Health-related information about computer use
Muscle soreness, eye fatigue, and other discomforts and injuries sometimes associated with using
computers can occur from performing any number of activities. In fact, 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.
Some individuals are at greater risk of developing these problems because of their health, physiology,
lifestyle, and general exposure to stress. Work organization and conditions, such as workstation setup
and lighting, also play a part in your overall health and comfort. Preventing health problems is a
multifaceted task that requires careful attention to the way you use your body every hour of every day.
