What is the reason for shivering after falling asleep

summary

Often when we sleep, we suddenly feel like our feet are empty, and then our whole body shakes. Tell you the truth - this is called muscle jerk, which often occurs during sleep. The respiratory rate drops too much during sleep. The brain thinks that the body is dying, so it will send a pulse to wake up the body. I'll tell you why I shiver after I fall asleep.

What is the reason for shivering after falling asleep

First: physiological muscle jerk this type of muscle jerk is normal physiological performance, not caused by disease, such as hiccups, muscle jerk in sleep, muscle jerk when fatigue or tension. Sleep twitch, sometimes called sleep fright, is a scientific term for a sudden shake when you sleep. This kind of unconscious muscle twitch will appear in your arms, legs and even the whole body when you go to sleep. Most people have this experience: about 70% of them have shaken in their sleep.

Second, the occasional "muscle jerk" is a normal physiological phenomenon. Ou Hongxia, chief physician of the medical psychology department of Nanjing Brain Hospital, said that there is no such saying of "muscle jerk" professionally. She thought it might be a popular expression of muscle jerk among the people. "It's normal to have a jerk when you sleep. Everyone will have it." Ou Hongxia said that this kind of occasional twitch or shaking is because people are in the "rapid eye movement period" of sleep, which is a normal physiological phenomenon that occurs when they dream.

Third: why? There are two main theories about sleep twitch, which are based on neuroscience and evolution. 1. The most common explanation is that when you fall asleep, there are two different systems in the brain that are fighting each other. When you feel a little sleepy, system 1 will usually transfer control to system 2 VLPO. At this time, the sleep twitches will stop, so these sleep twitches are considered to be the result of the sleep wake struggle in the body every time you try to sleep. 2. Another view is that after sleeping, the body muscles should be relaxed, but some people's muscles are not completely relaxed after sleeping due to sleeping posture, daytime fatigue, excitement, irritability and other reasons, and sleep enters the "rapid eye movement period". When dreaming, especially when dreams are too vivid and stimulate the brain central nervous system to send out signals, they will produce small movements and dream It's about the situation.

matters needing attention

1. Cut down on coffee. 2. Finish the work in the daytime. 3. Controlling stress levels and sleep patterns may reduce sleep twitch.
