Brits who watch telly ‘a quarter less likely to develop dementia’, scientists claim

WATCHING telly helps slash your risk of dementia by nearly a quarter, scientists claim.

They said people doing “intellectual activities”, like reading or listening to the radio, are up to 23 per cent less likely to develop the disease.

Dr Lin Lu, from Peking University Hospital, reviewed 38 studies of two million people to find out who was most likely to get dementia.

He found exercising brought a 17 per cent lower risk, and social activities like volunteering cut it by seven per cent.

Dr Lu admitted the effect of watching TV needs more investigation. Past studies found too much can be a risk.

Dr Sara Imarisio, of Alzheimer’s Research UK, said: “Activities that are mentally challenging, sociable and also enjoyable are likely to be ­better for the brain than spending time alone.”

Dr Lu added: “Previous studies have shown that leisure activities are associated with various health benefits, such as a lower cancer risk.

“Our research found that activities like making crafts, playing sports or volunteering were linked to a reduced risk of dementia.”
