The National Sleep Foundation’s 2013 Sleep in America® poll shows a compelling association between exercise and better sleep. Participants were asked to identify how often they exercised and how well they usually slept. Researchers discovered that those who exercised more often reported better sleep. In fact, the participants who identified themselves as ‘vigorous’ exercisers were almost twice as likely as non-exercisers to report sleeping well every night and were the least likely of all participants to report sleep problems. More than two-thirds of vigorous exercisers said they rarely or never had symptoms commonly associated with insomnia.
