Developing Good Work Habits
Developing good work habits is important if you need to work in front of the computer for long periods
of time. Improper work habits can result in discomfort or serious injury from repetitive strain to your
hands, wrists or other joints. The following are some tips to reduce the strain:
• Adjust the height of the chair and/or desk so that the keyboard is at or slightly
below the level of your elbow. Keep your forearms, wrists, and hands in a relaxed
position.
• Your knees should be slightly higher than your hips. Place your feet flat on the
floor or on a footrest if necessary.
• Use a chair with a back and adjust it to support your lower back comfortably.
• Sit straight so that your knees, hips and elbows form approximately 90-degree
angles when you are working.
• Take periodic breaks if you are using the computer for long periods of time.
Remember to:
•
Alter your posture frequently.
• Stretch and exercise your body several times a day.
• Take periodic breaks when you work at the computer for long periods of time. Fre-
quent and short breaks are better than fewer and longer breaks.
