Arms and wrists
Avoid bending, arching, or twisting your wrists. Keep
them in a relaxed, neutral position while typing.
Exercise your hands, wrists, and arms to improve
circulation.
WARNING: Using the computer keyboard incorrectly may
result in discomfort and possible injury. If your hands,
wrists, and/or arms bother you while typing, stop using the
computer and rest. If the discomfort persists, consult a
physician.
Work habits
The key to avoiding discomfort or injury from strain is to vary
your activities. If possible, schedule a variety of tasks into
your working day. Finding ways to break up the routine can
reduce stress and improve your efficiency.
Take frequent breaks to change position, stretch your
muscles, and relieve your eyes. A break of two or three
minutes every half hour is more effective than a long
break after several hours.
Avoid performing repetitive activities for long periods.
Intersperse such activities with other tasks.
Focusing your eyes on your computer screen for long
periods can cause eyestrain. Look away from the
computer frequently and focus your eyes on a distant
object for at least 30 seconds.
