Health concerns associated with computer use

Muscle soreness, eye fatigue, and other discomforts and injuries sometimes associated with computer use can result from performing any number of activities. Misuse of the same muscles during multiple activities can create a problem that might not otherwise exist. For example, if you engage in nonwork activities that involve repetitive stress on the wrist—such as bicycling—and also use your computer’s keyboard improperly, you may increase your likelihood of developing wrist problems. Preventing health problems requires careful attention to the way you use your body at all times.

The most common health effects associated with using a computer are musculoskeletal discomfort and eye fatigue. Any activity that involves sitting for long periods of time, including using a computer, can make your muscles sore and stiff.

To prevent discomfort and fatigue:

mArrange your work space so the furniture is properly adjusted for you and doesn’t contribute to an awkward, inappropriate working posture.

mTake frequent short breaks to give your muscles and eyes a chance to rest and refresh.
