Renowned primatologist Robert Sapolsky offers a completely revised and updated edition of his most popular work, with nearly 90,000 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.
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.
