Heart Rate Variability: The Nervous System Has Something to Say

Heart rate variability — or HRV — has become one of the most talked-about metrics in wellness spaces, yet few people fully understand what it measures or how to interpret it meaningfully. In this episode, we unpack what HRV actually is, why it matters, and how yoga practices may influence the nervous system flexibility it reflects over time.We explore the relationship between HRV, the autonomic nervous system, vagal tone, breath, stress, recovery, and nervous system resilience — all through the lens of yoga teaching and embodied practice.What You’ll Learn- What HRV actually measures — and why variation in the heart is healthy- How the sympathetic and parasympathetic nervous systems influence HRV- Why the vagus nerve and breath play such a central role in nervous system regulation- Why your HRV baseline is deeply individual and shaped by many factors- How yoga, pranayama, meditation, and recovery practices may support HRV over time- Why trends matter more than single readings when tracking HRV- How this framework can deepen the way yoga teachers understand sequencing, breathwork, and nervous system supportThis is the seventh post in a foundational series on nervous system literacy for yoga teachers.If this lens resonates with your teaching, I invite you to subscribe to Nervous System Literacy for Yoga Teachers on Substack.
