Explain 3 health effects due to prolonged use of computer and how to overcome each of them.
Answers
Answer:
The computer is a vital tool in many different jobs and activities, for adults and children. But long periods of using a computer can increase your chance of developing an injury. Inappropriate computer use can cause muscle and joint pain, overuse injuries of the shoulder, arm, wrist or hand, and eyestrain.
Children can experience particular physical and psychological problems if they play computer games too much. You can reduce or avoid these risks with the correct furniture, better posture and good habits, such as taking rest breaks and restricting time spent playing computer games.
Posture-related injuries from computer use
Back and neck pain, headaches, and shoulder and arm pain are common computer-related injuries. Such muscle and joint problems can be caused or made worse by poor workstation (desk) design, bad posture and sitting for long periods of time.
Although sitting requires less muscular effort than standing, it still causes physical fatigue (tiredness) and you need to hold parts of your body steady for long periods of time. This reduces circulation of blood to your muscles, bones, tendons and ligaments, sometimes leading to stiffness and pain. If a workstation is not set up properly, these steady positions can put even greater stress on your muscles and joints.
