America, you need to take a nap. The CDC notes that 30 percent of U.S. adults get less than six hours of sleep a night, rather than the recommended seven to eight. Less than one-third of American high school students get eight hours of shut-eye a night, even though they should be getting nine to 10 hours regularly.
Most of the Midwest is going to bed on time—South Dakota ranks first among the best sleepers—but the eastern side of the U.S. needs to take a nap. The vast majority of the states that get the least sleep are east of Illinois—with the notable exception of Vermont, where 69 percent of the population gets seven-plus hours of sleep a night. We assume that everyone there lives in a forest cabin and rises and sleeps with the sun. Or maybe all that maple syrup makes people sleepy.
You may be asking, "Where's Hawaii?" The island state is a bit hard to spot because it's very, very pale. Hawaii is the nation’s most sleep-deprived state, with only 56 percent of adults getting their recommended seven hours.
The CDC's data is based on self-reported sleep times, so these statistics may not be exact. You can scroll through the full list of states and how much of their population is well-rested over on STAT.
