139: HRV Biofeedback & Stress Resiliency with Hanu Health

Apr 4, 2022 | Season 3


Dr. Jay Wiles is back on the podcast this week! We had an incredible conversation with him all about heart rate variability in 2021 and wanted to take a deeper dive into the nuances of HRV and to learn more about Hanu Health. In this episode, he provides insight into what a “low” HRV really means, the role of genetics, and how combining breathwork with biofeedback is game changer for supporting our nervous systems. He also shares why the Hanu Health device (coming soon!) will be revolutionary in the biohacking and stress resiliency field.
