Book Description
The physiology of man is a complex subject. Unfortunately the regulation of temperature in the human body is not always well explained in textbooks. Many conference proceedings on the subject have been produced that give excellent detail on research topics. However, the subject matter is rarely presented as a composite whole. New technology has broadened the scope of methods available for studying body temperature. Thermography in particular has made it possible to record in real time the temperature distribution of large areas of the body surface. Modem image processing methods permit dynamic studies to be carried out and detailed analyses made retrospectively-a tremendous advance over the complex and slow techniques formerly used by physiologists. Yet although the associa tion between disease and temperature is as old as medicine itself, beyond the implicit faith in the clinical mercury thermometer, other measuring techniques are finding a slow acceptance. This book is designed to put into perspective the critical factors that make up "body temperature. " Body temperature cannot be viewed as a static entity but rather must be seen as a dynamic process. An understanding of this phenomenon is important to all who use thermal imaging and measuring techniques in clinical medi cine. These methods have, in recent years, brought engineers, physi cists, technicians, and clinicians together. Inevitably, however, there v vi Preface are gaps and overlaps in technology and understanding.

Book Description
Our responses to our thermal environment have a considerable effect on our performance and behavior, not least in the realm of work. There has been considerable scientific investigation of these responses and formal methods have been developed for environmental evaluation and design. In recent years these have been developed to the extent that detailed national and international standards of practice have now become feasible. This new edition of Ken Parson's definitive text brings us back up to date. He covers hot, moderate and cold environments, and defines these in terms of six basic parameters: air temperature, radiate temperature, humidity, air velocity, clothing worn, and the person's activity. There is a focus on the principles and practice of human response, which incorporates psychology, physiology and environmental physics with applied ergonomics. Water requirements, computer modeling and computer-aided design are brought in, as are current standards. Special populations, such as the aged or disabled and specialist environments such as those found in vehicles are also considered. This book continues to be the standard text for the design of environments for humans to live and work safely, comfortably and effectively, and for the design of materials which help the same people cope with their environments.

Book Description
The principal objective of this book is to provide information needed to define human thermal behavior quantitatively. Human thermal physiology is defined using mathematical methods routinely employed by physicists and engineers, but seldom used by physiologists. Major sections of the book are devoted to blood flow, sweating, shivering, heat transfer within the body, and heat and mass transfer from skin and clothing to the environment. Simple algebraic models based on experimental data from a century of physiological investigation are developed for bodily processes. The book offers an invaluable source of information for physiologists and physical scientists interested in quantitative approaches to the fascinating field of human thermoregulation.

Book Description
Whether you're a polar bear giving birth to cubs in an Arctic winter, a camel going days without water in the desert heat, or merely a suburbanite without air conditioning in a heat wave, your comfort and even survival depend on how well you adapt to extreme temperatures. In this entertaining and illuminating book, biopsychologist Mark Blumberg explores the many ways that temperature rules the lives of all animals (including us). He moves from the physical principles that govern the flow of heat in and out of our bodies to the many complex evolutionary devices animals use to exploit those principles for their own benefit. In the process Blumberg tells wonderful stories of evolutionary and scientific ingenuity--how penguins withstand Antarctic winters by huddling together by the thousands, how vulnerable embryos of many species are to extremes of temperature during their development, why people survive hour-long drowning accidents in winter but not in summer, how certain plants generate heat (the skunk cabbage enough to melt snow around it). We also hear of systems gone awry--how desert species given too much water can drink themselves into bloated immobility, why anorexics often complain of feeling cold, and why you can't sleep if the room is too hot or too cold. After reading this book, you'll never look at a thermostat in quite the same way again. Table of Contents: Introduction 1. Temperature: A User's Guide 2. Behave Yourself 3. Then Bake at 98.6°F for 400,000 Minutes 4. Everything in Its Place 5. Cold New World 6. Fever All through the Night 7. The Heat of Passion 8. Livin' off the Fat 9. The Light Goes Out Epilogue Bibliography Acknowledgments Index Reviews of this book: There's a little twinkle in Mark Blumberg's eye as he explains the role of temperature in life on Earth, that essential gleam that makes books about science successful and appealing...His writing is clear, a fine balance of explanation, example and ideas. --Susan Salter Reynolds, Los Angeles Times Book Review Reviews of this book: The need to maintain body temperature within a narrow range is the biggest single influence on physiology and behaviour, as Mark Blumberg explains in this little gem of a book, Body Heat...Blumberg describes the exquisite mechanisms developed by different species to generate, conserve or lose body heat. --John Bonner, New Scientist Reviews of this book: This is one of those books that leaves you for a few heady days in possession of a new key to all mysteries. Written entertainingly for a popular audience, the book argues that the evolved behaviour and physical characteristics of most creatures, from the tiniest nematode worm to the largest whale, is governed by the need to maintain a comfortable body temperature. --Emma Crichton-Miller, The Telegraph Reviews of this book: Blumberg...presents a thoroughly interesting book on body temperature and its many influences, loaded with a marvelously broad range of topics related to the biology of body temperature. From structural adaptations, such as ear size, circulatory patterns, and body shape that have evolved to help maintain body temperature, to psychological effects of temperature, the physiology of fevers, and even sexual-thermal metaphors used in everyday conversation. A host of fascinating aspects of how species respond to temperature changes are also discussed...Body Heat is great reading, certain to produce an enlightened appreciation for how body temperature control is critical for all organisms. --M. A. Palladino, Choice Reviews of this book: Mark S. Blumberg, in Body Heat, also takes the role of temperature in human affairs onto a global stage, but his metaphors, languages and conclusions are neither biblical nor prophetic. Instead he wants to remind us just how narrow our margins of tolerance are against that ultimate enemy: cold...Blumberg loves his subject, is convinced of its importance, and he wants to put across the intrinsic interest of temperature physiology to a larger audience. He retains a light touch--and because he is an active researcher in his own right, is able to bring new information and new insights to his pages. --Jonathan Kingdon, Times Literary Supplement This book is a real treat. Mark Blumberg takes something we normally hardly think about, and makes it into a fascinating topic, with colorful examples from fields as disparate as etymology and entomology. You probably will be repeating many of the stories he tells to those around you, as you discover why a fever may be good for you, or how babies generate their own heat, or how eating disorders interact with body temperature problems. It's entertaining, interesting, and great fun. --Michael Leon, University of California, Irvine This is an engaging enchilada of a book, wrapping up cold feet, a warm heart, hot sex, and chili peppers, for easy digestion by the general science consumer. Delicious! --Bernd Heinrich, University of Vermont, and author of The Hot-Blooded Insects: Strategies and Mechanisms of Thermoregulation

Book Description
How do mammals manage to maintain their body temperature within the same narrow range in environments as different as polar regions and hot deserts? This advanced text describes the morphological features and physiological mechanisms by which humans and other mammals maintain their body temperature within a narrow range despite large variations in climatic conditions and internal heat production. Its 19 chapters deal with the physics of heat exchange with the environment, and the autonomic and behavioural mechanisms available to control the loss and production of heat. The neuronal basis of temperature regulation and current concepts of the central nervous interface between temperature signals generated in the body and control mechanisms are examined in detail. This book is of invaluable help for undergraduates, postgraduates, teachers, physicians and scientists.
