking of your body, which can be accompanied by a sensation of stepping or falling. The reason for this phenomenon is related to hiccups, fatigue, nervousness, etc.

A sudden shaking during sleep, medically known as sleep cramps, is a normal physiological reaction in many cases. It is the human body muscles are still in a highly excited state during sleep, and it may also be a spasmodic episode caused by muscle excitement caused by over-excitation of brain cells. If epilepsy can be diagnosed, it is necessary to take the epilepsy medication regularly.

Patients should always be optimistic and avoid getting emotional.

Suddenly shaking, that is, at this time is already in a state of deep sleep, because the limbs are in a state of relaxation, if at this time once the nightmare situation, he will suddenly and violently move the limbs, and even wake up. At this time, you will also have nightmares, which is a classic symptom and some signs called REM sleep, so this is a normal phenomenon.

According to experts, it is because during deep sleep, the human nervous system does not know whether he is still alive or not, and it is automatically detected hahaha.

Sudden shaking of the body while sleeping is a common physiological phenomenon called hypnotic muscle jerking.

The phenomenon of <> suddenly shaking while sleeping is called "hypnic jerk", which is a physiological phenomenon and is very common. It usually occurs when a person first falls asleep, especially during rapid eye movement (REM) sleep.

Scientists have not yet reached a consensus on the cause of Hypnic Jerk, but there are some speculations and explanations:

Brain Mistake for Body Falling: Some scientists believe that before we fall into deep sleep, the brain may produce a signal that the body is falling, so it causes the muscles to contract quickly to avoid falling. This phenomenon is similar to when we wake up in a dream when we feel that we have fallen to the ground and then suddenly wake up with a dry pick.

Abnormal functioning of the motor nervous system: Another explanation is that there is a problem with the coordination of the motor nervous system (which is responsible for controlling muscle activity) with the rest of the nervous system during sleep, causing the muscles to contract abnormally.

The body's relaxation response: There is also an explanation that the body gradually relaxes before we go into deep sleep, but some people's bodies relax too quickly, causing the muscles to shake suddenly.

In conclusion, a sudden shaking during sleep is a normal physiological phenomenon and there is no need to worry too much. If you are concerned or have sudden and frequent seizures, it is advisable to consult a doctor for help.

This sudden shaking is known as "nocturnal convulsions" or "sleep muscle spasms" and is a very common phenomenon. It can be caused due to physical fatigue, overwork, mental tension, anxiety, etc. In addition, certain medications, drinks, and foods can cause nighttime seizures.

During sleep, the human brain constantly sends signals to control the body's muscle activity and keep the body stable. However, sometimes these signals are out of balance, causing the muscles to contract briefly, resulting in the phenomenon of nocturnal seizures. This phenomenon usually does not cause any harm to the human body, but if night seizures occur too frequently or for too long, they may affect the quality of sleep and even cause sleep disorders.

If night convulsions seriously affect the quality of sleep or cause physical discomfort, it is recommended to seek medical attention in time, seek the advice of a professional doctor and ** do not wither.

Our limbs are mainly controlled by the cerebral cortex, which inhibits the activity of the muscles of the limbs when we go to sleep. However, at this time, the muscles and nerves will have some spontaneous movements, and when sleeping, the blood circulation of the human body is slower, and the small muscle movements will be more obvious.

Therefore, body shaking is a normal phenomenon, don't pay too much attention to it, usually pay more attention, it may also be caused by calcium deficiency. If there are frequent occurrences, it is recommended to visit offline hospitals, and give targeted treatment after clarifying**.

1. Physiological factors: common include excessive fatigue, lack of sleep, etc., at this time, the brain is in a state of inhibition and convulsions, which are manifested as physiological myoclonus, which are transient convulsions, which will not last, and the symptoms can be improved after rest.

2. Calcium deficiency: due to vitamin D deficiency, hypoparathyroidism and other factors, symptoms of convulsions can also occur, and can also be accompanied by muscle cramps, numbness of hands and feet, dryness, rough hair, muscle pain and other symptoms. Laboratory calcium tests can confirm the diagnosis.

If it is in the acute stage, it is necessary to take rescue measures immediately, quickly correct the symptoms of convulsions by intravenous infusion of calcium gluconate, etc., and take drugs containing calcium carbonate, vitamin D, calcitriol and other ingredients under the guidance of a doctor**. After calcium supplementation, the symptoms disappear.

3. Seizures: The causes of epilepsy are related to genetics, trauma, infection, drugs, tumors, etc., which cause abnormal discharge of neurons in the brain, and epilepsy symptoms occur, and seizures can be accompanied by convulsions, respiratory arrest, confusion, increased saliva, dilated pupils and other symptoms, and should be treated in time.

When you are just about to fall asleep, it is a kind of physiological myoclonus, which is prone to seizures after exertion, fatigue, and insomnia, and the symptoms can be improved by resting.

In addition, it may be due to electrolyte imbalance, hypoglycemia, anemia, cerebral ischemia, hypoxia, nocturnal apnea syndrome, etc., which can lead to a lack of oxygen to the brain, and the symptoms of sudden shaking during sleep may occur, and the corresponding factors need to be corrected to improve the symptoms.

It can also be caused by seizures, which are prone to seizures at night and require an electroencephalogram to confirm the diagnosis. In the case of seizures, the appropriate antiepileptic ** may improve symptoms.

