From step counts to sleep stages, heart rate variability to blood sugar spikes, wearable devices are giving us a front-row seat to what’s happening inside our bodies. Strapped to wrists, slipped onto fingers or wrapped around our biceps, wearables like the Oura Ring or Whoop strap promise insight in the quest for better health. But numbers alone don’t tell the whole story. At Vail Health, wellness experts blend wearable data with nuanced human care to create a fuller picture of well-being.

Healthspan vs. Lifespan: A Wellness Approach

Unlike lifespan, which measures how long you live, healthspan focuses on the quality of life — helping people remain active, strong and mentally sharp as they age. At Vail Health, specialists in exercise physiology, nutrition, functional medicine and behavioral health encourage a customized approach for each person’s healthspan journey. Setting a baseline — through blood work, fitness testing, and metabolic and movement screenings — helps identify issues and tailor a plan.

Another essential component? Wearables. Data from straps, rings and monitors can connect day-to-day choices with long-term goals.

“We believe in a multifaceted approach with exercise, nutrition and functional medicine all working together,” says Josiah Middaugh, Vail Health’s lead exercise physiologist. “Wearables give us objective data and valuable insights into training load, recovery, exercise intensity and sleep metrics.”

That data can reveal how sleep, stress or alcohol affect heart rate variability, or how specific foods impact blood sugar in real time. Custom heart-rate zones also help users fine-tune exercise intensity.

Still, Middaugh stresses that the numbers are only part of the picture. “Perception of effort, fatigue and recovery is just as important,” he says. “The technology is there to help us learn more about our bodies — to help us tune in, not tune out.”

When Wearables Provide Insight

For many, wearables like the Oura Ring, Whoop strap, Apple Watch or continuous glucose monitor offer tangible feedback about how daily choices affect the body.

Dr. Eliza Klearman, a functional medicine provider at Vail Health, says wearables are especially useful when people “tag” lifestyle choices — logging alcohol, stress or travel — to see patterns.

“Logging things like food, alcohol intake, travel, stress or illness, so they can truly see how lifestyle choices affect biometrics like sleep, recovery and readiness — that’s when the data becomes deeply personalized and actionable,” Klearman says.

Christine Pierangeli, a nutrition therapist at Vail Health, says wearables can reveal how food and energy needs line up.

“I had a client who was constantly tired in his workouts,” she says. “When we looked at his Oura data, we saw he was under-eating for his daily burn. Adjusting his intake made a huge difference in his energy.”

Wearables can uncover subtle trends — like underfueling or early signs of overtraining — and help people connect the dots between choices and outcomes. Their real power lies in making those insights actionable.

The Slippery Slope of Too Much Data

While wearables are powerful tools, experts say they aren’t infallible — or right for everyone. Without guidance, numbers can sometimes create more stress than clarity.

“People can get so fixated on a sleep score that they actually make their sleep worse,” Klearman says. “If the data starts creating anxiety, that’s when we encourage stepping back and focusing on how you feel — your mood, energy and focus — rather than chasing a number.”

Pierangeli agrees. “There’s a time and place to be data-free. One client went on his honeymoon and left his Oura Ring at home, which I thought was brilliant. Sometimes you just need to live without metrics.”

Middaugh, a professional triathlete and XTERRA World Champion, has been using wearables since the 1990s. Yet he’s firm that no single metric should be taken in isolation.

“Not everything that counts can be counted, and not everything that can be counted counts,” he says.

Finding the Balance

Used with intention, wearables can help practitioners spot dips in sleep, readiness or HRV. “It gives us a chance to share strategies and offer support,” Pierangeli says.

But across the board, practitioners stress that technology should enhance, not override, intuition.

“Wearables can gamify exercise and promote adherence,” Middaugh says. “But the goal is to use them as one piece of the puzzle, not the entire picture.”

Wearables can’t replace wisdom, but they can spark insight. Used with curiosity and balance, they remind us to move more, rest deeper and pay attention to what our bodies are telling us. As the Vail Health team emphasizes, the numbers are there to guide — not define — us.
