COMFORTABLE

USE

Computer users may complain of eyestrain and headaches after prolonged use. Users 
are also at risk of physical injury after long hours of working in front of a computer. Long 
work periods, bad posture, poor work habits, stress, inadequate working conditions, 
personal health and other factors greatly increase the risk of physical injury.
Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis, tenosynovitis 
or other musculoskeletal disorders. The following symptoms may appear in the hands, 
wrists, arms, shoulders, neck or back:

- Numbness, or a burning or tingling sensation.
- Aching, soreness or tenderness.
- Pain, swelling or throbbing.
- Stiffness or tightness.
- Coldness or weakness.

If you have these symptoms, or any other recurring or persistent discomfort and/or pain 
related to computer use, consult a physician immediately and inform your company's 
health and safety department.
The following section provides tips for more comfortable computer use.

Finding your comfort zone

Find your comfort zone by adjusting the viewing angle of the monitor, using a footrest, or 
raising your sitting height to achieve maximum comfort. Observe the following tips:

- Refrain from staying too long in one fixed posture.
- Avoid slouching forward and/or leaning backward.
- Stand up and walk around regularly to remove the strain on your leg muscles.
- Take short rests to relax your neck and shoulders.
- Avoid tensing your muscles or shrugging your shoulders.
- Install the external display, keyboard and mouse properly and within comfortable 

reach.
