The noise about hazards for computer users started in the 80’s and culminated in the 1992 Health and Safety DSE (Display Screen Equipment) regulations. Then came Carpal-Tunnel Syndrome followed by ergonomics.
The publicity has subsided, since we all know the computer is not going to kill us; but in the last two decades, we have learned a lot potential health risks related to Central Processing Unit of computers, monitors and laser printers. Today we have also learned different ways to avoid being at risk. Let’s look at some of the most common medical problems.
Eye problems are probably the major problems experienced by computer users. These include fatigue, blurred vision and dry eyes. These symptoms are also aggravated by external factors, such as poor lighting, improperly designed work-stations and viewing the screen up too close. Other problems are stress, depression and electromagnetic radiation hazards. Do not forget that it is better to stay away from the back of monitors, where the electromagnetic field is stronger and against which walls did not give any protection. The monitor screen surface should be approximately 18-24 inches away from upper body. It is good to have a suitable monitor screen without any wave.
Some people are highly sensitive to the gasses given off by computers. One source of this gas is the plastic components. As we know that most plastics are unstable and break down naturally over time, particularly when exposed to ultraviolet light and sunlight. And when the equipment is new, the out-gassing is much greater and noticeable even to people who are not particularly sensitive. It is like new cars. We are familiar with what a new car smells like. That smell is mostly out-gassing from the vinyl, plastic carpet and hard plastic interiors, as well as the wiring. And a new computer has a similar smell.
Organise your computer-work properly. Look away from the screen periodically. Sit up straight and if possible chairs should be on wheels, have backrest tilt adjustment, and have arms. And of course, do not forget to blink, your eyes need the moisture.