Sudden pumping while sleeping may be caused by non-disease factors such as age, muscle fatigue, and nerve excitation, or it may be caused by diseases such as hypocalcemia, epilepsy, and brain diseases.

1. Non-disease elements.

1. Age: If a young infant suddenly twitches during sleep, this is a common normal physiological phenomenon, and it is generally believed that this is the corresponding relationship between the brain learning or consolidating nerves and muscles, and this learning process is easier to complete in sleep without external interference.

2. Muscle fatigue: If you have carried out strenuous exercise or heavy physical labor during the day, the muscles are in a tense state, and you have not fully stretched before going to bed, the muscles are difficult to adapt to the sudden relaxation state during sleep, and you may have sudden convulsions. Patients are advised to rest properly during the day to relieve fatigue and to stretch well before and after exercise to reduce the occurrence of muscle twitches.

3. Nervous excitability: If you drink coffee, strong tea and other drinks that can improve nervous excitability before going to bed, or if you are in a high mood and more excited before going to bed, when you fall asleep, the excitability of the cerebral cortex decreases, but the subcortical nerves remain excited, and the muscles will contract and twitch without the control of the brain. This tic usually occurs at the moment when you are about to fall asleep, and as the sleep deepens, the excitability of the subcortical nerves gradually decreases, and the symptoms improve.

This is also a normal physiological phenomenon that can calm down before bedtime and reduce dietary intake to reduce the occurrence of tics.

Second, the disease ** element.

1. Hypocalcemia: The growth and development of adolescents, pregnant women feeding the fetus or the elderly osteoporosis can easily lead to calcium deficiency in the body, increase muscle excitability, and be prone to spasms, especially at night, and usually have numbness or tingling in the hands and feet, as well as anxiety, depression and other bad emotions. Patients with this disease should be given intravenous calcium gluconate infusion to correct hypocalcemia in the acute stage; If hypocalcemia is chronic or mildly symptomatic, calcium can be replaced with oral calcium tablets.

2. Epilepsy: If epilepsy occurs briefly during sleep, it can be manifested as a sudden convulsion, and can be accompanied by symptoms such as numbness of the limbs. Patients with this disease can use phenytoin and carbamazepine antiepileptic drugs as prescribed**; Surgery**, such as resection of the epileptic lesion, corpus callodotomy, etc., may also be considered.

3. Brain diseases: cerebral infarction, cerebral thrombosis, tumors and other brain diseases may affect the blood supply of the nervous system, or compress the central nervous system, and the excitability of the cerebral cortex is reduced during sleep, which is more likely to have abnormal manifestations of the nervous system and convulsions. If the convulsions are frequent, and there are many discomforts such as dizziness and headache during the day, it is recommended to go to the neurology department as soon as possible for brain CT, MRI and other examinations to confirm the brain lesions, and carry out ** in time.

Sudden convulsions during sleep are a common physiological phenomenon in most cases, and there is no need to be overly nervous without affecting the quality of sleep. However, if the seizures persist for many days, the seizures become more frequent, seriously affect normal sleep, or are accompanied by uncomfortable symptoms such as headache and dizziness, you need to see a doctor in time.

When sleeping, sometimes there will be a sudden shaking, this phenomenon is mostly normal, is a normal sleep physiological phenomenon. There will be shaking from time to time throughout the sleep cycle, so don't worry too much, the reasons are as follows: 1. It may be caused by pathological causes, the common disease is epilepsy, epilepsy is due to the abnormal discharge of the brain caused by the involuntary twitching of the limbs or body, in this case, you can do EEG examination, do 24 hours of sleep EEG, that is, you have to wear the EEG machine to sleep overnight, if you shake, there are corresponding changes in the EEG, Basically, it is possible to determine whether it is caused by epilepsy.

Second, the common situation is low calcium, the elderly, children, pregnant women are particularly prone to low calcium, calcium ions can mainly maintain muscle excitability, calcium deficiency is easy to cause muscle spasm, resulting in limb shaking or body shaking. 3. If the temperature in the room is too low, the limbs or body will also have muscle spasms and shaking after being cold. The pathological cause is mainly related to epilepsy, which can be identified by electroencephalogram, and electroencephalogram can be identified, so there is no need to be too nervous.

Sudden shaking during sleep may be related to factors such as excessive exercise, calcium deficiency, and rapid growth and development.

1. Excessive exercise. Some people exercise too much during the day, including over-fitness during the day or overwork for a long time, which will cause their muscles to be over-tensed, and when sleeping, their muscles are in a relatively relaxed state, and there will be reflexive and involuntary limb shaking, which is normal, and you don't need to worry too much.

2. Calcium deficiency. Calcium deficiency in some elderly patients and menstruating women can also cause hypocalcemia, and in this case, they are prone to increased muscle excitability, so there will be sudden shaking of the limbs when sleeping. It is recommended that calcium supplementation can be appropriate to alleviate symptoms.

3. Growth and development are too fast. In life, if the growth and development of adolescents is too fast, it may also lead to a sudden increase in the demand for calcium in the body, which will lead to hypocalcemia, which will lead to an increase in muscle excitability, which in turn will cause symptoms such as sudden shaking during sleep. At this time, it is recommended to supplement calcium and eat more foods with high calcium content, such as fish, milk, lean meat, etc.
