Exercise is among the most critical factors in reducing your risk of dementia, a new study finds.

To cut your risk of developing dementia by as much as two thirds, a new study suggests following five healthy lifestyle rules.

Most important is getting regular exercise, followed by not smoking, maintaining a low body weight, eating a healthy diet, and not drinking too much alcohol, findings suggest.

Sticking with four of the five habits could cut your risk of dementia and cognitive decline by 60 percent, as well as reduce your risks of diabetes, heart disease, and stroke by 70 percent.

Lead author Peter Elwood, from Cardiff University’s School of Medicine in the U.K., said switching to a healthy lifestyle had a “far more beneficial effect than any medical treatment or preventive procedure.”

“The size of reduction in the instance of disease owing to these simple healthy steps has really amazed us and is of enormous importance in an ageing population,” he said.

“What the research shows is that following a healthy lifestyle confers surprisingly large benefits to health — healthy behaviors have a far more beneficial effect than any medical treatment or preventive procedure.”
