Computers have become the essential component
in the modern world and health deconditioning occurs simultaneously with the
modernization. People in the software profession and students used to spend
most of the time in the computer and in the internet. Prolonged
postures, coupled with high levels of concentration and the occasional
frustration of things going less than perfectly, can lead to physical problems.
Some of the resulting
physical ailments are Carpal tunnel syndrome, Tennis elbow, Head ache, Computer
vision syndrome and Cumulative trauma disorder (CTD) or Repetitive strain
injury (RSI), Psychosomatic disorders. The symptoms of RSI are tightness,
discomfort, stiffness, burning in the hands, wrist, fingers, forearms and
elbows. Tingling, coldness and numbness of the hands with loss of strength and
lack of co-ordination occur. There is pain in the upper back, shoulders and
neck.

Ø Maintain sufficient interval between eye and the monitor.
Ø Maintain support at the low back.
Ø Keep hip and knee at right angle.
Ø 90-100o
Ø Keep your feet flat on the ground or use a foot rest.
Ø Position your keyboard at elbow level, with your upper arms relaxed
at your sides.
Ø While typing, use a light touch and keep your wrists straight.
Ø When you're not typing, relax your arms and hands.
Ø Take a short break every 15 to 20 minutes.
Ø Give adequate rest to the eyes by closing the eyes and blinking frequently.
Ø Type with your hands and wrists floating above the keyboard, so that
you can use your whole arm to reach for distant keys instead of stretching your
fingers.
