Confused about what those HRV numbers mean on your wearable device? Or if they even matter?
Learn how Resonance Theory, the same science behind musical instruments and bridge collapses, reveals why focusing only on heart rate variability (HRV) numbers misses the bigger picture of what's happening in your body.
Main Takeaways:
- Your absolute HRV number matters less than changes from your baseline
- 3 key factors affect your baseline HRV
- Daily factors like sleep, alcohol, and stress can push you away from baseline
- Looking for patterns over 2-3 weeks is more valuable than daily numbers
- Understanding your body's natural frequencies helps optimize training and recovery
