The repetitive motions of using a computer are often associated with a condition called carpal tunnel syndrome. According to the U.S. National Library of Medicine, typing is the most common cause. The syndrome develops due to pressure on the median nerve. Symptoms include numbness, tingling, weakness, or pain in the wrist, hand, fingers, or lower arm.
To prevent carpal tunnel syndrome, set up your work area so that you can type and use your computer without strain. A split keyboard, keyboard drawer, and/or adjustable-height chair can all help you keep your wrists in a neutral position. Take frequent breaks and wear a wrist brace if you experience symptoms. See a health care provider for treatment if they persist, to prevent permanent nerve damage.
