ARE YOU GETTING enough sleep? What a silly question—of course you’re not. That’s why sleep, or, more precisely, the lack of it, has become a major health concern in this country. Last year, the American Heart Association added “healthy sleep” to its Life’s Essential 8 list, which also includes healthy diet, participation in physical activity, avoidance of nicotine, healthy weight, and healthy levels of blood lipids, blood glucose, and blood pressure. Researchers are losing sleep studying how sleep-challenged you are, the many causes ranging from global warming to existential worry. So in this month of the Summer Solstice—a sleep suppressor itself, since more light means less melatonin—we decided to see what the data tells us about why we’re so sleepless in America.
