If you stand for prolonged period, muscles get tired and their tendons and ligaments can be damaged, causing soft tissue injuries. Standing still also reduces blood flow to muscles and stops the “muscle pump” (regular muscle movements) that returns blood from the feet and legs to the heart. It leads to pooling of blood to legs and increase risk of cardiovascular disease. Thus intermittent sitting, stretching and use of right shoes/ insoles is recommended.
The prolonged standing at industrial workplace include musculoskeletal disorders (discomfort in various body parts and joint pains); chronic venous insufficiency (varicose leg veins); preterm birth and spontaneous abortion (during pregnant condition) and carotid atherosclerosis (lead to heart attack) while minimizing health impact. The physical impact include diminished function of calf muscles, muscle fatigue, pain in lower back (especially more twisting of upper body) and eventually performance decrement. Standing puts more strain on body than sitting.
