Shaking your legs properly can promote venous blood flow, accelerate blood return and relieve the feeling of pain and fatigue. In addition, shaking legs can also burn leg fat, which has a slimming effect.
For the elderly, sitting for a long time, such as playing chess and mahjong, may also cause deep venous thrombosis of lower limbs. When suddenly standing up, the thrombus may fall off, return to the heart with the vein, and then reach the lungs, causing fatal "pulmonary embolism." Therefore, shaking your legs often has a good effect on preventing embolism.
Extended data:
From a neurological point of view, shaking your legs is not a disease, but more of a behavior habit, similar to turning a pen and snapping your fingers. Many people will make all kinds of small moves to relieve their emotions when they are anxious and nervous, but this is not a healthy way to relieve stress. Once they get into the habit, it's hard to give it up.
In social situations, habitual leg shaking is very unpopular. Generally speaking, it is subconscious to like to shake your legs, which is often formed as a child. Some people rely on small movements such as shaking their legs to relieve anxiety, and as a result, they often become double anxiety without doing small movements.
