Like to shake your legs is a subconscious performance, which can promote blood circulation of lower limbs and maintain and enhance the vitality of muscle joints. The shaking action can not only stretch muscles, but also promote the blood return of lower limbs and prevent the formation of thrombosis and varicose veins in limbs.
It can be simply understood as the conditioned reflex of the human body.
It seems more reasonable to use "balance of forces" to explain it. First of all, normally, when people sit, their feet are flat on the ground. The action points used to support the balance of lower limbs are mainly concentrated in the heel and forefoot (the arch of the foot is not stressed). This relatively stable stress structure is broken when the heel is lifted and only the toe touches the ground. At this time, your lower limbs are mainly subjected to two forces. One is gravity, which forces your heel to fall without external force. Because it is difficult to form a stable supporting structure only by toes. Another force is your subjective force to lift your heel up through muscle contraction. Only when these two forces are the same, your legs will not tremble up and down. But after all, it is a person, not a machine. It is difficult to control the upward lifting force relatively stably. (Muscle fatigue, conscious or unconscious lifting, etc. ) So there are two trends. When you subjectively want to keep your legs in the same position, naturally lift and relax. The jitter generated.
Question 2: Why do many people like to shake their legs, especially men? Many people have the habit of shaking their legs when answering questions with shells. There are various sayings about shaking your legs. Let's explain them one by one. There is a disease in medicine called "restless leg syndrome", the main symptom is uncontrollable leg shaking, similar to our daily leg shaking. It has been rumored that * * * can relieve restless leg syndrome. This rumor has been reported in the article "Can * * * alleviate restless leg syndrome? "It was smashed. However, there is an essential difference between daily leg shaking and this disease. Restless leg syndrome is a nervous system disease, which is mainly related to abnormal dopamine metabolism and iron deficiency, and has certain genetic factors. However, most of the shaking of legs in our daily life does not belong to the category of disease, but is just a habitual action. Distinguishing whether leg shaking is "disease" or "non-disease" mainly depends on the following points: patients with restless legs syndrome can't control their leg shaking behavior, leg shaking is accompanied by severe pain, burning pain and other discomfort, and leg spasms often occur, which mostly occurs at night. If your leg tremors meet the above requirements, you'd better consult a doctor. There is a saying that modern people often sit for a long time because of work, which easily leads to "poor blood flow" and "weakness of lower limbs". And shaking your legs can just alleviate these conditions, which is a good exercise. Sitting for a long time can really lead to leg numbness, mainly because the lower limbs keep a posture for a long time, which is easy to affect the smooth blood circulation and may also oppress the sciatic nerve, both of which will have adverse effects on health. In this sense, shaking the legs can make the muscles of the lower limbs slightly move, which can avoid the phenomenon of leg numbness to some extent. However, the best way to avoid the harm caused by sedentary is to stand up and exercise, which is much healthier and more effective than shaking your legs. Some people say that shaking his legs can relieve tension and anxiety; I often shake my feet unconsciously when I am bored and upset. At this level, shaking legs is similar to some habitual actions in our lives, such as turning pens and snapping fingers. These habits have a common feature: they are easy to form psychological dependence. Once these habits are formed, it is difficult to get rid of them. It is better to say that if you don't shake your legs, your anxiety will double. Therefore, it is not worth promoting to relieve anxiety by shaking your legs. If shaking your legs becomes a bad habit that you can't quit, it will increase your psychological burden. From the above, it can be concluded that shaking legs is not a disease in most cases, and there is no particularly great adverse effect. But it will not only form psychological dependence, but more importantly, in social culture, shaking your legs is a very indecent behavior, which will cause dissatisfaction among people next to you. Some people even think that the opposite sex is a sexual hint ... In view of this, I suggest you try to quit.
