Frequent sudden shaking during sleep

If you often experience shaking while sleeping, you should pay attention to it. There are many reasons for this, including physiological reasons, such as fatigue during the day, drinking, emotional changes, etc., which may all cause this phenomenon. Of course, it is also related to brain disease. If there is a brain disease, this twitching and shaking phenomenon will also occur. The specific situation requires specific analysis.

Two hypotheses about hypnic twitches

The scientific experts from the well-known domestic science website Guokr.com also explained what "muscle twitch" is. It is a rapid, involuntary muscle twitch, similar to the feeling of being electrocuted. Although myoclonus is a physical disease that affects a person's normal life when the condition is more serious, physiological myoclonus (such as hiccups, sleep twitches, and muscle twitches caused by fatigue or tension) also often occur in normal people's daily lives. The reporter also saw on the Guokr website that although the phenomenon of sleep twitching was recorded as early as 1890, people still know very little about it. There are two popular hypotheses about its cause: The first hypothesis is that it is a special neural activity. People need to go through a series of switching from wakefulness to sleep. In this switching process, the reticular activating system plays an important role. Muscles also switch states when falling asleep. If the reticular activating system accidentally "fires" during the switching, it will stimulate the nerves and cause convulsions. Recent research results tend to support the second view that this is a glitch in the brain's work. Sleep twitches may originate from subcortical activity. When falling asleep, muscles throughout the body begin to relax. Due to the lack of a feedback signal, the brain mistakenly believes that this muscle relaxation is dangerous information that the body is falling, so it mobilizes the motor system to protect itself, resulting in muscle twitches.

Sleeping taboos

1. Avoid overusing your brain before going to bed. If you have the habit of working or studying at night, finish the more brain-intensive tasks in advance, and do something relaxing before going to bed to relax your brain, which will make it easier to fall asleep. Otherwise, the brain will be in an excited state, and it will be difficult to fall asleep even if you lie in bed. Over time, you will easily suffer from insomnia. 2. Avoid being emotionally excited before going to bed. People’s joy, anger, sorrow, and happiness can easily cause excitement or disorder of the nerve center, making it difficult to fall asleep and even causing insomnia. Therefore, before going to bed, try to avoid being too happy or too angry, or too worried or angry, and keep your emotions stable.
