Ergonomics in the Workplace

For most professionals, sitting in front of a computer all day, every day, five days a week, is not uncommon. However, studies show that sitting for long periods of time in the same position is not good for the human body. People can develop muscle discomfort, fatigue, and eye strain from simply sitting too long. People in the workplace looking to prevent or ease these symptoms often seek ergonomic solutions.
Ergonomics is a science applied to the design and arrangement of equipment and furniture used in the workplace. One objective of the design and function of things is to make them healthy and safe for people to use. Using ergonomic principles, engineers have designed specialized desks, chairs, and computer stands to use in the workplace.
More and more, people are opting for these new desks, sometimes referred to as "sit-to-stand workstations."These special desks can be raised and lowered to fit any different position or posture. Workers can easily move them up and down to vary their posture. In fact, many people prefer to stand in front of a desk the entire day. Ergonomic principles can even be applied to people who prefer to sit. In addition to resting the feet flatly on the floor or on a footrest, an ergonomic supportive chair can help maintain proper posture. These special chairs can help prevent serious back problems and overall discomfort in the body.
The correct placement of the computer monitor is another important ergonomic principle. The computer monitor should be placed straight ahead so that the neck is not strained from looking too far up or down. Straining can cause soreness in the shoulders and affect back muscles and the spine. The height of the monitor should be just slightly below eye height and just a little more than an arm's length away. Computer screens should also be dimmed or slightly tilted so that the glare does not irritate the eyes.
These are just a few of the principals that apply to the study of ergonomics in the workplace. There are many more that can help increase productivity and decrease health risks. One might say that employers have an obligation to ensure that workstations are providing employees with the ability to move around and maintain proper posture. Employees who are more healthy and more at ease tend to feel more invigorated and take less sick days. In the long run, they become more valuable to the company.
