Does the use of sit-stand desks help improve blood flow?

Yes, using a sit-stand desk can help improve blood flow. Here are the specific reasons:
Reduce venous compression: Prolonged sitting can put pressure on the veins in the legs, which may restrict blood flow and increase the risk of thrombosis. Standing can alleviate this pressure and promote smoother blood flow back to the heart.
Promote circulation: Standing and moving help activate leg muscles and promote venous blood circulation. The contraction and relaxation of leg muscles can help push blood back through veins, reducing blood retention in the lower limbs.
Reduce swelling: Sitting for a long time may cause swelling in the legs and feet, as blood and fluids can accumulate in the lower limbs. By standing and walking regularly, this swelling can be reduced and lower limb health can be maintained.
Preventing varicose veins: Prolonged sitting is a risk factor for varicose veins. Standing and moving can reduce the pressure on veins and help prevent the occurrence of varicose veins.
Increasing oxygen supply: Improved blood circulation can increase oxygen and nutrient supply to various parts of the body, improving overall health and work efficiency.
Improving energy levels: Better blood flow can help reduce fatigue, maintain high energy levels and alertness, and enhance work efficiency.
