Be careful all parents Too much TV bad for children

SYDNEY: A new study reveals that children who spend too much time watching TV are at a higher risk of developing several health problems later in life.

The study conducted by the University of Sydney in Australia found that 6 to 7-year-olds who spent the most time in front of the TV had narrower arteries in the back of their eyes, which increases their chances of developing heart disease, high blood pressure and diabetes when they are older.

Dr. Bamini Gopinath, the study’s lead author, said: "Parents need to get their children up and moving and off the couch."

The first-of-its-kind study involved 1,500 children in 34 primary schools in Sydney.

On average, children spent almost two hours a day in front of a TV or computer screen and just 36 minutes in organized physical activity.

But those with the highest level of activity – more than an hour or so – had significantly wider retinal arteries than those who spent less than 30 minutes.

The damage appears to be caused by a combination of concentrating for too long on the screen and not getting enough exercise.

“This suggests unhealthy lifestyle factors may influence microcirculation early in life and increase the risk of heart disease and high blood pressure later in life," Gopinath added.
