Watch your posture

Ergonomics experts recommend that you maintain a relaxed but upright posture,without excessive bowing of your back,and without leaning your neck forward unnaturally to view your monitor.Your shoulders should be relaxed,and your arms forearms should extend straight out from your elbow,forming a 90 degree angle at the elbow.The same goes for your knees.Good posture can go some way toward preventing musculoskeletal disorders that arise from extended sitting at the computer.
