Chronobiology

847 Articles 42 Expert Contributors Last updated: Oct 24, 2025

Chronobiology is the scientific study of biological rhythms and their synchronization with environmental cycles. This discipline encompasses circadian, circannual, tidal, and lunar rhythms, exploring how internal biological clocks regulate physiology, behavior, and metabolism across species. Our coverage spans molecular genetics, neurobiology, ecology, and clinical applications like chronotherapy.
