What is a chronotype?

2017 Nobel-Prize winning science reveals that each of us has an optimal time to fall asleep and wake up, and a biologically determined circadian rhythm known as a “chronotype.”

Your chronotype governs the peaks and dips you experience in your daily energy levels, when you are most focused, when you are most creative, and a host of other performance-related variables.
