A new study suggests the Fountain of Youth and your own sweat glands may be one in the same. 

The only catch? You'll need to hit the gym more than once after Jan. 2.

Research published in the journal Medicine & Science in Sports & Exercise suggests regular exercise can fight cognitive decline. In other words, routine sweat sessions can keep your brain young.    

Researchers equipped 6,400 people over the age of 65 with activity trackers for a week. They also assessed participants’ cognitive abilities via several tasks.

Three years later, those who engaged in moderate-to-vigorous amounts of physical activity had a 36 percent lower risk of cognitive impairment, compared to those who were sedentary or did light physical activity.

Those who’d done moderate-to-vigorous exercise also had better memory and executive function than those who did less.

This most recent study adds to the growing body of evidence that exercise is linked to better brain health. Past studies have shown that exercise can improve blood flow to the brain, as well as lower your risk for a range of chronic diseases, including diabetes and obesity.
