If you’ve ever wondered whether those brisk walks, weekend chores or garden pottering really make a difference, know that they just might keep your brain sharper as you age.

A major piece of the long-running Framingham Heart Study, that has been observing families for generations, has found that people who stay physically active in midlife or later life have a meaningfully lower risk of dementia when they get older.

The results of the study show that people  who moved the most in their 40s, 50s and 60s had about a 40 percent drop in dementia risk compared with people who barely budged. Those who kept active in their later years did even better.

Nevertheless, being active in your twenties and early thirties didn’t seem to change much at all. The study suggests the magic window for protecting your brain might be middle age and beyond, not the early, carefree years when you could sprint for the bus without pulling something.

None of this means you need to run marathons or buy fancy outfits. In fact, the researchers considered all sorts of movement, walking the dog, doing the hoovering, climbing stairs, mowing the lawn, or even getting stuck into a proper tidy-up. It all added up.

Here’s why timing matters and what a study published in JAMA network shows:

• For people whose activity levels in their midlife (roughly ages 45–64) ranked among the highest, the risk of developing dementia later was about 41 percent lower compared to those with minimal activity.

• Among those active in late life (around ages 65 and above), the dementia risk was lowered by about 45 percent for the fittest individuals.

• Early-adult activity (ages 26–44) did not show a meaningful link to dementia risk down the road. The reduced risk applied not only to general dementia, but also to dementia due to Alzheimer-type disease.
