Why do we sometimes shake suddenly when we are asleep?

Sometimes we may dream of a scene in our sleep. We will feel very scared, and at this time, we will kick the quilt, and we will feel it, which is a very normal phenomenon.

Sometimes our legs and arms will suddenly shake when we sleep, in fact, this shaking is called physiological muscle twitching, which is a physiological phenomenon, many people have experienced, the reason for this phenomenon may be excessive fatigue, daytime stress, excessive anxiety and tension, extreme physical fatigue or serious lack of sleep, which can make people enter the dream period early when sleeping, and the physiological phenomenon of sudden shaking of limbs.

Nerve reasons, when we sleep, the brain has rested, that is, in a state of inhibition, but sometimes some nerves in our nervous system are still active, so this part of the nerve will send instructions from time to time, which will make our body react, that is, shake. To put it simply, the brain is asleep, and some nerves are not asleep. Sleeping nerves may command the body to tremble.

A sudden shaking while sleeping may be caused by the following reasons:

1.Muscle vibration spasm: caused by physiological reasons such as overwork and stress, it is not necessary to **, but it is necessary to pay attention to regular work and rest. If accompanied by other symptoms, you should see a doctor promptly.

2.Low serum calcium: may be due to malnutrition, vitamin D deficiency, or disease, and can be relieved by calcium supplementation, vitamin D supplementation, or outdoor activities.

3.Epilepsy: Caused by a variety of factors such as head trauma, neurological disorders, genetics, etc., requiring anti-epileptic drugs**. If it is accompanied by symptoms of rapid weakness such as confusion, you should seek medical attention in time.

The phenomenon of sudden shaking while sleeping is called"Sleep tics", which is a common phenomenon, especially in the early stages of falling asleep or moving from light sleep to deep sleep. Here are some of the possible causes of sleep jerks:1

Sleep stage switching: When a person switches from one sleep stage to another, there may be a brief imbalance in the nervous system, resulting in a brief contraction of the body's muscles, which in turn causes shaking. 2.

Sudden muscle contractions: Sudden muscle contractions during sleep can also cause shaking. This condition may be related to abnormal or sudden nerve impulses in muscle nerve transmission.

3.Breathing problems: Certain breathing problems, such as obstructive sleep apnea or snoring, can cause shaking during sleep.

4.Stress and anxiety: Changes in emotional state, stress, and anxiety may also affect sleep, causing shaking or movements.

Usually under the condition of a mistress, this kind of sleep jerk is a normal physiological phenomenon and does not need to be too much to worry about. However, if you think that jitter is significantly affecting your sleep quality or is accompanied by other uncomfortable symptoms, it is advisable to consult a doctor for evaluation and further examination. Doctors can provide more accurate diagnoses and recommendations based on your specific situation.

The phenomenon of sudden shaking during sleep is very complicated. During sleep, brain cells used to be thought to be at rest. Updated research has found that the brain is also a cyclical activity during sleep, mainly the cyclical reversal of REM sleep and slow REM sleep.

In REM sleep, the human body is in a state of high metabolism, such as dreaming, physical activity, or turning over, indicating that the body is in a state of self-adjustment, so it is a physiological shaking, or this shaking will not cause discomfort to the human body.

In addition, it is a sleep disorder of REM sleep, which refers to the obvious shaking of the human body, and the patient's brain waves can be found to be similar to the discharge of Youhui epileptic waves through EEG monitoring. However, people with such abnormal discharges are more likely to suffer from Parkinson's disease, which is Alzheimer's disease, and other neurodegenerative diseases when they are older. Some of the shaking is that the patient does have epilepsy, and for the special type of epilepsy, it only occurs at night, only during the patient's sleep or deep sleep, and the lesion can be detected by monitoring the length of the sleep state.

During sleep, people are divided into light sleep and deep sleep. When the body goes into a deep sleep, the muscles gradually relax, and the heart rate and breathing also slow down, which is a more relaxed state.

However, before the body is completely relaxed, there is sometimes a phenomenon known as "hypnic jerk", which is commonly referred to as "shaking". This phenomenon occurs because the brain performs one last test on the body to ensure that it is safe to do so before going into deep sleep. If the brain detects that the body is not safe, it causes the muscles to contract briefly through nerve signals, causing the body to shake.

There is also an opinion that this phenomenon may be related to stress, fatigue, and other factors. When the body is in a state of tension or fatigue, the brain may be more prone to sending erratic signals, leading to the phenomenon of "shaking".

This sudden shaking is known as sleep myoclonus and is a common and common phenomenon, especially during the onset of sleep phase or during sleep. Here are a few reasons that can cause muscle twitching during sleep:

Sleep stage transition: Sleep is made up of several different phases, including the onset phase, light sleep, and deep sleep. As the body transitions from one stage to another, there may be a brief incongruity in the nervous system, causing the muscles to twitch.

Rapid eye movement sleep (REM): REM sleep is a stage in the sleep cycle that is associated with vivid dreams and rapid eye movements. During REM sleep, the muscles are usually in a state of relaxation to prevent the person from moving in the dream.

However, sometimes during REM sleep, the nervous system may trigger muscle twitching.

Stress and anxiety: Stress, anxiety and nervousness can lead to instability of the nervous system, which in turn can trigger muscle tics. This phenomenon is especially common before falling asleep, as people may be more likely to feel stress and anxiety before sleep.

Muscle fatigue or overexercise: Overtired muscles may experience twitching during sleep. This can be related to excessive exercise, prolonged physical exertion, or strenuous exercise.

Effects of Drugs or Substances: Certain medications, medications***, or substances such as drinking too much caffeine or alcohol can interfere with the normal functioning of the nervous system, causing sleep muscle twitches.

It is important to point out that sleep muscle tics are usually harmless and do not require special **. If tics are infrequent, do not interfere with sleep quality, and there are no other significant sleep problems, there is generally no cause for concern. Thank you.

Isn't this something you're used to, but most people probably don't have it, right?
