DUBLIN — “Too much television is bad for you” is more than just an adage parroted by exasperated parents at heedless, homework-shirking teenagers, going by research carried out by US-based scientists. Using information gleaned from three surveys and studies involving more than 17,000 people, academics from Columbia University, the University of Alabama and Johns Hopkins University (JHU) said they believe “moderate-to-high TV viewing in midlife” contributes to “later cognitive and brain health decline.” Watching films, shows and other TV content, the researchers warned, “is a type of sedentary behaviour that is cognitively passive or does not require much thought.”
