When people burdened with stress start to feel bad physically, it is not just in their minds. Emotional crises bring on specific physical changes in the body. If those stress responses are prolonged or set in motion too often, the resulting wear and tear can lead to digestive and sleeping problems, heart disease, cerebrovascular diseases, reproductive disorders and other illnesses. "Why Zebras Don"t Get Ulcers" is Robert Sapolsky"s look at the interconnections between emotion and physical well-being. Drawing on the latest research, Sapolsky describes the physical toll associated with emotional turmoil. He also discusses some proven effective ways of learning to moderate the body"s responses to stress. This book"s balance of biology and psychology, and research-supported suggestions for coping, should make it a helpful guidebook for people worried about worrying themselves sick.
