BenGreenfieldLife.com/hanupodcast Hanu Health is a venture-backed health technology company at the intersection of HRV, breathwork, stress resiliency, and biofeedback. They have designed what they call "the most sophisticated and accurate wearable for detecting changes in human stress response, using continuous HRV monitoring as its primary metric". Hanu promises to be a non-invasive and easy-to-use hardware/software system that acts as a stress coach whenever you are wearing it. It uses gentle vibrations to alert you as to when you might be experiencing signs of stress and provides in-the-moment exercises and training to help you build stress resiliency. This close-looped feedback system means that Hanu is continuously monitoring your stress response and is always there to provide you with valuable means to better attend to stress in the moment.  Dr. Jay Wiles, my guest on today's show, is no stranger to the Ben Greenfield Life podcast, as you've heard him and Ben cohost the Q&A episodes since 2019. What you may not know about Dr. Wiles is that he is the co-founder and Chief Scientific Officer of Hanu Health.

A clinical health and performance psychologist with board certification in heart rate variability biofeedback and peripheral biofeedback, he works as a leading consultant in psychophysiology to health influencers, professional athletes and teams, executives, and high performers. Jay has pioneered new and innovative means of using heart rate variability (HRV) and respiratory training as both diagnostic indicators of the dynamic nature of the human stress response, alongside therapeutic tools for regulating and conditioning this response for peak human performance. Dr. Wiles has an extensive history of working with top-performing athletes in the PGA, LPGA, MLS, MLB, ATP, and WTA.
