an hour of exercise a week 'could improve mental fitness'

Regular exercise could boost your mental fitness as well as physical, and reduce your risk of developing dementia, scientists say.

A study has found people who do more physical activity – even if it is as light as just walking – slow their brains' ageing process and are less likely to get dementia.

The findings are good news for people who try to stay fit but aren't marathon runners or Tour de France hopefuls.

The researchers say all exercise, even if it's less than the two-and-a-half hours per week recommended by the NHS, could be enough to build up and have benefits.

And every extra hour could wipe another year off someone's brain age, the research suggests.
