Tips and information for 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
