Ergonomics and Health

Along with the benefits of computer technology comes the potential for unwelcome side effects. For people who work long hours with computers, the side effects include risks to health and safety due to radiation emissions, repetitive strain injuries, or other computer-related health problems. Inconclusive evidence suggests that low-level radiation emitted by video display units (VDUs) and other equipment might cause health problems, including miscarriages in pregnant women and leukemia.The scientific jury is still out, but the mixed research results so far have led many computer users and manufacturers to err on the side of caution.

More concrete evidence relates keyboarding to occurrences of repetitive strain injuries such as carpal tunnel syndrome a painful affliction of the wrist and hand that results from repeating the same movements over long periods. Prolonged computer use also increases the likelihood of headaches, eye strain and fatigue.

Ergonomics (sometimes called human engineering) is the science of designing work environments that allow people and things to interact efficiently and safely.

To sit comfortably and healthily at the computer, the following points should be addressed:
 
 

Screen 3 to 4 times brighter than room	Screen arm's length away and 15 to 30 degrees below line of sight	Adjustable monitor	Desktop 29 inches from floor	Adjustable chair
Fingers no higher than 10 degrees above elbow	Forearms horizontal	Wrist pad	Lower back support	Feet flat on floor or on foot rest
