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

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
