Why Zebras Don't Get Ulcers, Third Edition Paperback – September 15, 2004
Purchase options and add-ons
Renowned primatologist Robert Sapolsky offers a completely revised and updated edition of his most popular work, with over 225,000 copies in print
Now in a third edition, Robert M. Sapolsky's acclaimed and successful Why Zebras Don't 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 animal's 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 Don't 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.

Editorial Reviews
Review
"Robert M. Sapolsky is one of the best science writers of our time."―Oliver Sacks
For the first edition of Why Zebras Don't Get Ulcers:
Sapolsky succeeds in interpreting technical material in a way that leaves readers with an understanding of how the same physiological responses, so well suited for dealing with short-term physical emergencies, can turn into potential disasters when chronically provoked for psychological or other reasons....The author has a way with words and images....you'll find plenty to intrigue you. ―The Washington Post
Robert Sapolsky wittily dissects the anatomy of human stress-response. ―The Wall Street Journal

From Why Zebras Don't Get Ulcers:
Regardless of how poorly we are getting along with a family member or how incensed we are about losing a parking spot, we rarely settle that sort of thing with a fistfight. Likewise, it is a rare event when we have to stalk and personally wrestle down our dinner. Essentially, we humans live well enough and long enough, and are smart enough, to generate all sorts of stressful events purely in our heads. How many hippos worry about whether Social Security is going to last as long as they will, or even what they are going to say on a first date? Viewed from the perspective of the evolution of the human kingdom, psychological stress is a recent invention. If someone has just signed the order to hire a hated rival after months of plotting and maneuvering, her physiological responses might be shockingly similar to those of a savanna baboon who has just lunged and slashed the face of a competitor. And if someone spends months on end twisting his innards in anxiety, anger, and tension over some emotional problem, this might very well lead to illness.

- Reviewed in the United States on November 5, 2009If I got to make a list of people on this planet I'd like to meet, Robert Sapolsky would be one of them. This guy is brilliant, hysterical, accessible, and informative in thousands of different ways. His writing can be extremely technical, explaining the details of hormones and neuroscience on every page --- but then goes on to give vivid, delightful illustrations of how those "invisible" forces in our bodies show up in the real world. In us. And in baboons. Other animals. And zebras (hence, the title.)
The purpose is to illustrate why we, as individuals, and a Western society, experience stress, and how it manifests as sickness in so many ways. Real sickness, with short term results and long term diseases. In our bodies, not "in our minds", not something we should just "get over". His words and proof is validating scientifically, and a call to action. Our behavior, and the structure of our society, is making us sick. It's not humane to do what we do to ourselves. And we can change this.
I'd like to see this book as mandatory reading for every policy-maker in health and human services. But I certainly wouldn't stop there. Managers, top to bottom, need it to understand the pressures on their employees and organizations. Scientists who work with people, or whose work affects people. Anyone who causes, or experiences, stress. Hmmm....does that leave anyone out?
Okay, not everyone will want to read this book, because it's pretty technical, not designed for an uneducated reader. But the lessons in it are for everyone. I understand Sapolsky is regarded as one of the top neuroscientists in the world, and that's no surprise. What I'm grateful for is that he shares his knowledge in something other than a scientific journal, and it's an amazing read. It will be on my reference shelf permanently, but unlike the others which I use for "reference" --- I will also read it often just because it's a great read. Imagine that.
- Reviewed in the United States on December 16, 2012This is an incredibly engaging and informative book. In just over 400 pages, Sapolsky covers all aspects of stress, from what exactly stress is at the chemical level, to how stress effects sleep, the immune system, and sex, to practical ways of coping with stress.
This book contains a significant amount of technical discussion. For example, the author goes into detail about the release of stress hormones such as cortisol and norepinephrine. That being said the writing is still clear and easy to follow, even if you do not have a background in medicine or physiology.
In addition to considering the physiological aspects of stress, the author also talks considerably about the psychological aspects of stress. He writes for example about studies of attachment style, and what kinds of childhood environments lead to stress later in life.
Surprisingly, another treat about this book is the footnotes. The author shares humorous and informative anecdotes here such as why JFK had a bad back, the inner working of toilet bowls, and why hormones have their names.
I've tremendously enjoyed reading this book, and also Sapolsky's other book 'A Primates Memoir'. He makes science fun to read, and is world-class in his field. Granted the book is long, and the fact that the topic is stress all the way through did make it go slowly in some places. Nevertheless, if you have an interest in science, are not thrown off by technical discussions, and are looking for an eye-opening read then I'd recommend you give this book a go.
- Reviewed in the United States on September 30, 2024Influence of and elevation in glucocorticoids can effect your overall stress levels and can effect multiple functions and in multiple areas both physical and mentally. Stress is everywhere.
- Reviewed in the United States on July 5, 2021Stress can take its toll on the human body. This isn’t a new idea- most everyone agrees that prolonged exposure to stressful situations can have negative impacts on overall health and well- being. Just how, exactly, does stress affect our bodies and is there a way to reduce its harm? These are subjects tackled in Why Zebras Don’t Get Ulcers.
This book combines social science with traditional science to explain how stress impacts our lives. The book serves up a healthy dose of science as it explains the different body chemicals that are released in response to a stressful event. It explains what these different hormones do and offers up studies and evidence that show what can happen if stress isn’t brought under control.
The title of this book is one that gets your attention and convinces many to read. It’s a metaphor that continues to pop up throughout the reading. It effectively drives home many of the books key points, using a zebra being pursued by a lion as its basis. The book serves up a healthy dose of humor, too, which helps keep things interesting and keeps your attention.
As I read this book, I started thinking more than usual about my own levels of stress and whether I have been negatively affected by stress to a noticeable degree. I feel like I have stress under control, at least better than I used to. I don’t overreact to things like I once did and it’s a good thing I don’t. After reading this book and discovering what stress can do to you, I was tempted to quit my job, sell my urban home, and move to a secluded part of the country.
Stress is detrimental and it is something we all need less of in our lives. Why Zebras Don’t Get Ulcers is a highly useful book for understanding the science behind the stress and all the harm that stress can inflict. It’s a well- written book that explains the science with a dash of humor to keep it entertaining enough that you want to continue reading. I learned quite a bit and it has piqued my interest to continue pursuing more knowledge about stress and its impact on our bodies.

