Stress and Your Body


Robert M. Sapolsky - 2010
    Stress is an inherent aspect of life that can have tremendous negative effects on your mental and physical health. This makes coping with stress a critical part of how well we live. Once you understand the inner workings of your stress response system, you'll possess powerful knowledge that will help you understand and better deal with this common aspect of your busy life. Now, from one of the world's foremost researchers on stress and neurobiology, comes a fascinating series of 24 lectures that guide you through the psychological and psychosocial stress that is a central part of everyday life in Western society. You'll learn how the stress-response system is actually a natural survival system-giving, for example, a zebra the best chance to escape from a pursuing lion - that can change from a safety mechanism into a real problem for our physical and mental well-being. You'll see it coming into play against situations it wasn't designed to combat, such as traffic, troublesome thoughts and memories, and concerns over the economy, environment, and international events. And you'll gain valuable insights into how and why stress can affect every part of your body-including your cardiovascular, digestive, and immune systems - and learn about its relationship to important disorders and behaviors, like depression, anxiety, and even addiction.
