Why children need screen-free zones at home

The study found that bedroom TV led to screen exposure, displacing social interaction that provides stimulation for cognitive (brain), motor (movement), and emotional growth and development, which affects physical growth, brain plasticity, and socio-emotional intelligence.

Even without the violent footage and near-hysterical television anchors declaring war every minute, watching television for more than an hour every day affects the physical and mental health of children, studies show. 

Having a television in a private space like the children's bedroom amplifies the damage and affects their growth and development over the long term, say researchers.
