Proper Seating Posture During Computer Use
The proper seating posture during computer use is provided here.
Maintaining proper posture during computer use enhances performance
and prevents physical bodily harm.
Seating Posture
- Position the chair so that the eyes are slightly higher than the display
panel.
- Straighten the neck and back.
- Place the legs naturally.
- If necessary, use a cushion to provide extra back support.
- Avoid working postures that require twisting the body or neck.
Lighting
- Soft, indirect lighting is recommended.
- Position the display panel so that external light does not reflect off the
screen. Use curtains, if necessary.
Work Habits
- Take periodic breaks and stretch out stiff muscles regularly.
- Look outside the window or at distant objects frequently to relieve strain
on the eyes.
If necessary, use a footrest to raise the level of your knees
and ease the pressure on the thighs.
