Data-Driven Health
Most of us want to be healthier — move more, sleep better, reduce stress — but wanting isn’t the same as doing. That’s where wearables come in. Whether it’s a smart watch, fitness tracker or ring, data-driven feedback can supercharge your ability to create and stick with healthy habits.
Technology is transforming how we understand and manage our health. Tracking key health indicators in real time—provides insights that were once only possible in a clinical setting.
Here are some insights that can be tracked:
Resting Heart Rate (RHR)
Your RHR reflects how efficiently your heart is working.
Low RHR: Often a sign of good cardiovascular fitness.
High RHR (consistently over 80 bpm): May indicate poor fitness, high stress, dehydration, overtraining, or early signs of illness. It’s worth tracking trends over time.
Heart Rate Variability (HRV)
HRV can be an indicator of your nervous system balance, recovery and stress. It measures the variation in time between each heartbeat.
Higher HRV = better resilience and recovery
Lower HRV = less cardiovascular fitness or body is under stress or not recovering well.
Activity levels
Low steps per day and activity minutes are strongly linked with multiple chronic conditions and reduce healthspan.
VO2 Max
This measures how much oxygen your body can use during exercise. It’s one of the strongest predictors of longevity and aerobic fitness. Improving your VO2 max can be a game-changer for long-term health.
The most accurate VO2 max measurements are done in labs, but for most people who aren’t elite athletes, tracking VO2 trends with wearables offers a practical and valuable way to monitor cardiovascular fitness over time. It’s this trend data that’s most valuable.
Wearables such as Garmins, Apple watches and Fitbits measure estimated VO2 max levels.
Sitting Time
Even if you’re smashing your daily step count or hitting the gym, sitting for long periods can still harm your health. Prolonged sedentary time is linked to increased risk of heart disease, type 2 diabetes, some cancers, and even premature death—independent of how much exercise you do.
Tracking your sitting time (also known as sedentary time) using wearables can help raise awareness and prompt simple shifts in your day—like standing up every 30 minutes, walking during calls, or using a sit-stand desk.
Sleep Patterns and Quality
Many wearables track sleep duration, consistency and stages (light, deep, REM). Poor sleep — especially if prolonged — impacts immunity, cognition and metabolic health.
Why Wearables Help Habits Stick
Instant Feedback: Small wins (like hitting your steps goal) release a brain chemical - dopamine, reinforcing the behaviour.
Goal Setting Made Easy: Daily and weekly targets help break big goals into bite-sized habits.
Consistency Counts: Reminders and nudges help make healthy behaviours part of your routine.
Pattern Recognition: Over time, you can identify what supports or sabotages your progress (like how poor sleep affects your motivation to exercise).
Gamification: Badges, streaks and social features can boost motivation, especially if you’re a competitive type.
Generic goals fail fast. Tangible trackable goals like closing your activity rings or improving your sleep are easier to commit to and more satisfying to complete.
