Proper posture when using your Desktop PC
When using your Desktop PC, maintaining the proper posture is necessary to prevent strain
to your wrists, hands, and other joints or muscles. This section provides you with tips on
avoiding physical discomfort and possible injury while using and fully enjoying your Desktop
PC.
To maintain the proper posture:
•
Position your computer chair to ensure that your elbows are at or slightly above the
keyboard to get a comfortable typing position.
•
Adjust the height of your chair to make sure that your knees are slightly higher than
your hips to relax the backs of your thighs. If necessary, use a footrest to raise the level
of your knees.
•
Adjust the back of your chair so that the base of your spine is firmly supported and
angled slightly backward.
•
Sit upright with your knees, elbows, and hips at an approximately 90º angle when you
are in front of your PC.
•
Place the monitor directly in front of you, and adjust the top of the monitor screen within
your eye level so that your eyes look slightly downward.
•
Keep the mouse close to the keyboard, and if necessary, use a wrist rest for support to
reduce the pressure on your wrists while typing.
•
Use your Desktop PC in a comfortably-lit area, and keep it away from sources of glare
such as windows and direct sunlight.
•
Take regular mini-breaks from using your Desktop PC.
