Those of us who started to study human circadian rhythms in the 1970s remember quite fondly a book by Gay Luce, Body Time (Pantheon Books, 1971), which gave the lay reader a rather nice introduction to the area. Most lay books since then have been rather selective and/or sensational, and have lacked the depth and authority of Luce's book. Now, a quarter of a century later, we have a worthy successor, written by Lynne Lamberg.

Bodyrhythms: Chronobiology and Peak Performance aims to introduce the reader to human chronobiology in general. Thus, although the topics of circadian rhythms and sleep predominate, attention is also given to infradian rhythms, such as the menstrual cycle. The book is divided into three parts: how body clocks work; mending broken clocks; and body clocks and modern life, a detailed consideration of jet lag, shiftwork, and the need for better work schedules.

The author is a medical journalist who became interested in the area in the 1980s when she was commissioned to write the American Medical Association Guide to Better Sleep. Bodyrhythms has a slightly academic, albeit very readable, approach with more than twenty pages of references and an excellent glossary. Useful appendices include how to cope after missed sleep and a shiftwork coping guide.

Throughout the book, one is pleased to see the fruits of Lamberg's diligent research which has clearly involved detailed conversations with the major players, rather than a reliance on secondary sources. Indeed, Bodyrhythms attains the level needed to become a teaching aid for students, as well as one's more academically minded patients. This reviewer has taught a course for postdoctoral fellows and postgraduates based directly on the book, finding it to work very well.
