People who have entered light sleep, why do their bodies shake from time to time?

Why do people often shake when they are in light sleep? It's really not superstition, it's scientifically based. When people enter light sleep, their bodies often inadvertently convuls.

Many people's understanding of this is almost to be pressed by ghosts, epilepsy or body growth, and some people even give the explanation that the brain uses this way to test whether you are dead. What exactly is the reason? In fact, scientists have already given a conclusive conclusion a long time ago, but many people prefer to believe in superstitious events rather than believe in scientific truth, so let's find out together!

In general, body shaking occurs in the early stages of sleep, and often body shaking will wake up a person who is about to fall into a deep sleep. If a person falls asleep in a very private environment, he may feel very frightened when he is suddenly awakened, so he may associate superstitious events, but in fact, this is just a natural reaction of the body, just like burping when you are full, and sneezing when you have an allergic nose.

Scientists say that this involuntary shaking of the body is generally determined by the muscles. Since many people have been spending hours in a high-tension environment, their muscles are quite tense, and this is finally time to relax. The muscles also stretch slowly, which is medically known as hypnotic muscle jerk.

There is no correlation between the ghost press and the superstitious incident and whether it was awakened by an unknown creature.

After all, scientists have not confirmed to humans that there are ghosts and gods in life, and even the British "Approaching Science" has revealed that there are no ghosts and gods in this world. Therefore, the phenomenon that can be explained by ghosts and gods can actually be almost defined as the development of human scientific and technological civilization is still very slow. However, there have been many superstitious incidents that have been scientifically proven, but there are still many people who still have inherent thoughts.

What do you think is the cause of the sudden shaking?

This is called hypnotic jerking disorder. It is because people are in a highly tense environment before going to bed, and their muscles are tense, and when they are sleeping, their muscles begin to relax, and then there will be a situation of shaking.

When people are in a high-pressure environment for a long time, the muscles will be very tight, and the muscles will slowly stretch when relaxed.

The brain is testing if you are still alive, so it sends a pulse to awaken the body; It can also be caused by nightmares, and if this happens frequently, it is recommended to go to the hospital.

When some people go to bed at night, they suddenly shake their bodies violently, and it feels like they are about to fall. People who have this kind of situation are often very worried, worried about whether there is a sign of something serious in their body. Actually, this is a normal physiological reaction.

The sudden twitching of the body is actually a reaction called "muscle jerk". Because when people are about to sleep but have not yet entered deep sleep, the body will be in the "rapid sleep period" of sleep, at this time, because the body's breathing rate will decrease, and the amplitude of breathing will also increase, which will lead to the phenomenon of sudden muscle twitching. This phenomenon is normal under normal circumstances, and when it occurs occasionally.

Sometimes, when the body is in a state of tension and falls asleep due to the high level of mental stress during the day, it can also cause the body to suddenly have tics. Therefore, you only need to adjust your emotions and mentality in time to be able to alleviate it well.

Because this is a self-help function of the brain, it is testing whether the body has died, so people who have entered light sleep will often shake their bodies.

1. Calcium deficiency in the body causes muscle spasms.

Calcium deficiency doesn't just lead to bone loss in our body, resulting in bone health being compromised. When the body is deficient in calcium, the nerves and muscles of the person will be in a state of excitement, and there will be continuous pumping and muscle spasms when sleeping. Therefore, if you have frequent muscle twitching while sleeping, it may be a cause for concern.

2. Brain diseases.

If there are frequent hypnotic tics, headaches, dizziness, nausea and other conditions will occur when you wake up, which may indicate that there is a problem with the brain, such as tumors, sequelae of traumatic brain injury, degenerative diseases and other brain diseases. This is a signal from the brain that the red light has been lit up in good health, and you need to go to the hospital for a check-up as soon as possible. You should go to the hospital as soon as possible for a CT or MRI examination of the brain, and it is clear that **.

3. Lack of oxygen to the brain.

There are some pathological muscle twitches caused by lack of oxygen to the brain, especially for middle-aged and elderly people, who are more likely to shake when sleeping at night. Because when the human brain is deprived of oxygen, it will affect the cerebral arteries in the brain, which will lead to the appearance of cerebral arteriosclerosis. Therefore, when you find that the elderly in the family have body shaking when sleeping, and the number of occurrences is relatively frequent, then you need to be alert to whether it is a warning of cerebrovascular disease.

4. Sleep tics are a kind of involuntary twitching of rapid muscles that are not controlled by the will, which is a physiological reaction.

This is the same as eyelid twitching and hiccups, which may be related to fatigue and mental stress before falling asleep, and the nerves in the brain are in a tense state, so it may cause convulsions. Or exercise before bedtime or for some reason causes muscle tension, and the muscles begin to relax after falling asleep, which can also cause convulsions. It is not directly related to whether the body is healthy or not.

5. Restless legs syndrome.

Restless legs syndrome is a type of sleep-related movement disorder and is a common sensory disorder of the nervous system. The main symptom is extreme discomfort in both lower limbs during sleep at night, which is manifested as obvious tingling, burning, and soreness, and a feeling of suspension before falling asleep, which seriously interferes with the sleep process.

This is an unconscious muscle twitch, which is manifested as a sudden shaking of the body when you just fall asleep, and it is usually accompanied by a feeling of falling or stepping on the air for a week, which is a normal physiological manifestation.

It is caused by a cold in the body while sleeping, it is likely to be caused by a lack of calcium, it may be due to a lack of trace elements in the body, and it may be caused by poor sleep quality.

