Americans are getting 18 minutes more sleep each weeknight than they were in 2003, according to a study published in the journal Sleep in September and reported by Niraj Chokshi in the New York Times.

Why it matters: The CDC reports that ⅓ of adults don’t get enough sleep. Insufficient sleep is linked to “linked to weight gain, focus issues and even an increased risk of Type 2 diabetes and heart disease,” writes Chokshi.
