"Why Zebras Don't Get Ulcers" by Robert Sapolsky explores the impact of stress on health, particularly focusing on the differences in stress responses between humans and animals. The book illustrates how zebras, facing immediate dangers like predators, experience quick bursts of stress that help them survive, but they don't suffer prolonged stress, which can lead to health issues. Sapolsky contrasts this with humans, who often face chronic stressors, leading to various physical and psychological problems.
The author delves into the body's stress response system, explaining how hormones like cortisol can affect our overall health when released excessively. Chronic stress can contribute to conditions such as heart disease, diabetes, and depression. Sapolsky uses a mix of scientific findings and anecdotes to underscore the significance of understanding stress mechanisms, encouraging readers to recognize and manage their stressors effectively.
