Several researches around the world has shown that on an average children who consistently spend more than 4 hours per day watching TV are more likely to be overweight. In earlier days before the television, children played outdoors more and used their minds to be more creative. Today, obesity is a major problem among children and health experts point out that television plays a major role in this. Excessive television viewing promotes inactivity and when it is combined with frequent snaking it leads to obesity. In addition, children are more and more influenced by advertisement and through television they're also bombarded with messages that encourage them to eat unhealthy foods such as potato chips and empty-calorie soft drinks that often become preferred snack foods.
There is no doubt that television has its good side. It can be both entertaining as well as educational. It gives good opportunity for children to learn more about different cultures, and gain exposure to ideas they may never encounter in their own community.Besides, it also gives them a chance to see different places and learn about various aspects on culture in different parts of the world. However, if we think of a situation where there was no television, children who have an interest to learn about these aspects could use books and other sources to know about these things.
