summary

Sometimes, when we are sleeping, our legs or arms will shake suddenly. What's the matter? In fact, this kind of shaking is called physiological muscle jerk, which is a physiological phenomenon that many of us have experienced. Let's take a look at the following.

What reason is leg shake when female sleeps

First: muscle jerk is the rapid twitch of the muscle involuntarily, the speed is extremely fast, like an electric shock. Physiological muscle jerk is a normal physiological phenomenon. It is usually a sudden shaking of limbs when sleeping. It is an instinctive nerve contraction when people fall asleep. This is because the brain will also inhibit the activity of limbs muscles when sleeping, but the inhibition is very low, and the speed of blood circulation in the body is very slow. At this time, limbs muscles will not be "directed" by the brain temporarily ”There are some involuntary conditioned nerve movements.

Second: daytime pressure, excessive anxiety, extreme fatigue, or serious lack of sleep, can make people sleep early into the dream period, and the physical phenomenon of limbs suddenly shaking.

Third: sleeping on your back, lying on your stomach, sleeping with a quilt over your head, putting your hands on your chest, and covering the quilt too thick can increase the load on your heart, slow blood circulation and poor breathing, resulting in conditioned reflex of limbs not controlled by your brain.

matters needing attention

If the body is short of calcium and the calcium content in the blood is low, it can make the muscles and nerves over excited and cause the limbs to twitch occasionally.
