Getting Started
Selecting a place to work
❖
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 readability 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
shines directly into 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.
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, short 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.
