Exercise
You knew that physical activity was good for your heart, but did you realize it can literally pump up your brain? Researchers at the University of British Columbia found that aerobic exercise actually increases the size of the hippocampus, the part of the brain associated with memory storage.
Recommendation: The American Heart Association recommends at least 150 minutes a week of moderate aerobic activity, like brisk walking, or 75 minutes of vigorous aerobic activity, like jogging or swimming.