It is likely that the body is cold at the time of sleeping, which is caused by calcium deficiency, and it can be caused by the lack of trace elements in the body, and it can also be caused by poor sleep quality.

It may be because of a brain disorder that the body sends a distress signal, or it may be because you are very tired, or the lack of calcium in your body triggers muscle cramps and shaking.

Sleeping is one of the most relaxing things for people, but there are also various situations that can occur when sleepingFor example, when people are sleeping, their bodies suddenly shake, why is this happening?

Nerves

When we go to sleep, the brain is already resting, that is, in a state of inhibition, but sometimes part of our nervous system is still active, so this part of the nerve will send instructions from time to time, and this instruction will make our body respond, that is, shake a little. To put it simplyThe brain is asleep, but part of the nerves is not asleepThe nerves that are not asleep may command the body to shake.

Muscles

When we fall asleep, the brain falls asleep, but the rest of the body does not, including our muscles. Sometimes the muscles shake suddenly, and this is because it is still active, and since our brains are already asleep, this sudden shaking can be startling, butThis is actually a normal condition of the body

Psychological stress

Many people think that the sudden shaking of the body is due to excessive psychological pressure, but in fact, there is some truth to this statement. Modern people are very busy during the day due to excessive pressure on work and study, so when we fall asleep at night, the pressure in our hearts will make our body react to a certain extent. Common ones include poor sleep quality, insufficient sleep depth, and so on.

Since the body suddenly shakes, it will wake us up immediately, soIt's normal for this to happen occasionally, but it can affect our mental state when it happens often.

All in all, it is normal for our bodies to suddenly shake when we are asleep. If this happens too much, we need to check our body and pay attention to adjusting our mentality.

In fact, this is a type of hypnotic muscle jerk, also known as hypnotic tics. It is a normal physiological state in which an unconscious muscle twitch shortly after you fall asleep, accompanied by a feeling of emptiness, causing you to wake up suddenly.

This may be due to stress, or because the brain is asleep and the nerves are not yet there.

When a person is sleeping, the body will suddenly "shake", which should be a normal bodily response.

It's your nerves that you feel dead, so it's a reminder to see if you're still alive.

It is normal for the body to suddenly "shake" when sleeping, so don't worry too much.

It may be a physiological response to the muscles, it doesn't matter, don't worry.

It could be a sudden cold, or it could be a natural reaction from the body.

Reaction due to nerve compression.

It's a problem caused by a nervous twitch, and it's fine.

It's normal, so there's no need to worry about it.

I'm in this situation and I never understand what's going on?

In fact, for "when I was sleeping, I suddenly had convulsions and kicked my legs", which is commonly called "hypnic jerk or hypnagogic jerk" (hypnic jerk) in academic terms, many folk theories believe that this convulsions are because I am growing taller, but this statement is completely groundless, and have you investigated Yao Ming when he was a child and kicked down many walls?

Sleep twitching refers to the sudden and involuntary twitching of the muscles of the whole body when a person is about to fall asleep. This process is often accompanied by a sense of free fall or even a vague dream, which may lead to waking up. Sleep onset convulsions do not affect sleep, but if they are too frequent, they may lead to periodic limb movement disorder, which can become a "convulsive man" or "convulsive woman" and suffer from insomnia.

There are many opinions as to the reasons for this phenomenon. One theory is that when an individual goes from wakefulness to sleep, their heart rate slows, their body temperature drops, their breathing slows, and their muscles relax. The Reticular Activation System (RAS) is responsible for controlling this conversion process, and sleep twitching may simply be one of the companions of the REAS data error***.

An other, more interesting explanation is that the human brain evolved from the reptilian brain, and thus still retains a portion of the reptilian stress response pattern. When the muscles are completely relaxed, the brain thinks that we are in a free fall based on this stress response pattern, and out of the need to protect itself, the brain directs the muscles of the whole body to act immediately and try to grasp something in the process of falling. As a result, the already relaxed muscles suddenly tightened, triggering sleep convulsions.

I'm sure we've all encountered such a situation, that is, when we sleep at night, when we lie down well, our body will suddenly twitch, or when we sleep on the table, it won't take long for the soles of our feet to suddenly feel empty, so what is this kind of convulsions?

In fact, this symptom is medically called "hypnotic muscle jerk", but you can rest assured that this symptom is a very normal physiological manifestation, because when falling asleep, the body suddenly shakes and is accompanied by a strong sense of falling, this situation belongs to the unconscious muscle tremor, mainly in the arms, legs and even the whole body, and here is the body is releasing signals to you, after all, it is caused by the following reasons.

The first point is that the work pressure is high, you must know that if the work pressure is too high during the day, it will make people in a state of fatigue, and even lead to nervous tension in the human body, and this tension is often manifested in the night when you fall asleep, so that such a problem occurs.

The second point is liver and kidney deficiency, after all, if this symptom is not very intense, but the number of times is too much, it is likely to be due to the human body has liver and kidney deficiency, lack of qi and blood; Finally, there is the problem of calcium deficiency, because the lack of calcium in the human body will lead to low calcium content in the blood, which will cause mental excitement, which is why children are prone to muscle twitching problems when growing up, we should properly supplement calcium, and drink more bone broth, crucian carp soup and milk and other foods in the diet.

Why does the body suddenly shake when people are sleeping?

"Muscle twitching", when the breathing rate is low while sleeping, the brain thinks that the body is about to die, so it sends a pulse to wake the body up.
