If you’re one of the third of all Americans who suffer from insomnia -- roughly 108 million of us -- put away your sleeping pills. Science has a much safer solution.

“There has been more and more research in the last decade showing exercise can reduce insomnia,” Rush University clinical psychologist Kelly Glazer Baron said.

“It’s less expensive, healthier and just as easy to exercise,” sleep researcher Shawn Youngstedt said, “and there’s an added bonus: Research suggests those who are physically active a have lower risk of developing insomnia in the first place.”
