We already knew that television could have negative effects on children. But this study has shown that the small screen could also affect people aged 50 years and older.
Watching too much TV can have negative effects on people over 50, even to the point of increasing their risk of dementia. This is the conclusion of a study conducted by University College London. For six years, researchers observed people over 50 years old. And the results are very clear. Those who watch television more than 3.5 hours a day have lost 10% of their vocabulary. Against only 5% for those who spend less time in front of the small screen.
An activity that isn't stimulating enough
How come? This activity does not stimulate the brain enough.
"People over the age of 50 should make sure that television time is offset by other activities," said Daisy Fancourt, one of the researchers.
While they don't necessarily have to stop watching television altogether, activities such as games or discovering new hobbies are preferable.
This study, led by Daisy Fancourt and Andrew Steptoe, is one of the first to study the impact of television on older people. So far, research has been focused on children.
