Jürgen Aschoff

Jürgen Aschoff was a German biologist who co-developed the field of chronobiology, studying biological rhythms such as sleep-wake cycles. His research helped reveal that our bodies have internal clocks, called circadian rhythms, which regulate daily functions like sleeping, eating, and hormone release. Aschoff’s experiments showed these rhythms are influenced both internally and by external cues like light. His work improved understanding of sleep disorders and how our biology aligns with the day-night cycle, impacting health and medicine.
