Discover Your Natural
Sleep-Wake Rhythm

Your chronotype is your body’s natural preference for when you feel most alert, focused, energetic, and ready for sleep. 

Understanding your chronotype can help you optimize sleep quality, cognitive performance, productivity, exercise timing, and overall longevity.

This assessment is inspired by decades of circadian rhythm research, including the Morningness-Eveningness Questionnaire (MEQ) originally developed by Horne and Östberg.

Please answer based on your natural tendencies, not your current work schedule or obligations.
