Iowa State University of America has conducted a definitive study on effect of TV on kids. The duration of watching TV was checked against obesity, performance at the school, aggressive social behavior etc. The kind of programming and the effects were also studied.
1300 school children, their parents, teachers and dietitians took part in the study. “As screen time goes up, school performance goes down, but that does not happen overnight. If I watch a lot of TV today, I do not get bad marks in my class tomorrow,” said Douglas Gentile, an associate professor of psychology at Iowa State University.
About seven months have to pass for any good results to emerge after restricting exposure to TV, concluded the scientists. Children get more sleep if the screen time is reduced, resulting in reduced risk of obesity. Less exposure to violent programming will help kids become pro social, which will help when they grow up and move more in society.
So, parents, the sooner you start limiting TV for your kids, the faster they will get better physical health, better social behavior, better grades!
