In this short video, Dr. Tabatha Barber explains how the body’s natural stress response works: a real threat triggers cortisol release, adrenal activation, and the fight‑or‑flight reflex. She contrasts this acute, temporary response—illustrated by a zebra that returns to grazing after danger—with the human tendency to remain in a constant high‑cortisol state. Dr. Barber emphasizes that chronic elevation of cortisol is not what our bodies are designed for and outlines its damaging effects on major systems, including the brain, joints, and cardiovascular health.
