Ergonomics is the science of fitting workstations and equipment to individual human characteristics for safety, efficiency and comfort. Effective ergonomic design reduces injuries and increases productivity. To determine if a workstation fits properly, listen to your body and see a doctor if discomfort persists or worsens. Key factors in setting up a computer workstation include adjusting the chair, keyboard, monitor, and phone positioning as well as taking breaks and changing postures to prevent musculoskeletal disorders.
