Understanding Chronobiology

What is a Chronotype?

Your chronotype is the natural behavioral manifestation of your underlying circadian rhythm. It dictates your body's natural disposition towards sleep, wakefulness, alertness, and peak physiological performance at specific times of the solar day.

The Science of rMEQ

The reduced Morningness-Eveningness Questionnaire (rMEQ) is a psychometric questionnaire developed by Adan and Almirall in 1991. Consisting of 5 core diagnostic items extracted from the full 19-item MEQ, it offers a quick yet scientifically rigorous measure of circadian phase alignment.

Circadian Alignment

Living out of sync with your internal chronometer is linked to "social jetlag," which impacts mental health, focus, and metabolism. Aligning deep cognitive work, workouts, and sleep with your biological peaks dramatically enhances energy levels and focus.
