[Homework]2012-05-26 远离电脑远离TV 让孩子们更健康 British Kids Risking Screen Addiction
In most houses, this is a challenge, placing limits on screen time. In homes with TVs, computers, electronical games and all the rest, 10 to 11 year olds know how to have access to an average of five screen times and they regularly watch two or more at once.
The TV is on over there, ipads are on, ipods are on and if you want actually constantly show them and put a foot on them, they will be quickly happy and sit there all day.
Robert Blair doesn't have much to worry about, he is a martial art instructor and his children spend more time on the mat than the couch. The figure shows the average screen time for British adolescents is over 6 hours a day and rising. A new research claims that a generation of children is under risk for what 's being called life long screen dependence.
Doctor Alex Sidmon says being in front of the screen for too long can produce so called the walled chemicals in the brain, as seen with compulsory gamblers and other addicts. If children are producing this day after day for many hours every week during important developmental years for their brains, this is going to have the consequence later on leading to some childeren being unable to not to look at their screens most of the day.
The man behind the reseach says the answer lies in reducing the frequency and length of screen exposure. He said a child shouldn't be allowed to watch a screen until at the least age of three. And he said the government should issue guidelines on screen time to parents. In some countries, there is an official guidance that the children over seven should be restricted to two hours a day for recreational screen time. It is the latest episode in the struggle of man  against the machine.
