Ergonomics is the discipline of arranging the work environment to fit the person. When properly applied in the work environment, ergonomics can reduce visual and musculoskeletal discomfort and fatigue. Repetitive motion injuries are caused by excessive and repeated physical stress on parts of the body and can result in conditions like carpal tunnel syndrome or repetitive strain injury. To help prevent such injuries, it is important to take regular breaks, adjust one's workstation properly, and avoid excessive tension in the body.
