The Extra Benefits of Walking Daily You Might Not Know

Staying active can help keep your brain in good shape, say two studies that tracked exercise and mental decline over time.

And the extra benefits of walking daily are clear in these studies.

In the first, which followed more than 2,200 Hawaiian men aged 71 to 93, those who walked the least (less than a quarter mile a day) were nearly twice as likely to be diagnosed with dementia than those who walked the most (more than two miles a day) over the next seven years. Men who walked between a quarter and one mile a day had a 70 percent increased risk.

In a second study, which tracked nearly 19,000 women aged 70 to 81 for at least nine years, those who exercised the most had a 20 percent lower risk of cognitive impairment than those who exercised the least. Women who walked for at least 11/2 hours a week scored better on memory, attention, and other tests than women who walked less than 40 minutes a week.

Do Intermittent Fasting Benefits Include Living Longer?

“We’ve known for a long time that if you reduce the calorie intake of rats or mice, they live much longer,” says Mark Mattson, chief of the laboratory of neurosciences at the National Institute on Aging (NIA) in Baltimore. Do these intermittent fasting benefits carry over to humans?

What happens in species closer to humans is more complicated. Rhesus monkeys fed 30 percent fewer calories lived longer in a study at the University of Wisconsin, but not in a study at the NIA.
