Now in a third edition, Robert M. Sapolskys acclaimed and successful Why Zebras Dont Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress.
As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear-and the ones that plague us now-are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer. When we worry or experience stress, our body turns on the same physiological responses that an animals does, but we do not resolve conflict in the same way-through fighting or fleeing. Over time, this activation of a stress response makes us literally sick.
Combining cutting-edge research with a healthy dose of good humor and practical advice, Why Zebras Dont Get Ulcers explains how prolonged stress causes or intensifies a range of physical and mental afflictions, including depression, ulcers, colitis, heart disease, and more. It also provides essential guidance to controlling our stress responses. This new edition promises to be the most comprehensive and engaging one yet.

We each have different ways of managing the stress in our lives. Make no mistake, we all have some stress to deal with.

One strength of this book, in comparison to other mass market books about science and health, is the emphasis on experimental science that has shaped our understanding of stress over the years.

This is preeminently the time to speak the truth, the whole truth, frankly and boldly. Nor need we shrink from honestly facing conditions in our country today. This great Nation will endure as it has endured, will revive and will prosper. So, first of all, let me assert my firm belief that the only thing we have to fear is fear itself--nameless, unreasoning, unjustified terror which paralyzes needed efforts to convert retreat into advance. It's that time of year again. No, I don't mean fall or Halloween, I mean election time. And while I get annoyed with the daily phone calls from political candidates, they remind me of what is at stake.

Why Zebras Don't Get Ulcers is a 2nd ed. The book proclaims itself as a "Guide to Stress, Stress-Related Diseases, and Coping" on the front cover of its third and most recent edition. The title derives from Sapolsky's idea that for animals such as zebras, stress is generally episodic e. Therefore, many wild animals are less susceptible than humans to chronic stress-related disorders such as ulcers , hypertension , decreased neurogenesis and increased hippocampal neuronal atrophy. However, chronic stress occurs in some social primates Sapolsky studies baboons for individuals on the lower side of the social dominance hierarchy. Sapolsky focuses on the effects of glucocorticoids on the human body, stating that such hormones may be useful to animals in the wild escaping their predators, see Fight-or-flight response but the effects on humans, when secreted at high quantities or over long periods of time, are much less desirable.

For his presentation on the effects of stress on the human body and brain contained a powerful message: stress kills slowly, suppressing the immune system, shutting down growth, and eroding memory and the ability to learn. Most frightening of all, perhaps, was the cessation of growth in seriously stressed children. Saplosky related a story about a boy from a very psychologically-abusive setting who was hospitalized in a New York hospital with zero growth hormone in his bloodstream. Over the next two months he developed a close relationship with the nurse at the hospitalundoubtedly the first normal relationship he had ever hadand soon, amazingly enough, the growth hormone levels zoomed back to normal. The nurse then went on vacation and the levels dropped again, rising once more immediately after her return. Total nightmare situations that turn out often in history.
