Applying ergonomics can help prevent repetitive motion injuries such as carpal tunnel syndrome, particularly if you are constantly working at a computer. Use a headset for lengthy or frequent telephone work. A footrest should be used if, after adjusting the height of the chair, feet do not rest flat on the floor. When performing daily tasks, alternate between sitting and standing or take small walking breaks throughout the day. Position the monitor directly in front of the user to avoid excessive twisting of the neck. When typing, press the keys gently; do not bang them or hold them down for long periods. Keep your shoulders, arms, hands, and fingers relaxed.
