Quiz: What Is Your Chronotype?

Learn why you have the sleep problems you do and how to solve them with this quiz created by Dr. Michael Breus.

You chronotype, or biological clock, affects your sleeping habits.

A chronotype is your own personal biological clock that controls your body's rhythms. It's the reason you are grumpier in the morning or focus better later in the day. This genetic biological clock affects much more than your waking and sleeping patterns. It affects when you should eat; when the best time for coffee is; and when you should socialize, work and exercise, among other things. Find out if your chronotype is a lion, dolphin, bear, or wolf, and how these types impact your sleep and habits.
