In this updated edition of his bestselling work, renowned primatologist Robert M. Sapolsky explains how prolonged stress can cause or intensify a range of physical and mental afflictions, including depression, ulcers, colitis, heart disease, and more. When we worry or experience stress, our body turns on the same physiological responses that an animal's boyd does, but we usually do not turn off the stress-response in the same way - through fighting, fleeing, or other quick actions. Over time, this chronic activation of the stress-response can make us literally sick. This thoroughly updated third edition, which features new chapters on sleep disorders as well as new sections on gender differences, anxiety, weight gain, post-traumatic stress disorder, and stress management, is richer than ever with insights into how the nervous system responds to stress and how those responses can be controlled.
