Book excerpt: This book focuses on the Chinese health impact induced by ambient temperature variation, especially the epidemiology-based exposure-response relationship with the mortality and morbidity from respiratory, cardiovascular diseases, and mental health among Chinese population.A great number of epidemiological studies have reported that ambient temperature is closely associated with a wide range of health outcomes, such as mortality, cardiovascular and respiratory events, adverse birth outcome, and some infectious diseases, such as dengue fever, malaria. Although a number of epidemiological studies in western countries have evaluated the adverse health effects of ambient temperature, the exposure-response relationship from these countries cannot simply be applied to the Chinese population due to the large differences in temperature profile, exposure pattern, as well as the population vulnerability. This book will provide up-to-date estimates of the magnitude of adverse health effects of ambient temperature in the Chinese population. We hope to provide readers with a comprehensive and organized body of information in the area of Ambient Temperature and health.