- Reviewed in the United States on April 15, 2024This fellow Sapolsky is a rare combination - a brilliant scientist as well as a very amusing and talented writer. Immediately went out and bought Behave as well. Thought provoking and often hilarious, mostly written in a way a practical layman can (mostly) understand.

5.0 out of 5 stars Read this book and find out how to live longer and better.
Stupendous book. Every human being in the western world, and certainly every politician, should be forced to read this book (or a simplified version for the less mentally agile!), as it explains why we are slowly killing ourselves with a combination of stress and unhealthy behaviours, especially around diet and exercise. The recurring theme is how the fight or flight response to long-lasting stressful situations (for which it was not "designed", if designed it was) is now doing so much damage to 21st century human bodies and, by its effects on the HPA axis (cortisone etc), is creating virtually all the major illnesses from which we are either dying or ending up being a drain on our health care systems. It's a very long book, and, to be honest, I haven't finished it, as it is very hard going (but see below), but I know I must continue to read it, and read it again, as it is the most important and informative book I think I will ever read. I say it is hard going, but not only is Robert Sapolsky clearly a great scientist, he is also a very funny man who livens the text with entertaining anecdotes and self-deprecating comments. If you want a gentle way into the book search youtube for The Lion The Watch and The Hormones, a brief music video by Tom McFadden about the book, in which Robert Sapolsky himself makes what might be called a cameo role. Buy this book, read it and find out how to live longer.

5.0 out of 5 stars An Outstanding Book
The author, Robert M. Sapolsky, has done a super job with this book. There a lot of research that was used to write it and it provides a balanced view point on stress and other subjects giving due regards to the state of the art.
For a laymen like me, this book was a mouthful. Yet, the author did an excellent job to introduce the medical terminology and the concepts, gradually, as you progress, and by the time I was through the book, I was surprised as to how much I had learned. I certainly will go back to it periodically so I don't loose what I've learned.
I think that this book is well worth buying and studying. It provides a lot of valuable advice that you can use to maintain and improve your health in a number of ways.
Thumbs up for Professor Sapolsy!
