Want to boost your brainpower?
Get more exercise! Researchers at the University of Otago in New Zealand found that the oxygen-rich blood flooding the brain during exercise helps sharpen the mind. And adults who exercised regularly, regardless of age, performed better on difficult cognitive tasks compared with those who exercised less. And it doesn’t matter whether it’s 60 minutes of vigorous exercise, like running sprints, taking a brisk 10-minute walk around the block three or four times a day, or doing light resistance training in your own home.
