Keep your hands and fingers relaxed when you are typing and
try not to press the keys too hard; using too much force creates
tension in your hands. Remove your hands from the keyboard
when you are not using it and take frequent breaks to stretch
your hands and fingers.
When using a mouse, keep your wrist and fingers relaxed. Let
go of the mouse frequently and stretch or relax your hand.
Leave enough space on your work surface so you can freely
move the mouse.
Maintaining Good Posture and Work
Habits
Here are suggestions to help you stay fit while
using your computer. If you form good work
habits, you shouldn’t have to spend too much time thinking
about it!
Work in a relaxed, natural, upright position and let the
chair support you. Your back and neck should be straight
with your shoulders down and relaxed. Keep the elbows
and hips bent at about a 90 degree angle and your forearms
and thighs parallel to the floor.
Try to keep your arms in an easy, natural position with
your elbows near your body and level with or slightly
lower than the keyboard. Your wrists should be straight,
not bent, and your hands should rest lightly on the keys or
the mouse.
Rest your eyes occasionally by closing them or focusing on
a fixed spot in the distance.
Change your sitting position frequently throughout the day
to avoid muscle fatigue. Take periodic breaks; stand up,
stretch, and move around.
