There is a suggestion for parents that they should not allow their kids, aged between two and four, to watch television for long hours. The recommendation has been passed on by a group of Canadian researchers, who have found that every extra hour of watching TV will make children gain weight at the age of 10.

The study has also found a place in BioMed Central journal, in which it has been unveiled that with every extra hour of viewing television every week, children add one inch to their waistline. In order to reach at the above given result, the study researchers evaluated the TV viewing habit of 1,314 children.

After assessing the habits for two years, it was revealed that average time of watching television of children were 8.8 hours per week, but after two years it reached 14.8 hours.

Co-author of the study, Dr. Linda Pagani, from the University of Montreal, said, "Watching more television not only displaces other forms of educational and active leisurely pursuits but also places them at risk of learning inaccurate information about proper eating".

Experts have advised that children should not watch television for more than two hours and watching television for more than the said time period is not considered to be healthy.
