Radiolab: "Stress" (April 9, 2007)
Podcast: Radiolab (WNYC Studios)
Hosts: Jad Abumrad, Robert Krulwich
Guests: Dr. Robert Sapolsky, Linda Thompson, Colby Hall
Main Theme: An exploration of stress—its evolutionary roots, how it affects the human body and mind, compelling stories of stress in action, and the science behind why some stress helps and some harms.
1. Introduction: Measuring and Hearing Stress (Start – 06:05)
-
Setting the Stage
- Host Jad Abumrad visits Cameron Falimbor, a neuropsychologist, to experience a stress test using finger sensors.
- Discussion of how anxiety creates measurable physiological changes (flow of electrons, "sparks" between fingers).
- Notable moment: Even minor disruptions, like a phone ring, make stress spike, underlining the unpredictable reality of modern life.
- Quote:
- Jad Abumrad:
“While you’re trying to de-stress, make your life a little better, the phone rings, ruins it all. One fell swoop, like life really.” [04:59] - Theme established: Stress is omnipresent and often uncontrollable, but understanding its science is possible.
- Jad Abumrad:
-
Good Stress vs. Bad Stress
- Robert Krulwich introduces the idea that some stress is necessary and even positive (“Stress is your friend. We need it in midterms… Sometimes you want it to kick you in the butt.” [06:21])
2. Stress in a Crisis: Colby Hall’s Story (06:11 – 14:16)
-
A Life-and-Death Situation
- Colby Hall recounts a traumatic water-skiing accident, where a boat propeller severely injures his legs just weeks before his wedding.
- The story highlights the surge of thoughts and decisions made in a split second—the mind negotiating survival, pain, and future hopes.
- Memorable Details:
- Even in crisis, Colby thinks about protecting children from the scene's trauma.
- His pain is blunted, and he remains oddly calm and organized.
- Afterward, previous stressors (like wedding tablecloths) seemed insignificant.
- Quote:
- Colby Hall:
“It was amazing to me how many complex thoughts you have in a split second... I don't want to die, so I'll just, you know, be in a wheelchair, or maybe I'll just be really, really injured...” [09:19] - On pain:
“It doesn’t really hurt. Like you would think that was the weird thing. Like, it didn’t hurt.” [15:22]
- Colby Hall:
-
Science Interlude – What Happens in the Body?
- Dr. Robert Sapolsky explains “tunnel vision” in traumas, how stress hormones (adrenaline) alter time perception and pain.
- Quote:
- “You shut down pain perception… Pain is a very subjective state, and if it’s the right setting, you blunt it.” [15:17]
3. The Evolution of Stress: From Savannah to Supermarkets (16:18 – 21:43)
-
The Impala Metaphor
- Sapolsky uses the example of an impala fleeing a predator: stress system floods the body for immediate survival—adrenaline releases energy, boosts heart rate, halts non-essentials like digestion and reproduction.
- Quote:
- “Your adrenaline, other hormones go to your fat cells, pour out all the stored energy, feed it to your thigh muscles…” [16:55]
-
Modern Stress vs. Ancient Stress—A Mismatch
- Today’s stressors aren’t life-threatening—they’re psychological (job anxiety, endless errands), but the body reacts identically to ancient threats.
- Quote:
- Robert Sapolsky: "What we're doing is turning on the stress response in anticipation of a stressor." [19:20]
- “If you constantly mobilize energy, you don’t store it… you’re more at risk for this disease, adult onset diabetes.” [20:58]
4. The Link Between Stress and Disease (23:02 – 27:51)
-
How the Stress-Sickness Connection Was Made
- Dr. Paul Rosch’s rodent experiments: No matter the type of stressor (physical discomfort, noise, deprivation), all made the rats physically sick.
- Not all individuals respond the same; some adapt, others fall ill—mirroring human variation.
-
Toxic Hostility: The Peril of Type A Behavior
- Robert Sapolsky details ‘toxic hostility’—a stress response pattern where the world is perceived as antagonistic. This "type A" personality is linked to higher risk of heart disease.
- Origin Story
- Discovery of the “type A” personality came from an upholsterer noticing chairs worn out in a peculiar way by fidgety, impatient patients at a cardiologist’s office.
- Quote:
- “There's a kind of anger and style that is so bad for your nervous system. That’s, like, worse than smoking, literally.” [26:46]
5. How Chronic Stress Stunts Growth: The Peter Pan Syndrome (33:48 – 37:32)
- Extreme Effects: Children Who Stop Growing
- Severe psychological stress in children can halt physical growth—documented in medical literature and the real-life story of J.M. Barrie, the author of "Peter Pan."
- Quote:
- "He'll always be my perfect little boy because he didn’t grow up. He didn’t grow up. He didn’t grow up. This kid hears this with a vengeance and stops growing." [36:07]
- Illustrates the profound ability of stress to affect physiology beyond the obvious.
6. When Body and Mind Are At Odds: Linda Thompson’s Story (38:35 – 47:51)
- Stage Fright and Hysterical Dysphonia
- British folk singer Linda Thompson describes losing her voice amidst marital and emotional turmoil (“It feels like somebody’s, you know, strangling you from the inside.” [40:09]), only to find it return—temporarily—when anger overtook heartbreak on tour.
- Memorable Moments:
- “My dysphonia… for whatever reason, I didn’t have it. I sang really well.” [43:47]
- Describes wild coping strategies on tour— smashing dressing rooms, substance use, “worse than the Sex Pistols.”
- Despite therapy and time, her voice remained capricious—sometimes present, often not.
- Quote:
- “It’s just so boring not to be able to sing. It’s boring. It really is boring having this kind of tight throat.” [45:18]
- Records a new album after 17 years, learning to “let go a little.” [47:15]
7. Coping with Stress: Lessons from Rats and Baboons (48:23 – 57:37)
-
Rat Studies: Four Paths to Alleviate Stress
-
Dr. Sapolsky’s experiments:
- Aggression: Rat can bite another to release tension.
- Distraction: Rat gnaws on wood for relief.
- Predictability: Rat can see a warning light before shock—knowledge reduces stress.
- Control: Rat presses a lever, thinking it controls shocks—even if it’s false, the sense of agency helps.
-
Quotes:
- “Make sure your outlets are not abusive ones because they feel great. They're very effective.” [50:15]
- “Control makes stressors less stress.” [51:43]
-
-
Baboons: The Importance of Social Bonds
- In his fieldwork, Sapolsky observes that former alpha male baboons fare better if they’ve formed friendships, not just dominated others.
- Baboons with affiliative relationships enjoy better social support, even increased reproductive success.
- Quote:
- “Nice guys do not finish last.” [57:37]
- Life lesson: Empathy, support, and flexible friendships can be as critical in stress resilience as any physiological mechanism.

Key Takeaways
- Stress is both friend and foe: Necessary for survival and achievement, devastating when chronic or misplaced.
- Our bodies have evolved for acute, not chronic, stress—and modern life’s constant psychological stress takes a toll.
- Social connection and positive coping strategies (friendship, predictability, even illusions of control) can greatly buffer the harms of stress.
- Understanding, not just managing, our stress roots can open the door to healthier living.
