Designed as an "operator's manual", this text introduces students and lay readers to the subject of human chronobiology. It describes biological clocks and the methods used to measure rhythms of humans and animals. It explains how humans are synchronized with a 24-hour environment using time cues and how external time cue deprivation affects acitivity and rest time in the individual's inherited "biological watch". In addition, this volume details how the human clock adjusts to travel across time zones, shift work alterations, and change between standard and daylight time. It contains information and blank forms so that the reader can measure his own rhythms and apply the results to improve daily activity and wellness.
