To your health
Can all this computing be good for you? Are there any unhealthy side effects? The computer seems harmless enough. How bad can it be, sitting in a padded chair in a climate-controlled office?
Health questions have been raised by the people who sit all day in front of the video display terminals (VDTs) of their computers. Are computer users getting bad radiation? What about eyestrain? And what about the age-old back problem, updated with new concerns about workers who hold their hands over a keyboard? What about repetitive-action injury also known as carpal tunnel syndrome?
Unions and legislators in many communities continue to push for laws limiting exposure to video screens. Many manufacturers now offer screens with built-in protection.
Meanwhile, there are a number of things workers can do to take care of themselves. A good place to begin is with an ergonomically designed workstation. Ergonomics is the study of human factors related to computers. A properly designed workstation takes a varie¬ty of factors into account, such as the distance from the eyes to the screen and the angle of the arms and wrists.
Experts recommend these steps as coping mechanisms:
• Turn the screen away from the window to reduce glare, and cover your screen with a glare deflector.
• Turn off overhead lights; illuminate your work area with a lamp.
• Put your monitor on a tilt-and-swivel base.
• Get a pneumatically adjustable chair. Position the seat back so your lower back is supported.
• Place the keyboard low enough to avoid arm and wrist fatigue. Do not bend your wrists when you type. Use an inexpensive, raised wrist rest. Do not rest your wrists on a sharp edge.
• Sit with your feet firmly on the floor.
• Exercise at your desk occasionally rotating your wrist, rolling your shoulders, and stretching. Better yet, get up and walk around at regular intervals.
