Episode Overview

Episode Title: Why living online is leaving us exhausted — and what actually helps
Podcast: TED Talks Daily
Speaker: Manoush Zomorodi
Date: January 5, 2026

In this engaging TED Talk, journalist Manoush Zomorodi explores the physical exhaustion many people feel in the digital age. Drawing on research and her own experiments, she unpacks how our increasingly online, sedentary lifestyles are draining our energy and contributing to global health issues. Zomorodi makes a compelling case for simple “movement breaks” as an antidote—not just for our minds, but for our bodies as well.

Key Discussion Points & Insights

1. The Hidden Toll of Living Online

• Modern Exhaustion:
  Zomorodi begins by describing the familiar feeling of finishing a day in front of a screen and being too tired to do anything but scroll on a phone or watch TV.

  “Do you ever close your laptop at the end of a long day and feel like you have just enough energy to crawl over to the couch to scroll on your phone or watch a show? Or maybe both at the same time?” (03:27)

• Screen Time Shapes Our Bodies:
  Screens have not just changed how we spend our time, they've physically reshaped us:

  • The average 19-year-old today moves as much as a 60-year-old.
  • The rate of type 2 diabetes in young people has doubled in 20 years.
  • 3 in 4 American adults have at least one chronic illness; many are preventable.

  “According to researchers at Johns Hopkins, every day the average 19 year old moves about as much as the average 60 year old.” (04:30)

  “The WHO says that this is a global problem. They predict that by the end of the decade... this lifestyle will likely lead to 500 million new cases of preventable conditions like heart disease, obesity and diabetes, costing governments $27 billion a year.” (05:18)

2. Movement Breaks: The Surprising Solution

• Research by Keith Diaz (Columbia University):

  • Diaz’s studies show that just 5 minutes of gentle movement every 30 minutes can dramatically improve health (lower blood sugar and blood pressure; reduce risk of early death).
  • Simply standing desks or daily workouts are not enough; breaking up long sedentary periods is crucial.

  “He found that just five minutes of gentle movement every 30 minutes had dramatic effects. It slashed blood sugar and blood pressure.” (06:01)
  “If you sit or stand for the majority of your waking hours, your health is in jeopardy, too.” (07:00)

• Personal Experiment:
  Zomorodi describes her participation in Diaz’s study, comparing a sedentary day to one with movement breaks. The results:

  • Glucose nearly halved
  • Blood pressure dropped by 5 points
  • Improved mood

  “My glucose was cut nearly in half, my blood pressure was down by five points, and my mood was so much better.” (08:04)

3. The Global “Body Electric” Experiment

• Scaling the Study:

  • Zomorodi and her team partnered with NPR and Columbia for a podcast and a global clinical trial, “The Body Electric.”
  • 20,000+ participants experimented with different doses of movement: 5 minutes every 30 minutes, hourly, or every 2 hours.
  • Activities varied: dancing, pacing on calls, walking the dog, taking out trash.

• Challenges and Breakthroughs:

  • Adapting to regular breaks takes “a lot of intention and a little rebellion” because modern life is built around screens and chairs.
  • Participants reported less pain, more energy, improved mood, and in some cases, weight loss.
  • Most importantly, the breaks did not hurt productivity.

  “Those first few days were so tough. It takes a lot of intention and a little rebellion to upend a world that is quite literally built around screens and chairs.” (09:13)

  “The biggest surprise to me was that the breaks did not hurt their productivity. People said they got back to their desks and they were able to focus and they felt that the work they did was actually of better quality.” (10:31)

4. The Science Behind It

• Physical Effects of Sitting:

  • Sitting kinks arteries, pools blood, and keeps muscles inactive.
  • Lack of movement prevents leg muscles from clearing fat and sugar, contributing over time to chronic diseases.
  • Poor posture from sitting compresses the diaphragm, resulting in shallow breathing and less oxygen to the brain, causing fatigue.

  “When we sit, our arteries get bent at our hips and our knees kind of like a kinked vacuum hose. Blood starts pooling in our legs and our muscles stop contracting.” (11:06)

• Screen Use and Interoception:

  • Deep engagement with screens dulls our 'interoception': our awareness of bodily needs (like moving, eating, or taking bathroom breaks).
  • We end up ignoring signals and keep “scrolling past the anxiety, scrolling past the exhaustion,” risking burnout and poor health.

5. Practical Strategies for Making a Change

• Creating “Movement Mantras”:
  Zomorodi offers practical, actionable ideas tailored for all walks of life:

  • Students: Take a lap around the quad instead of checking TikTok.
  • Remote workers: March in place during Zoom calls.
  • Parents: Walk around the soccer field or have a dance party during kitchen chores.
  • Travelers: Walk the airport concourse instead of sitting in waiting areas.

  "A mix of all these habits will keep your muscles firing and your mood steady steadier." (12:11)

• Personal Story: Dana’s Breakthrough

  • Dana, a 43-year-old woman with type 2 diabetes, combined her daily walks with movement breaks at work. Within weeks:
    • Blood pressure dropped by 40 points
    • Lower cholesterol
    • Reduced and eventually stopped insulin

  “She started fitting in movement breaks between all of her meetings and when within a couple of weeks she told me her blood pressure dropped by 40 points, her cholesterol went down, and her doctor told her she could start tapering her insulin. She's actually off all of her meds today.” (12:23)

Notable Quotes & Memorable Moments

• On why we’re exhausted:

  “Screens can mess with something called interoception… The more we focus on screens, the less we listen to the signals that our body is sending us. Your body could be begging for a break, but what do you do? You keep scrolling past the anxiety, scrolling past the exhaustion that eventually can lead to burnout.” (11:44)

• Practical encouragement:

  “Take movement breaks. And when people look at you like you’re weird, just tell them why you’re doing it because you just want to feel a little better. Get them to put down their phone and join you. Start soon. Start small. Should we start now? Yeah, let’s.” (13:14)

• Uplifting conclusion:

  “You could do the march. You could do the shuffle… If you can’t get up, feel it. You’re alive. You’re alive. Love you guys.” (13:33)

Conclusion

Manoush Zomorodi’s talk blends storytelling with actionable science and encouragement. She highlights that our digital routines are quietly sapping our energy—and our health—but that the remedy is within reach: frequent, intentional movement breaks. These simple, tiny acts don’t just protect the body; they give us back our vitality. The ultimate message: embrace a little rebellion against the stillness, and help others do the same—because, as she says, “You’re alive. You’re alive.”
