Computer Radiation

Be Aware of these: COMPUTER RADIATION!!

Computer games

#Computer and video games are popular pastimes for many children, but very little research has been done on how these games affect children’s health. Researchers believe that electronic games are associated with an increased risk of childhood obesity and can cause overuse injuries of the hand. The sedentary nature of playing electronic games could also increase the risk of developing muscle and joint problems such as back and neck pain and headaches.

#Health risks

  • Overuse injuries of the hand
  • Obesity
  • Muscle and joint problems
  • Eyestrain
  • Photosensitive epileptic seizures (rarely).

Overuse injuries

The type of injury depends on the kind of button-play performed; for example, a game that requires the player to press a button with their thumb risks injury to the thumb’s extensor tendon. Suggestions to reduce the risk of overuse injuries:

  • Set sensible time limits on game playing.
  • If available, choose the child-sized version of game controls.
  • Using unnecessary force increases the risk of overuse, so remind your child to push the buttons and other controls as gently as they can.
  • Remind them to take frequent breaks to shake, flex and relax their hands.
  • Different games often require different controls (for example keyboard, mouse, joystick, steering wheel), so encourage your child to mix up their game play.


The more hours spent in front of the television, the greater the risk of obesity. Since electronic game playing is sedentary too, researchers believe that the health effects are similar. Suggestions to reduce the risk of obesity include:

  • Set sensible time limits on game playing.
  • Offer healthy snacks and drinks while your child is playing.
  • Encourage your child to pursue other hobbies and interests, particularly sports and other physical activities.
  • Incorporate physical activities into family outings.
  • Be a good role model by participating in regular exercise and limiting your own electronic game playing.

Muscle and joint problems
Research shows that adults who work at computers for long periods of time are prone to a range of muscle and joint problems that can cause back pain, neck pain and headache.

Few studies have been done on the muscle and joint problems children may experience from game playing, but researchers believe that the impact on a child’s posture and spine may be similar. You can help to reduce the risk if you:

  • Set sensible time limits on game playing.
  • Encourage you child to take regular breaks during the game, to walk around and stretch.
  • Rearrange the furniture to suit your child’s height: for example, adjust the chair so that their feet rest flat on the floor.
  • Provide an ergonomic chair if possible, to encourage correct posture.
  • Ensure your child has enough time each day for physical activities.

Eyes that are focused at the same distance point for lengthy periods of time become fatigued. Symptoms include blurry vision and headache. To reduce the risk of eyestrain:

  • Make sure the screen is adjusted properly for contrast and brightness.
  • Rearrange the furniture if possible so that any light source, such as a window, does not shine into face or onto the monitor.
  • take frequent ‘gaze’ breaks, such as looking at distant objects to change the focal point.
  • Consult with an optometrist if your child complains of blurred vision and headache, because they might have an underlying eye problem.

Photosensitive epileptic seizures
photosensitive epilepsy is a relatively rare condition characterized by seizures in response to flickering light. A very small percentage of electronic game players may be sensitive to some games that feature rapidly flashing graphics. While the risk is extremely small, you can reduce the potential risk if you:

  • Make sure sits at least one metre back from the screen. Two metres away is even better.
  • Have a high resolution screen if possible as they are less likely to induce seizures in sensitive individuals than low resolution screens.

Things to remember

  • Set sensible time limits on computer and video game playing.
  • Your child should take regular breaks during the game.
  • Ensure your child has enough time each day for physical activities.

Computer & Health ProBleMo

We will be working mainly with the creation of imagery, rather than typing an abundant amount of text. Even so, computer users subject their bodies to many unnatural stresses, which, over time, can lead to postural difficulties, eyestrain, headaches, and repetitive-motion injuries.
Those of you who do a massive amount of typing at work, are most at risk. The standard computer keyboard is very poorly-designed, as it forces the hands into unnatural positions which strain the hand / arm / shoulder musculature.
In fact, if one wanted to deliberately devise an instrument which eventually creates the potential for debilitating injuries to the human hand, one could not find a better tool for this, than the current computer keyboard design.
So if we take a poorly-designed tool and add to this a demanding workload, the stage is set for possible injury .
Even if you don't do a lot of typing, you may still be at risk. Clicking a mouse hundreds of times per day, especially if you hold the mouse with a vise-like grip, can also lay a foundation for future dilemmas .
Another concern for computer users, is their vision. Staring at a computer monitor for hours on end, can strain the eyes. Remember to take breaks at regular intervals.
Some things you can do to avoid problems is to:
Adjust your chair so that your wrists are not bent as they sit on the keyboard .
Do NOT use the small plastic prop-ups found on some keyboards to elevate the back part of the keyboard. Propping up the rear of the keyboard, forces your hands into dorsiflexion, which sets them up for carpal tunnel-related injuries. The line created by the forearm, wrist, and hand as it types, should be a straight one .
If you have a wrist rest, do NOT place your hands on it as you type. Your hands should only rest there while pausing from typing; otherwise they should be " floating " over the keyboard. Use a light touch; don't pound the keys .
Don't grip the mouse ( or stylus ) too tightly, and try to move it with your whole arm, not just your hand, moving from the shoulder .
Take frequent breaks, stretch the muscles used, and rest your eyes .
Pay attention to warning signs .
For more information, refer to these books:
Repetitive Strain Injuries: A Computer Users Guide by Emil Pascarella MD and Deborah Quilter, Pub. John Wiley & Sons. ISBN Number: 0-471-59533-0 ( paperback). Includes information an hand and vision care and setting up your workstation.
The Carpal Tunnel Syndrome Book by Mark A. Pinsky, Pub. by Warner Books ISBN Number: 0-446-36527-0
On the Internet, a very informative piece on the subject can be found at:
If you haven't worked much with a computer before, please don't be alarmed. I am not attempting to frighten you; merely giving you some information so that you can start making conscious choices about work settings and habits .
As mentioned before, the physical stress of computer use in this class is very light, compared to use of a computer in the full-time or part-time job setting for typists or others who use the keyboard heavily every day.
It is mostly for those people, the marathon typists among you, as well as others who use their hands heavily - musicians, weightlifters, carpenters - that I present this information. Prevention really is the best policy. If you use your hands and arms continually day after day, don't wait until you sustain damage before taking action.
