Stress Simplified: Understanding the Impact of Stress

Christian Flagg Published: February 11, 2025 6 mins read

Introduction

 

Imagine you’re a zebra, grazing peacefully on the African savanna. Suddenly, a lion charges. Your body floods with adrenaline, your heart pounds, and you sprint for your life. But here’s the difference between zebras and humans: once the zebra escapes, it shakes off the stress—literally—and goes back to grazing like nothing happened.

 

Now, picture yourself stuck in traffic, late for a meeting. Your body reacts the same way—heart pounding, stress hormones surging—but instead of escaping, you stew in it. The stress doesn’t stop. Unlike the zebra, you carry the lion with you—in your emails, your to-do lists, and your overthinking brain.

 

That’s the real problem. Stress itself isn’t bad. It’s chronic stress—the kind that lingers in the background like an annoying app draining your phone battery—that wreaks havoc on our health.

 

So how do we stop carrying the lion? Let’s break it down, using science-backed insights from top researchers like Robert Sapolsky, Kelly McGonigal, and Andrew Huberman.

🧠 I. What Is Stress? A Simplified Explanation

 

The Science of Stress: Hans Selye’s Groundbreaking Work

 

Stress is not just “feeling overwhelmed”—it’s a biological response. Hans Selye, the “father of stress research,” found that stress follows a three-stage pattern:

 

  1. Alarm Stage: Your body detects a threat (real or perceived) and activates the fight-or-flight response.
  2. Resistance Stage: If stress continues, your body tries to adapt but stays in high alert.
  3. Exhaustion Stage: Over time, prolonged stress wears you down, leading to burnout, illness, and emotional fatigue.

 

Eustress vs. Distress: Not All Stress Is Bad

 

Not all stress is evil—it depends on how we perceive it.

 

  • Eustress (Good Stress): Motivates you to take action, improve performance, and grow. Think of the adrenaline rush before an exciting challenge.
  • Distress (Bad Stress): The chronic, draining stress that leads to anxiety, exhaustion, and health problems.

 

Robert Sapolsky, a leading neuroscientist, emphasizes that it’s not stress itself but how long it sticks around that causes damage.

 


 

💡 II. The Science of Stress: What Happens in Your Body & Brain

 

The Fight-or-Flight Response

 

Stress triggers cortisol and adrenaline, prepping you for action. Your:

✅ Heart rate skyrockets
✅ Breathing speeds up
✅ Blood sugar spikes for quick energy

 

This is great for escaping an actual predator—but not for handling daily emails, work deadlines, or existential dread at 3 AM.

 

Stress and the Brain: What Robert Sapolsky & Andrew Huberman Teach Us

 

  • Amygdala (Fear Center): Becomes overactive, making you more anxious.
  • Prefrontal Cortex (Decision-Making): Shrinks with chronic stress, making clear thinking harder.
  • Hippocampus (Memory & Learning): Weakens, causing forgetfulness and brain fog.

 

Andrew Huberman explains that stress dysregulates our autonomic nervous system, keeping us in “high alert mode” even when there’s no real threat.

 

Stress & Aging: What Telomeres Reveal

 

Elizabeth Blackburn, a Nobel-winning scientist, discovered that chronic stress shortens telomeres—the protective caps on DNA. Think of telomeres like the plastic tips on shoelaces: when they wear down, your cells age faster. This means stress literally accelerates aging.

 


 

🔥 III. The Hidden Costs of Chronic Stress

 

Gabor Maté: How Stress Triggers Disease

 

Physician Gabor Maté has linked chronic stress to:

❌ Autoimmune disorders
❌ Cancer
❌ Chronic pain
❌ Anxiety & depression

 

Maté argues that it’s not just stress, but suppressed emotions that trigger disease. Many high-achievers push through stress, believing it makes them resilient—until their body forces them to stop.

 

Allostatic Load: The Accumulated Burden of Stress

 

Bruce McEwen describes stress as a “cumulative load.” Like a credit card, you can charge small amounts of stress daily, but over time, the interest piles up. Eventually, your body demands repayment—often in the form of illness or burnout.

 


 

🚀 IV. When Stress Helps You: The Power of Eustress

 

The Upside of Stress: Kelly McGonigal’s Research

 

What if stress itself isn’t the problem, but how we think about it?

 

In The Upside of Stress, Kelly McGonigal found that when people view stress as a challenge rather than a threat, they experience fewer negative health effects—even with high stress levels.

 

Her research suggests:

 

✅ Reframing stress as helpful makes it less harmful.
✅ People who see stress as a tool have better health and longevity.
✅ Shifting mindset can turn anxiety into excitement.

 

Steven Kotler & Flow: Turning Stress into Peak Performance

 

Stress isn’t just a burden—it’s a gateway to peak performance.

 

Steven Kotler explains that mild stress triggers flow states, the ultra-productive mode where time slows, focus sharpens, and creativity spikes.

 

Think of elite athletes or musicians in “the zone”—that’s stress working for them, not against them.

 


 

🛠️ V. How to Manage & Transform Stress into Strength

 

1. Mindfulness & MBSR (Jon Kabat-Zinn’s Method)

 

  • Mindfulness-Based Stress Reduction (MBSR) is clinically proven to lower cortisol levels.
  • Just 10 minutes of mindfulness daily can rewire your stress response.

 

2. Breathwork & the Nervous System (Andrew Huberman’s Techniques)

 

  • Physiological Sigh (Two quick inhales, slow exhale): Instantly calms the nervous system.
  • Box Breathing (4-4-4-4 count): Used by Navy SEALs to stay cool under pressure.

 

3. Sleep & Recovery: Why It’s Non-Negotiable

 

  • Sleep is nature’s reset button for stress.
  • Lack of deep sleep = higher cortisol + more stress.

 

4. Social Connection: The Stress Buffer

 

  • Loneliness increases stress-related diseases by 30-40%.
  • Spending time with loved ones lowers stress hormones and boosts resilience.

 


 

🔑 VI. Key Takeaways & Next Steps

 

Not all stress is bad—your mindset matters.
Reframing stress as a challenge makes it less harmful.
Use science-backed techniques like breathwork, mindfulness, and sleep optimization.

 

📌 Take Action Now:

 

🚀 Try a 2-minute physiological sigh to reset your stress levels.
🚀 Reframe one stressful situation today as a challenge instead of a threat.
🚀 Prioritize 7-9 hours of deep sleep this week.
