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:
m Arrange your work space so the furniture is properly adjusted
for you and doesn’t contribute to an awkward, inappropriate
working posture.
m Take frequent short breaks to give your muscles and eyes a
chance to rest and refresh.
