This document discusses the health hazards of excessive computer use. It identifies six main health issues: 1) musculoskeletal problems like back pain from poor posture, 2) repetitive stress injuries from repetitive motions, 3) vision problems like dry eyes from long screen time, 4) headaches from muscle tension, 5) obesity from a sedentary lifestyle, and 6) stress disorders from work pressure and prolonged stress. To avoid these issues, it recommends taking breaks, stretching, maintaining proper posture, and limiting computer use especially for children.

2. HAZARDS OF USING COMPUTER
Computer has become integral part of the life of modern
man.Over use of it creates many problem of health
.These health hazards are grouped under six heads for
the sake of convenience as given below;
1)Musculoskeletal problems
2)Repetitive stress injury
3)Vision problem
4)Headache
5)Obesity
6)Stress Disorder

3. 1.Musculoskeletal problems:Muscle sorenesss
and muscle fatigue are the most common
complaints of regular computer users.Back pain
,chest pain ,pain or numbness in arms ,shoulder
and feet top the list.These types of problems
mainly occur because the user’s while using
the computer is not correct.Either he is sitting
on an uncomfortable chair or his workstation is
not supportive of correct posture .
To avoid this,the user should adjust his chair and
desk such that the screen is either at his eye level
or lower .He must sit with his back straight and
legs perpendicular to the floor with feet resting flat
on the floor .His elbows should rest at the sides .It
is good to take short breaks from work and stretch
a bit or go for a short walk.
2, Repetitive Stress injury :Pain in the neck
,shoulder ,or anywhere from the shoulder to

4. fingers may indicate repetitive stess injury.When
the users uses his muscle in an awakward
position,he may experience stiffness ,pain or
swelling in that area.For example,twisting the
wrist to use the mouse or specific typing
technique that causes stretching of fingers or
pressure on the wrist can turn really painfull.one
of the disorders that affect the fingers and wrist
is carpal tunnel syndrome.
The following method of moving the mouse and
typing is the solution to this problem:
Adjust the mouse beside the Keyboard.Move the
entire arm while moving the mouse .Don’t just
move the by fixing it at one position .Typing should
be gentile .Do not fix the wrists in a certain
position while typing .It is good to relax the arms
or using the mouse.
2.Vision problem:The most common health
complaints of those who regularly use
computers for long duration ,are about eye and
vision problem.Bright light and bad glare or

5. flicking image can cause dry eyes.computer
vision syndrome is another problem that the
user may suffer from.
3.Headache:Because of increased muscle tension
or pain in theneck at the base of the
skill,headache is the common problem with
computer use.many a times,prolonged use can
effect eye power which needs vision
correction.Get the eye power tested if
headache is a common problem with computer
use.
Keep the neck straight when infrond of the
computer.constantly looking down or stretching
the neck sideways can also cause pain.Take breaks
in between and circle the neck a bit to realease the
strain.
5 .Obesity:studies have shown that prolonged use
of computers especially in children,is the major
contributing factor of sedentary lifestyle and
childhood obesity.
Remedial step to be taken :

6. Set limits for children if they insist to
playingcomputer game non stop.
Encourage children to play out doorgames
or to take up a hobby .Involve them in extra-

6.Stress disorder:Technology has a huge
impact on our behaviour and
emotions.Prolonged computer use along

susceptible they become to other health
issusesmentioned above .It can also lead to

7. loss of concentration ,dizzinessand
weariness.
Be proactiveand take necessary measures to
beat stress before it affects health .Pratice
yoga is good to avoid stress disorder
