[0002] With the development of society, people have neglected their own physical health while pursuing economic benefits. More and more people have become sedentary people because they often sit for long periods of time at work. Some paraplegic patients are also forced to stay in bed or sit for long periods of time due to physical diseases. These people are prone to various diseases due to long periods of sitting. In addition, long periods of sitting will lead to slower blood circulation, which may cause myocardial atrophy and high blood pressure. At the same time, the body's immune cells are insufficient and immunity is reduced. Sitting for a long time will also lead to muscle relaxation, reduced elasticity, and lower limb edema.
