The stress response: in the beginning it saved our lives, making us run from predators and enabling us to take down prey. Today, human beings are turning on the same life-saving physical reaction to cope with 30-year mortgages, $4 a gallon gasoline, final exams, difficult bosses and even traffic jams — we can't seem to turn it off. So, we're constantly marinating in corrosive hormones triggered by the stress response.
Now, scientists are showing just how measurable — and dangerous — prolonged exposure to stress can be. Stanford University neurobiologist, MacArthur "genius" grant recipient, and renowned author Robert Sapolsky reveals new answers to why and how chronic stress is threatening our lives in Killer Stress, a National Geographic Special. The hour-long co-production of National Geographic Television and Stanford University was produced exclusively for public television.
In this revelatory film, discoveries occur in an extraordinary range of places, from baboon troops on the plains of East Africa to the office cubes of government bureaucrats in London to neuroscience labs at the nation's leading research universities. Groundbreaking research reveals surprising facts about the impact of stress on our bodies: how it can shrink our brains, add fat to our bellies and even unravel our chromosomes. Understanding how stress works can help us figure out ways to combat it and mitigate negative impacts on our health.
For over three decades, Robert Sapolsky has been working to advance our understanding of stress — in particular how our social standing (our place in various hierarchies) can make us more or less susceptible to the damaging effects of stress. Throughout the film, he weaves the grim realities of the impact of chronic stress with his wry observations about 21st century life. "The reality is I am unbelievably stressed and Type A and poorly coping," says Sapolsky. "Why else would I study this stuff 80 hours a week? No doubt everything I advise is going to lose all its credibility if I keel over dead from a heart attack in my early 50s. I'm not good at dealing with stress. But one thing that works to my advantage is I love my work. I love every aspect of it."
The film is based partly on Sapolsky's best-selling book Why Zebras Don't Get Ulcers: Stress, Disease and Coping. In addition to his professorship at Stanford, Sapolsky is a research associate with the Institute of Primate Research at the National Museum of Kenya. He is also the author of Monkeyluv, A Primate's Memoir and The Trouble with Testosterone, a Los Angeles Times Book Award finalist.
Scientists from the University of North Carolina, the University of London, Rockefeller University and the University of California, San Francisco share their compelling insights into how stress impacts the body, giving stress a new relevance and urgency to our increasingly complex lives.
