Understanding HRV & Wearable Tech. Amy Stuttle is joined by Dr. Michael Twyman, a cardiologist from St. Louis, to break down heart rate variability (HRV)—one of the most misunderstood metrics in wearable health technology.
Dr. Twyman explains what HRV is and how devices like the Oura Ring measure it. He discusses the differences between time-domain and frequency-domain HRV, the accuracy of various tracking devices, and why HRV fluctuates with factors like illness, altitude, and alcohol consumption.
Dr. Twyman discusses sleep metrics, cardiovascular age estimates, and the role of Zone 2 training in fitness. Plus, they share practical insights on how to interpret HRV trends, when to trust the data, and the best tools for getting a more accurate reading.
If you're an Oura Ring user—or just someone trying to optimize health through wearable tech—this episode is packed with actionable takeaways.
