Understanding Stress and Its Impact
What Is Stress?
Stress is the body’s natural response to a perceived threat. It triggers a cascade of physiological reactions designed to help us survive dangerous situations. However, in modern life, many of these threats are psychological rather than physical.
The Body’s Physiological Response to Stress
When we experience stress, our body activates the “fight or flight” response. This involves:
- Increased heart rate
- Elevated blood pressure
- Release of stress hormones like cortisol and adrenaline
While this response is helpful in short bursts, prolonged activation can lead to serious health problems.
Why Zebras Don’t Get Ulcers
Zebras and other wild animals experience stress only in short, life-threatening situations—like running from a predator. Once the danger is gone, their stress response shuts off. Humans, on the other hand, experience chronic stress over non-life-threatening issues like work, relationships, and finances. This prolonged stress response is what leads to ulcers and other diseases.
The Role of the Hypothalamic-Pituitary-Adrenal (HPA) Axis
The HPA axis regulates our body’s stress response. When triggered, it releases cortisol, a hormone that helps us deal with immediate danger. However, when cortisol levels remain high for extended periods, it can damage various bodily systems.
Chronic Stress and Human Health
Long-term stress is linked to multiple health issues, including:
- Cardiovascular problems – Increased risk of heart disease and high blood pressure.
- Digestive issues – Conditions like irritable bowel syndrome (IBS) and ulcers.
- Weakened immune system – Making individuals more susceptible to infections.
- Mental health disorders – Anxiety, depression, and burnout.
Stress and Modern Lifestyle
Humans experience chronic stress because our modern lifestyle constantly triggers the stress response. Deadlines, financial worries, and social pressures keep our stress systems activated far longer than nature intended.

Coping with Stress: Lessons from the Book
Sapolsky suggests several ways to manage stress, including:
- Exercise – Physical activity helps regulate stress hormones.
- Social support – Having strong relationships improves stress resilience.
- Mindfulness and relaxation – Meditation and deep breathing techniques can lower stress levels.
The Evolutionary Perspective
Stress was originally a survival mechanism, but modern society has hijacked it. Unlike our ancestors, who faced physical dangers, we deal with abstract threats that keep our stress response on overdrive.
Criticisms and Limitations of the Book
While Why Zebras Don’t Get Ulcers provides valuable insights, some critics argue that it oversimplifies certain aspects of stress and ignores recent neuroscientific discoveries. Nonetheless, it remains a compelling read for anyone interested in health and psychology.
Conclusion
Sapolsky’s book is a must-read for those looking to understand the science of stress and how to manage it. By applying the insights from Why Zebras Don’t Get Ulcers, individuals can improve their well-being and lead healthier lives.
