As with any activity that involves sitting for long periods of time, using
a computer can make your muscles sore and stiff. To minimise these effects, set
up your work environment carefully and take frequent breaks to rest tired muscles.
Another type of musculoskeletal concern is repetitive stress injuries (RSIs),
also known as cumulative trauma disorders (CTDs) [or Occupational Overuse Syndrome
(OOS)]. These problems can occur when a certain muscle or tendon is repeatedly
overused and forced into an unnatural position.
One RSI discussed more often today, is a wrist problem called carpal tunnel
syndrome, which may be aggravated by improper use of computer keyboards. This
nerve disorder results from excessive pressure on the median nerve as it passes
through the wrist to the hand.
No one, of course, can guarantee that you won't have problems even when you
follow the most expert advice on using computer equipment. You should always check
with a qualified health specialist if muscle, joint, or eye problems occur .
Eye fatigue can occur whenever the eyes are focused on a nearby object for
a long time. This problem occurs because the eye muscles must work harder to view
an object that's closer than 6 metres. Improper lighting can hasten the development
of this problem Although eye fatigue is annoying, there's no evidence that it
causes permanent damage.
Whenever you're engaged in an activity that involves close-up work--such as
reading a magazine, doing craft work, [draughting on a drawing board], or using
a computer--be sure to have sufficient glare-free lighting, give your eyes frequent
rest breaks by looking up and focusing on distant objects, and remember to have
your eyes examined regularly .
Recently, questions about the possible health effects of prolonged exposure
to extremely low frequency (ELF) and very low frequency (VLF) electromagnetic
fields have been raised. The issue encompasses not video display terminals (computer
displays), but also other electromagnetic sources such as electrical wiring, televisions
and household appliances.
