Walking for two hours a week not only slows dementia, but boosts normal brain function as well, two new studies have found. Participants who walked less than 400 m a day were more than twice as likely to develop dementia as those who walked more than 3,2 km per day.
Walk for at least two hours per week at an easy pace of about 10-14 minutes per kilometer. The more walking you do, the healthier your cardiovascular system is, which appears to promote brain function and improve memory ability. Walking for six hours a week is most beneficial.
