Even light activity such as household chores might help to keep the brain young, researchers say, adding to a growing body of evidence that, when it comes to exercise, every little helps.
The findings mirror upcoming guidance from the UK chief medical officers, and existing US guidelines, which say light activity or very short bouts of exercise are beneficial to health – even if it is just a minute or two at a time – countering the previous view that there was a threshold that must be reached before there were significant benefits.
“Our study results don’t discount moderate or vigorous physical activity as being important for healthy ageing. We are just adding to the science, suggesting that light-intensity physical activity might be important too, especially for the brain,” said Dr Nicole Spartarno, first author of the study from Boston University, adding that light activity might include a gentle walk or household chores.
