Selecting a place to work

Adjust the back of your chair so that it supports the lower
curve of your spine. If necessary, use a cushion to provide
extra back support. Lower-back-support cushions are
available at many office supply stores.
Sit with your back straight so that your knees, hips, and
elbows form approximately 90-degree angles when you
work. Do not slump forward or lean back too far.
Lighting
Proper lighting can improve the visibility of the display and
reduce eyestrain.
Position the display panel or external monitor so that
sunlight or bright indoor lighting does not reflect off the
screen. Use tinted windows or shades to reduce glare.
Avoid placing your computer in front of a bright light that
could shine directly in your eyes.
If possible, use soft, indirect lighting in your computer
work area.
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.
