A study found that walking about 5 miles a week, or 20 minutes a day keeps the brain volume stable.

The ongoing 20-year study found that walking for about 6 miles a week, or 20 minutes a day, over the years, keeps the brain volume stable and prevents the development of diseases such as Alzheimer’s, senile dementia and MCI.

According to information from BBC News Researchers the habits of more than 400 seniors with an average age of 80 years were studied at the University of Pittsburgh over the past two decades. 299 study participiants Of the total number of 426, were healthy people, while others suffered from Alzheimer’s or dementia. This study showed that greater physical activity increases brain volume, precisely the brain’s gray matter volume associated with memory issues.

The results also showed that the earlier in life you start the habit of walking, the less likely is to suffer from dementia.
