Working Practices
This section gives
advice on how you can
work comfortably and reduce
fatigue.
Rest
Take regular breaks. Vary your posture, stand up and stretch occasionally as
prolonged use of computer workstations can be tiring.
Back
Adjust the height and angle of the chairback to support your lower back. Sit
well back in your chair.
Hands
Adjust the seat height so that your forearms are approximately horizontal and
your wrists are straight when using the keyboard. Your upper arms should be
relaxed with your elbows near your body.
Use a light touch on the keyboard, keeping your hands and fingers relaxed.
Allow a space in front of the keyboard to rest your wrists when not typing.
Consider using a wristpad.
Eyesight
Working with monitors, in common with any prolonged close work, can be
visually demanding. Look away from the screen periodically and have your
eyesight checked regularly.
Screen settings
Set the screen brightness and contrast to a comfortable level. You may have
to adjust this as the lighting changes during the day. Many application
programs let you select color combinations which can help you to view in
comfort. See the User controls section starting on page 14 for more
information.
