Are you a morning person? A night owl?
Your preferred sleep pattern is called your “chronotype,” and if you’re forcing yourself to live outside your natural circadian pattern—a night owl jarred awake early by an alarm clock, for example, or an early bird who stays up late working or partying—it’s not just a matter of feeling tired. You’re at risk for depression, poor memory, obesity and even some kinds of cancer. But the demands of work, school and society—and the convenience of artificial lighting—make it hard for many people to listen to their own body clocks.
Unless, that is, they live in Bad Kissingen, a small spa town on the southern edge of Germany’s Rhön Mountains. (Bad means “bath” in German.)
