Regular computer users run the risk of several health problems. Most computer-related jobs require people to sit in front of the computer for longer periods.
The term "ergonomics" is derived from two Greek words: "ergon", which means work and "nomoi", which means natural laws. According to the National Pain Foundation, ergonomics is "the science of designing the job to fit the worker, rather than physically forcing the worker’s body to fit the job." Workers who do more of "static work" or maintain certain postures for a long time develop something called repetitive stress injuries (RSIs) over a period of time. Ergonomists study such problems and define postures that minimize unnecessary static work, reduce the harmful forces acting on the body, and in the end, considerably minimize the risk of injury.
1. Stretch once an hour
Do not sit in a posture for more than an hour. Lean forward, cross your arms in front of you, hold your knees, and push your knees apart, keeping your hands on them. You’ll feel this stretch across your shoulder blades. Stretch your fingers, arms, hands, and torso at regular intervals.
2. Exercise throughout the day
Make sure you move your hands, legs, back, and neck every 10 minutes throughout the day. Get up and take short walks from your workstation periodically.
3. Maintain a good working posture
Following are important considerations when attempting to maintain neutral body postures while working at the computer workstation:
• Hands, wrists and forearms are straight, in-line and roughly parallel to the floor.
• Head is level or bent slightly forward, forward facing, and balanced. Generally it is in-line with the torso.
• Shoulders are relaxed and upper arms hang normally at the side of the body.
• Elbows stay in close to the body and are bent between 90 and 120 degrees.
• Feet are fully supported by floor or footrest.
• Back is fully supported with appropriate lumbar support when sitting vertical or leaning back slightly.
• Thighs and hips are supported by a well-padded seat and generally parallel to the floor.
• Knees are about the same height as the hips with the feet slightly forward.
