During the past decade many review papers and books have been devoted to descriptions and analyses of biological rhythms (chronobiology) in plants and animals. These contributed greatly to demonstrating the impor tance of bioperiodicities in living beings in general. However, the practi cal aspects of chronobiology with regard to human health and improving the treatment of disease have not yet been a major focus of publication. One of our aims is to establish the relevance of biological rhythms to the practice of medicine. Another is to organize and convey in a simple fashion information pertinent to health- and life-science professionals so that students, researchers, and practitioners can achieve a clear and pre cise understanding of chronobiology. We have limited scientific jargon to unavoidable basic and well-defined terms and we have emphasized illus trative examples of facts and concepts rather than theories or hypotheti cal mechanisms. This volume is divided into seven chapters, each of which is compre hensive in its treatment and includes an extensive bibliography. The book is organized to serve as a textbook and/or reference handbook of modem applied chronobiology. Chapter 1 describes the historical development of chronobiology and reviews why, when, and how major concepts were introduced, accepted, and transformed."

High blood pressure (BP) (with fats and smoking) is one of the three roots of cardio-cerebro-renovascular disease affecting up to 25% of the adult population. Hence, high blood pressure should be recognized and treated, to reduce any complications and prolong life, as noted by Michael Weber of the Veterans Administration Hospital in Long Beach, California. He further emphasizes the need for monitoring before one starts the treatment of high blood pressure. Indeed, he refers to the results of the Australian study on mild hypertension with a large percentage of placebo responders and rightly suggests that many people are treated who should not be because of 'white-coat-associated high blood pressure'. He also points to the lack of standardization of techniques for data analysis and of methods of BP measurement. Ambulatory monitoring under usual condi tions without concomitant recording of events does not allow even a qualitative assessment of the impact of varying stimuli, in weber's opinion."
