Podcast Summary: "TBD Tries... Wearables"

Podcast: What Next: TBD | Tech, power, and the future
Host: Lizzie O’Leary
Episode Date: March 1, 2026

Overview

In this episode of "What Next: TBD," host Lizzie O’Leary explores the rise, promise, and pitfalls of wearable health technology—focusing on devices like the Oura Ring, Apple Watch, and Fitbits. Together with Slate culture writer Nadira Ghaf and guests including journalist Mario Aguilar and medical professionals Dr. Sunny Cashore and Dr. Jordi Cohen, the show investigates what it’s like to live with a wearable, the accuracy and meaning of the data these devices provide, and the broader implications for public health and privacy.

Key Discussion Points & Insights

1. Personal Motivation and Experience with Wearables

• Nadira’s Story:
  • Nadira, after a difficult year marked by chronic illness and uncertainty, started using an Oura Ring for clarity about her body and health when traditional medical pathways were inconclusive.
  • She hoped the wearable would give her actionable data to improve her well-being, especially with sleep and symptom management.
  • Quote (Nadira Ghaf, 04:12):

    "I guess I just wanted some clarity about what was going on with my body at a moment where I felt like I had zero clarity."

2. What Wearables Track and Why People Care

• Popular Metrics:
  • Most wearables focus on tracking sleep quality, physical activity, heart rate, and readiness or recovery scores.
  • Industry origins trace back to simple step counters, but there’s growing ambition for deeper insights (e.g., stress and recovery metrics).
  • Quote (Mario Aguilar, 11:23):

    "The number one thing people want to track the most is, is their sleep... how well did I sleep?"

• Industry Growth:
  • The global wearables market approaches $93 billion in 2026, expected to double by 2033.

3. The Meaning and Usefulness of Wearable Data

• Readiness and Sleep Scores:
  • Nadira describes “readiness” scores as potentially arbitrary, likening them to temperature scales—relative, not absolute.
  • Quote (Nadira Ghaf, 14:29):

    "I kind of think of it like Fahrenheit versus Celsius... Sleep scores like that, 65 vs 64, 62 doesn't mean much to me. But 60 vs 70—those are differences I do feel in my body."

• Limits of Proprietary Metrics:
  • Many metrics aren't clinically recognized, combining several data streams into one (e.g., “readiness”), making them difficult for users and clinicians to interpret or act upon.

4. Wearables as Healthcare Tools: Potential and Pitfalls

• Medical Integration:
  • Apple has achieved some medical regulatory milestones (e.g., ECG features), but much of the wearable market is intentionally classified as “wellness” rather than “medical,” requiring little oversight.
  • The Oura ring—while popular—seeks a third regulatory classification for more flexible clinical claims without full FDA scrutiny.
• Doctor Perspectives:
  • Dr. Sunny Cashore continues to rely on traditional blood pressure cuffs for accuracy, seeing wearables more for trend monitoring than diagnosis (19:04).
  • Dr. Jordi Cohen cautions that the people who could benefit most from wearables (i.e., high-risk populations) are often the least likely to afford or access them (20:51).
  • Quote (Jordi Cohen, 21:01):

    "A lot of the people using these devices are the ones who are already engaged in their healthcare... My biggest concern is what's going to happen to the people left behind."

• Structural Concerns:
  • Wearables do not solve deeper issues like gaps in primary care or insurance coverage. They can sometimes be “consumer-focused bandaids” (21:19).

5. Data Privacy and Policy

• Data Black Boxes:
  • Wearables collect intimate health data, but companies’ privacy policies can be vague or legalistic.
  • Concerns arise over data sharing—with questions about how insurance companies or other third parties might use wearable-collected information.
  • Quote (Jordi Cohen, 22:35):

    "It's a black box with these companies right now."

  • Host Lizzie O’Leary, herself an autoimmune patient and cancer survivor, expresses concern over these ambiguities (23:09).

6. Real Impact on Health Outcomes

• Behavioral Benefits:
  • Some studies show that wearables can encourage positive behavior changes—more exercise, better sleep—which do lead to improved health outcomes.
  • Quote (Jordi Cohen, 23:35):

    "If whatever you're doing makes you exercise more, makes you sleep better and sleep more... these can very much and palpably improve people's health..."

7. Does It Actually Help?

• Nadira’s Verdict:
  • Ultimately, Nadira found wearables can provide helpful reinforcement and insight, but only to the extent the user engages meaningfully with the data—they can just as easily become objects of obsession, or be ignored.
  • Quote (Nadira Ghaf, 24:59):

    "A large part of what you get out of it is what you give to it... there's a fine line between obsessing... and having a healthy distanced viewpoint."

  • The emotional push from data—like being told a night’s sleep barely qualified as such—proved motivating for her (25:40):

    "...when I had that moment where I had so little sleep that it logged it as a nap, I was like, well, like, you kind of ate with that... girl, you gotta be better, right?"

Memorable Quotes & Timestamps

• Nadira Ghaf (02:43):

  "I have had a really hard year...I also knew that my sleep schedule was really feeding into my flare ups or my symptoms..."

• Lizzie O'Leary (03:12):

  "These devices do a pretty good job of tracking simple stuff...But for addressing serious health problems, the jury's still out."

• Mario Aguilar (09:23):

  "If I could fit more devices on myself, I would probably wear them—but I have reached my carrying capacity for devices."

• Mario Aguilar (13:19):

  "These interpreted metrics...are not sort of directly measured, but are rather combined with proprietary formulas."

• Jordi Cohen (21:39):

  "Wearables can feel like a consumer-focused bandaid on a medical system with more fundamental and structural problems."

• Aura Spokesperson (24:15):

  "Oura Ring is not a medical device and is not intended to diagnose, treat, cure or prevent any disease. Our goal is to provide reliable, science backed insights that support preventative relationship-based care rather than substitute for it."

Conclusion

"TBD Tries... Wearables" offers an engaging, skeptical, and personal dive into the world of health wearables, raising vital questions about trust, utility, access, and privacy. The episode blends storytelling, user experience, clinical skepticism, and policy analysis—ultimately concluding that while wearables can help some individuals understand and maybe even improve their health, they are no substitute for structural healthcare reform, accurate medical oversight, or transparent data stewardship. As Lizzie O’Leary and guests remind listeners, the profound promise of wearables is matched by equally complex and sometimes unresolved risks.
