If you're pining for better sleep, getting more exercise may help.

Participants in the 2013 Sleep in America poll who were vigorous, moderate, or light exercisers were significantly more likely than non-exercisers to report having a good night's sleep.

Vigorous exercisers reported the best sleep, but simply taking a daily 10-minute walk improved the likelihood of a restful night.
