This is Your Brain on Walking
Exercise, such as walking, increases the blood flow to the brain. A 1999 study of people over age 60 found that walking 45 minutes a day at a 16-minute mile pace improved thinking skills. The participants started at 15 minutes of walking and built up their time and speed. The result was that the same people were mentally sharper after taking up this walking program.
A study in 2011 showed that older adults walking 40 minutes a day, three times a week, reduced the normal age-related shrinkage of the brain's hippocampus, which is where the brain processes memory and emotions. After a year, they improved their performance on spatial memory tasks.
Get smart - get walking.
