Watching TV increases the risk of dementia.

American scientists decided to find out how different types of sedentary leisure are associated with the risk of developing dementia. It turned out that frequent watching TV is more dangerous than sitting at the computer. This can be explained by the fact that watching TV is an extremely passive activity, while spending time on a laptop involves cognitive functions. For example, users are writing emails or thinking about their next move in a video game. The study involved 146,000 people over 60 years of age, initially none of them had dementia. Over 12 years of observation, the disease developed in 3.5 thousand.
