It’s true, zebras don’t get ulcers. For one thing, they don’t worry about things that are probably not even going to happen. Ever. Humans are the only ones who have that ability, and very often when we worry our body turns on a stress response, flooding it with a number of stress hormones that will promote a series of changes in our organs and our natural balance – heart rate goes up, immune system is suppressed, blood is diverted to muscles or wherever is most needed… Basically we have evolved to turn on a fight-or-flight response like zebras and other animals, however, unlike zebras and other animals, we don’t turn it off as easily – and that’s because most of the time we don’t react to threats, but to perceived threats.
This is one of the basis to chronic stress. And we know that chronic stress can damage our body in many ways. It doesn’t necessarily means chronic stress is the cause to several diseases. It means that chronic stress, by permanently altering the body’s homeostasis, creates an environment in which it becomes impossible for the body to fight other factors, such as genetic predispositions or environmental risks. This is true for autoimmune diseases but also for heart conditions, ulcers, depression and many more.
Why Zebras Don’t Get Ulcers is the bible of stress. It’s not a book about a specific disease, it it rather a book about how stress can pave the way to many diseases. Each chapter focuses on a different system: cardiovascular, respiratory, endocrine, digestive, immune, reproductive… It also includes chapters on sleep, pain, memory, depression and anxiety, and addictions. And it doesn’t leave you with that. It includes insights on stress management, coping styles and how personality and temperament come into play.
The book is rather long and at certain points can become a little technical, but it is also filled with humor, relevant research and even the author’s personal experiences. If you needed further proof that you need to work on all that stress that invades your life uninvited, then this is the book to turn to.
