Heart Rate Variability (HRV) has become one of the most popular metrics in health, performance, recovery, and breathwork — but it’s also one of the most misunderstood. In this video, I break down the biggest mistakes people make when interpreting HRV, why higher HRV is not always better, and how to think about HRV in a way that actually aligns with human physiology and scientific evidence. HRV is not a score to chase. It’s a physiological signal that only becomes meaningful when interpreted in context, across time, and within the individual. In this video, you’ll learn: -What HRV (Heart Rate Variability) actually measures

  • Why HRV is not just a parasympathetic marker

  • The difference between time-domain and frequency-domain HRV metrics

  • Why comparing HRV numbers between people is meaningless

  • How breathwork increases HRV acutely (and why that doesn’t guarantee long-term adaptation)

  • The role of respiratory sinus arrhythmia, baroreflexes, and mechanical effects of breathing

  • Why trends, variance, and stability matter more than single daily values

  • How narrowing HRV variance often reflects improved stress resilience and nervous system regulation

  • Real-world examples of HRV changes during overtraining, recovery, sleep disruption, alcohol, and lifestyle stress

We also explore why acute increases in HRV from slow breathing (5–6 breaths per minute) don’t automatically mean long-term improvements in autonomic balance — and why many breathwork studies show nuanced changes in low-frequency and very-low-frequency domains, rather than simple parasympathetic dominance.
