How to Use Computers without Feeling Body Fatigue
Many people are not aware of the concept “Ergonomics” as a science, but it really is. Ergonomics is an applied science concerned with designing and arranging things people use so that the people and things interact most efficiently and safely. If we apply the term to the computer field, we are going to see ergonomics has the purpose of re-imagining the design of technology products to optimize them for human use and to teach us how to avoid computer fatigue.
When we think about ergonomic laptops/desktops with the above information in mind, we talk about computers that are functional, suitable, efficient and feasible not only “under the hood” but also on the exterior. Who wouldn’t like a laptop with the perfect screen size, laptop legs, long-lasting battery, light weight and a comfortable keyboard. All these features together with a good design make a laptop/desktop ergonomic and more optimized for human use.
Another concept of computer ergonomics we should not ignore is related to the risk of stress, physical injury and computer eye strain. Computer ergonomics addresses ways to optimize your computer workstation to reduce the specific risks of computer vision syndrome (CVS), neck and back pain, carpal tunnel syndrome and other disorders affecting the muscles, spine and joints.(Dr. Heiting). If we understand this concept and try to follow the recommendations written below then we’re going to learn how to avoid computer fatigue.
The U.S. Department of Labor’s Occupational Safety & Health Administration (OSHA) has recommended the following tips to reduce the effects of those health disorders:
- Sit so your head and neck are upright and in-line with your torso, not bent down or tilted back.
- Face your computer screen directly. Avoid viewing your screen with your head turned or your back twisted.
- Keep your elbows comfortably close to your body.
- Use a chair that provides support for your lower back and has a cushioned seat with a contoured front edge.
- Keep your mouse close to your keyboard so you don’t have to reach for it.
- Position your computer display so the top of the screen is at or slightly below eye level. This will allow you to view the screen without bending your neck.
- Adjust the position of your display to prevent reflections of overhead and outdoor lighting appearing on your screen.
- Put your monitor close enough to your eyes so you can comfortably read text on the screen without leaning forward.
- When working with print documents, use a document holder that positions them at the same height and distance as your computer screen.
- Use a hands-free headset when talking on the phone while working at your computer.
Also, adjust the height of your chair and desk so that:
- Your upper arms are perpendicular to the floor, not stretched forward or angled backward
- Your forearms, wrists and hands form a 90-degree angle with your upper arms
- Your thighs are parallel to the floor and your lower legs are perpendicular to the floor
- Your wrists and palms are not resting on sharp edges
