From Step Counters to Health Guardians: The Wearable Revolution

Remember when wearable tech was just about counting your steps? The early days of Fitbit, circa 2009, were all about gamifying movement, encouraging people to hit that magic 10,000-step number. Fast forward to today, and the devices on our wrists are starting to look more like full-fledged medical monitors than fitness accessories.

The global wearable tech market is booming. Valued at $84 billion in 2024, it’s projected to grow to over $186 billion by 2030. That’s not just because people want to track their workouts, it’s because wearables are increasingly being seen as tools for continuous health monitoring. Apple Watches can now take ECG readings, Garmin devices measure stress and oxygen saturation, and companies like Whoop and Oura are tracking sleep in ways that were once reserved for lab environments.

More than 30% of Americans now own some kind of wearable fitness tracker or smartwatch. That number jumps among younger demographics, with over 40% of adults aged 18–34 reporting regular use. But the wearable trend isn’t just about exercise. What we’re seeing is a quiet but powerful shift in how people engage with their own health, before they ever step into a doctor’s office.

New startups and medical device companies are pushing the category even further. Abbott has developed a non-invasive continuous glucose monitor (CGM) for general wellness use. Nix is bringing real-time hydration monitoring to athletes. And companies like Movano and Biobeat are aiming to offer blood pressure, temperature, and respiratory data in sleek, consumer-friendly devices.

This expansion of functionality comes with a growing question: are we inching closer to a future where wearables become a core part of preventive medicine? The implications are massive. Doctors could one day prescribe smartwatches to monitor chronic conditions, catch early signs of illness, or personalize treatment in real time. Health insurers could offer discounts for users who agree to share data. Employers already do.

But there’s another side to this. As wearable devices collect more sensitive health data, privacy and regulation become critical issues. Who owns the data from your Oura ring? How is it stored? Who can access it, and for what purpose? HIPAA doesn’t always apply when health data is collected by consumer devices instead of medical institutions. And while companies promise security, breaches and misuse are inevitable risks.

Still, the benefits are hard to ignore. The real value of wearables might not be in what they measure today, but in the longitudinal data they collect over time. Imagine the power of having ten years of your vitals charted in detail, ready for your doctor to analyze during a checkup. That’s not science fiction, it’s right around the corner.

As the line between consumer tech and healthcare blurs, wearables may become the front line of personal health management. The step counters of yesterday are evolving into the health guardians of tomorrow.

Spotlight: Arca

Arca is redefining the carbon removal game by using mining waste to naturally absorb CO₂ from the atmosphere. The startup leverages a process called carbon mineralization, which accelerates how certain rocks trap carbon, transforming industrial leftovers into climate assets. Based in Canada, Arca is already working with major mining partners in North America and Australia, turning tailings into tools for planetary repair. With climate pressure mounting, this is one company that’s quite literally turning waste into future-proof wealth.

Wild Card

The Twins-Red Sox series this weekend is a perfect early-season litmus test. If Minnesota’s pitching can hold up against Boston’s aggressive lineup at Fenway, it will prove they’re more than just AL Central contenders. Look for Joe Ryan or Bailey Ober to steal the spotlight. If either can silence that park, the Twins might be onto something bigger than expected. I’ll be in Boston this weekend and at the game on Friday to see it unfold.
