Enhance Your Physical & Mental Resilience (HRV, Respiratory Rate, RHR)

All Episodes

In this episode, I explain how to increase your control over your nervous system — not just to manage stress, but to recalibrate your autonomic nervous system for long-term physiological resilience and adaptability. This episode goes beyond basic stress management techniques to explore how to fine-tune your nervous system, become more stress tolerant, and use your personal data to know exactly when and how to intervene. Using the three I’s framework — Investigate, Interpret and Intervene — I explain how to assess key physiological markers such as heart rate variability (HRV), respiratory rate and CO₂ tolerance. I also discuss a range of tools and strategies, ranging from free to clinical-grade, that can shift your nervous system acutely (like cold exposure or visual resets) and chronically (such as structured breathwork or exercise). This episode is for anyone looking to actively train their brain and body to improve resilience, adaptability and peak performance. Read the episode show notes at performpodcast.com.

Cardiac Cowboys

The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
