Office workers spend most of their time sitting and working, so the chair is equivalent to their second bed. An ordinary office worker has to sit on a chair for at least 5-6 hours a day, and an IT practitioner can even sit on an office chair for 8 hours a day. More than 45% of office employees often experience back pain. Fatigue all over.
Inconsistent design of office chairs leads to knee strain, lumbar disc herniation and other diseases. In addition, cervical spondylosis, lumbar spondylopathy, and frozen shoulder are more common among office workers.
Sitting for a long time will reduce the contraction of the lower extremity muscles. When muscle activity decreases, the contractile force of blood vessels decreases. The blood flow rate will slow down or even become blocked, which can cause varicose veins in the lower extremities. Venous protrusions of varying degrees can be seen on the legs, curved like cockroaches; in severe cases, deep vein thrombosis of the lower limbs may be formed. So we must have a suitable chair to improve our status quo.
Therefore, a suitable chair can reduce physiological hazards. Finally, I advise everyone not to sit for a long time, and walk in the corridor in your free time! You can also do appropriate head-to-waist movements for a few minutes a day. I believe these problems will stay away from us.
