Arms And Wrists; Work Habits - Toshiba Satellite Pro 4600 Series User Manual

Sit with your back straight so that your knees, hips, and
elbows form approximately 90-degree angles when you work.
Don't 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.

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
work 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.
