Why do you shiver when you fall asleep?

Many people will suddenly shake their bodies as if they were electrocuted before they fall asleep or fall asleep, what is the reason for this? The answers are varied: some say you're growing taller, some say you're deficient in calcium, and some say your nervous system is afraid of you dying and alarming you!

The researchers offer two plausible explanations.

The first explanation is that the sudden shaking of sleep is called "muscle jerk", the main reason is that the breathing rate decreases too much during sleep, and the brain thinks that the body is about to die, so it will send a pulse to wake the body, indicating that your body is not very good at this time. At this time, you should pay attention to adjusting your work and rest time to prevent overwork.

The second explanation is that it is just a glitch in the brain's work. When you fall asleep, the muscles of the whole body begin to relax, because the lack of a feedback signal causes the brain to mistakenly believe that this muscle relaxation is a dangerous signal for the body to fall, so it mobilizes the motor system to protect itself, resulting in muscle twitching. It is also rumored among the folk that sleeping and pushing the legs is growing taller.

However, there are also pathological muscle jerks. There are several main reasons for this phenomenon:

1. High pressure. At work, people who have strained relationships, heavy tasks, long-term overtime, often stay up late, and poor sleep quality are prone to this symptom. There are also people who get angry easily and are frightened.

2. Severe calcium deficiency. Low calcium causes the muscles and nervous system to be more excited, causing muscle spasm and nerve convulsions.

3. Liver and kidney weakness, lack of qi and blood. If it is not very strong every time, but the frequency is relatively large, it may be caused by the deficiency of liver and kidneys and the lack of qi and blood.

4. Symptomatic muscle twitching: If it is accompanied by headache, dizziness and other conditions, it is also pathological, and you should go to the hospital in time for brain CT or magnetic resonance to rule out brain diseases.

Finally, it is recommended that you soak your feet in hot water at about 40 degrees Celsius every day before going to bed (it is advisable to soak to the ankle joint), wait until the water is cold, and then pour hot water to maintain the water temperature. Soak for 15 to 20 minutes. Soaking your feet in hot water before going to bed can promote peripheral blood circulation, relax muscles and activate blood, and relieve spasms.

Why does my body suddenly shake when I fall asleep?

Because the human mind and body have already fallen asleep, and the consciousness suddenly awakens, the body does not wake up from the sleep mechanism for a while, and there will be a slight tremor.

This is normal, the brain will twitch involuntarily during deep sleep, and the brain is also active.

Because the brain thinks that the body is not moving because the body is dead, the brain sends out a shock wave to confirm it.

Shaking occasionally while sleeping is a normal physiological manifestation and there is no need to worry too much. Usually overworked, stressed, or low blood calcium in the human body can lead to long-term hyperactivity of muscles and nerves, causing muscle spasm and nerve convulsions.

The sudden shaking during sleep is called "nighttime myoclonus" and is a very common phenomenon. This phenomenon usually occurs during the light phase of sleep or during the transition from a pure state of sleep, such as from awake to sleep or from sleep to wakefulness. It usually only lasts a second or two, and most people don't remember experiencing this phenomenon when they wake up.

There are a variety of factors that can cause nocturnal seizures, including:

1.Fatigue: If you are overtired, your body will be more likely to shake while sleeping.

Mental stress: Mental stress can also cause night seizures, as it can cause the body to be in a state of tension.

3.Medications: Certain medications, especially antidepressants and antipsychotics, can cause nocturnal seizures.

4.Sleep apnea syndrome: Sleep apnea syndrome is a condition that affects breathing, and it can cause nighttime seizures.

In conclusion, nocturnal seizures are usually a normal phenomenon and do not cause for much concern. If you believe that this tremor is affecting your sleep or health, it is recommended that you consult a doctor or sleep professional for a more accurate diagnosis.

This condition is also known as sleep serum fibrillation, and it is due to a natural reaction of the large eggplant brain when it enters a deep sleep. The brain becomes "half-asleep", which causes the muscles to twitch, which causes the body to shake.

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.

1. Physiological causes:

For example, overwork, poor sleep quality, mental stress, lack of exercise, excessive exercise before bedtime, etc., may cause sudden shaking when sleeping, or a feeling of falling and stepping on the air, which may be physiological muscle twitching syndrome, and usually does not need to take measures**.

2. Pathological causes:

1. Hypocalcemia.

Calcium can maintain neuromuscular stability, while patients with hypocalcemia have a decrease in serum calcium levels, increased neuromuscular excitability, and symptoms such as tetany, muscle pain, fingertip numbness and pinprick sensation will occur, which will cause sudden shaking when sleeping;

2. Hyponatremia.

If the patient's blood sodium level decreases, the brain cells have abnormal function in regulating osmotic pressure, and brain cell edema may occur, causing muscle spasm throbs, stupor, coma and other discomforts, causing sudden shaking when sleeping;

3. Restless legs syndrome.

Discomfort in both lower limbs may occur during sleep at night, and symptoms such as unconscious shaking and periodic limb movements may occur when sleeping or quiet, which may be manifested as sudden and patient shaking during sleep, and anemia.

Pregnancy and other factors.

It may be because the brain doesn't know if the body is over, so it decides to put some electricity and let the body feedback whether it is still alive.

This sudden shaking is called a "hypnic jerk", also known as a "sleep start". The pacing response occurs when a person enters a sleep state, usually at the beginning of sleep (early stage), when the person's brain and body enter a relaxed sail state, and the breathing becomes slow and deep, but some muscles are still in a state of tension, which may be caused by the nervous system's loss of control over muscle signals, or because the muscles that suddenly relax are too strong.

When muscles have excess tension, they naturally relax before the person enters the deep sleep phase. However, before relaxing the muscles, the brain may mistakenly interpret this relaxation as a drop of the body, and then issue a command that directs the muscles to contract rapidly to avoid the body falling. This abrupt contraction is the pacing response.

Pacing is usually normal and not too much to worry about, but if it often interferes with sleep quality, or if it is accompanied by other symptoms (e.g., insomnia, difficulty breathing, etc.), it is recommended to see a doctor for evaluation and**. First code.

This sudden shaking is called "hypnic jerk" and is a normal physiological phenomenon. As you fall asleep, your body relaxes and your heart beats and breathes slower, but sometimes your brain mistakes you for an emergency such as a fall or loss of balance, and it gives instructions for your muscles to move and contract quickly, causing you to shake violently. This phenomenon usually does not need to be worried, as long as you maintain good sleep habits and regular work and rest, you can reduce the occurrence of this phenomenon.

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.
