Disadvantages: standing for a long time will make the calf thicker and prone to varicose veins. Teachers, surgeons, nurses, hairdressers, counter girls, chefs, restaurant waiters and other occupations that need to stand for a long time are all high-risk groups.

Varicose veins (commonly known as "hamstring muscle") are the most common diseases of venous system. The main reason for the formation is that blood accumulates in the lower limbs because of keeping the same posture for a long time, and the venous valve is destroyed over time, resulting in increased venous pressure and varicose veins. Varicose veins mostly occur in the lower limbs, and the skin of the legs is red or blue, like cobwebs, twisted blood vessels of earthworms, or hard nodules like tree tumors. The veins are abnormally enlarged, swollen and varicose.

Moreover, people with varicose veins have thick calves because they stand for a long time. Long-term injury to kidney, sedentary injury to spleen, long-term injury to liver. ....

Stand up. . Do more harm than good, it is better not to stand.
