Adjusting your Workstation Helps Keep You Focused and
Alert at Work and Pain Free:
--Chair Adjustment (Preventing Posture Discomfort):
-
Adjust the height
of your chair so as to leave about 5cm of space between your thighs and the
bottom of your work surface.
-
Check to see
whether your feet lie flat on the floor.
If not, use a footrest.
-
Your backrest
angle should be between 95 and 100 degrees relative to the seat of the chair.
-
Adjust your
backrest height so that the lower third of the backrest fits into the arch of
your back.
-
The edge of the
chair should be about 5cm away from the back of your knees.
-
Knee angle should
be between 90 and 100 degrees.
-
Adjust the
armrests so that elbow angle is between 90 and 100 degrees. When resting your forearms on the armrests,
you should feel that your shoulders are relaxed.
--Monitor Adjustment (Preventing Eye Strain):
-
Your eyes should
rest at the top of the monitor or up to 10cm below eye level.
-
Distance between
your eyes and the monitor should be between 55 and 70 cm according to personal
preference.
-
Monitor should
preferably be tilted 5 degrees relative to vertical.
-
Adjust monitor
lighting and brightness to optimum setting.
-
Periodically
clean your monitor to remove dust caused by static electricity.
--Keyboard and Mouse Adjustment (Prevents Wrist Pain):
-
While using the
keyboard, bend all of your fingers slightly and try to avoid excessive strain
on any finger. Tap the keys lightly.
-
Do not rest your
wrists on a pad or any other surface; your fingers should float above the
keyboard.
-
Keep wrists
straight, both horizontally and vertically.
-
Keep your upper
arms perpendicular to your body and close to your sides.
-
Keyboard should
be parallel to the desktop. When typing
for long hours, keyboard should be at an angle of -5 degrees to the surface of the
table.
-
Rest the palm of
your hand on the mouse and click on it lightly.
