​computer use and health issues

​We have learned in previous classes about the benefits of using computers. We have come to know that computers are being used productively in many fields. Many office goers, university graduates, and school students use computers. But, not many are aware of health issues related to prolonged and incorrect use of computers. In this chapter, we will discuss some of those health issues:
A. Muscle and Joint Pain. People using computers for long hours often complain about muscle and joint pains. Muscles and joints can become stiff and painful due to either sitting in one place for a long duration or working on computer in awkward postures.
B. Back, Neck, and Shoulder Pain. Use of inappropriate chairs and tables while working on computer leads to sitting in awkward postures. That puts pressure on the back and neck areas, sometimes causing stiffness and swelling in these parts.
C. Arm, Wrist, and Finger Pain. Pain in the arm, wrist, and finger can be caused by working with bent wrists, repetitive use or lack of rest for the hands and forceful hand motions. Typing and clicking a mouse button may seem harmless but doing it again and again without breaks can eventually cause pain.

​D. Eye and Vision Problem
Eye problem is a common issue with computer users. Using computer for long duration can result in overworking of muscles in the eye that could lead to blurred vision, itchy eyes, and inability to see colour. Eye problem can lead to headache. It has also been noticed that being too close or too far to the monitor, bright light and reflections on computer screen can strain our eyes.
