Your body has its own individual time

When we fall asleep and wake up, when we are hungry or can concentrate best is all controlled by our biological clock. Differences in our individual biological clock timing are the basis for being different chronotypes.

We determine your Chronotype

In this questionnaire, you’ll anonymously answer questions about your sleep times. Based on current scientific knowledge, we will use your answers to determine your individual Chronotype and amount of Social Jetlag (showing you how much you’re living against your biological timing on certain days). You will receive this information and how your results compare with others free-of-cost after filling in the questionnaire.

You’re helping us to learn more about the biological clock

So far, 250,000 people have already filled in this questionnaire. With the help of this growing, anonymous database we’ve already managed to answer many important scientific questions about chronotypes and sleep (see Publications). By participating, you’re helping us to advance our insights.
