One in three adults is running a sleep debt

At forty-two he watches until one in the morning and gets up at six. "Five hours is enough," he says, though he needs coffee at three every afternoon and sleeps twelve hours on weekends. CDC surveys find more than one in three U.S. adults don't get the recommended seven hours. Short sleep is linked to obesity, diabetes, high blood pressure, and heart disease. Sleep isn't the time left over after work. It's the factory that builds tomorrow's you.
