The effects of TV I see in my house is eye sight problems, eating in front of the TV and so eating more, plus lack of communication.
My son insists on sitting very close to the TV and watching it. I always warn him and have him sit back, but I think his babysitter has not said anything. I also think it's the reason for his bad eye sight, he is 9 years old and wearing glasses now. Neither my husband nor I wear glasses.
Another thing my husband tends to do is eat in front of the TV, especially if there is something we just can't afford to miss, like a game or a favorite show. I have read articles that say people eat more in front of the TV and eat unhealthier because snack foods are easier to have.
We are also not talking to family members when we are watching TV. I think in the long run, this may cause stress and strain in relationships. It might even lead to depression because if people watch too much TV. I feel depressed and sad if I'm not interacting with people and have a social life. TV is a great way to hide and stay away from society.
