What is a chronotype?

Your genetic, pre-determined sleep schedule.

Why are chronotypes important?

Your chronotype = your hormone schedule.

How do I find my chronotype?

Take our chronotype quiz here!

You’ve likely heard the phrase biological clock, but do you know what yours actually says about you?

Your biological clock dictates multiple processes in your body, including circadian rhythms like alertness and sleepiness, appetite, and mood changes throughout the day. Some people feel more energized and productive in the morning whereas others don’t hit their prime until later in the evening.

These peaks and valleys are determined by your chronotype – your natural, genetic inclination to do certain things at certain times.

Chronotypes fall on a spectrum, with four categories represented by animals: bear, lion, wolf, and dolphin. Understanding your chronotype can help you to optimize your schedule to get the most out of your days (and nights).
