The world of adults is not easy. Even if you just want to sleep peacefully, sometimes it is a luxury. In addition to insomnia and dreaminess , many people also encounter various minor problems while sleeping - such as "body shaking violently"... What is going on?
Perhaps you have also had this experience: just when you were about to fall asleep, your body suddenly shook violently as if you were getting an electric shock, or your feet seemed to have stepped on the air, which startled you awake. This is the so-called sleep startle , a phenomenon also known as "hypnagogic jerks" or "hypnagogic myoclonus."
The American Sleep Association points out: About 70% of people will experience sleep startles at least once in their lives, 10% of them will experience it every day.
There are different opinions on the reasons. Some say it is because you are growing taller, some say it is because your brain is testing whether you are "dead", and some say it is a signal of sudden death...
In fact, it has little to do with any of these.
The brain has a tool machine for controlling arousal. When the machine is started, people will become sensitive and active. At the same time, the brain also has a machine that controls sleep. When it is activated, people will become sleepy.
Under normal circumstances, the two sets of machines will alternately operate in an orderly manner, but sometimes bugs will inevitably occur, causing the two sets of machines to "fight each other." At this time, sleep startle appeared. This is as normal as your hiccups or eyelid twitching, so there is no need to worry too much.
However, if sleep twitching occurs frequently (more than five times a night) , it may be that your body is sending you a warning:
① Excessive mental stress
Long-term excessive tension, overwork, high pressure, continuous tightness of the cranial nerves, control The two machines of wakefulness and sleep are easily out of balance.
② Brain damage
accompanied by headache, dizziness and other symptoms may be caused by damage to the cerebral cortex or hypothalamus, may be metabolic or storage diseases of brain cells, degenerative diseases of the brain, cerebral hypoxia sequelae, brain For sequelae of trauma, etc., a brain CT or MRI examination is required as soon as possible.
