Jonny Miller on Nervous System Mastery, Grief, and Why High Performers Can't Afford to Stay Stuck in Their Heads 

Your nervous system is running every decision, relationship, and reaction in your life, and you won't notice how much it's costing you until something breaks. This episode gives you the exact framework for building real nervous system mastery instead of running on autopilot until it fails.

Host Dave Asprey sits down with Jonny Miller, host of the Inner Frontier Podcast and founder of Nervous System Mastery, who has taught more than 1,000 people how to build the skills of interoception, self-regulation, and emotional fluidity. A former Silicon Valley founder turned nervous system expert, Jonny brings a rare mix of rational, data-driven thinking and deep somatic work to a field most high performers avoid entirely. 

They break down why interoception, self-regulation, and emotional fluidity are the three learnable skills behind every major shift in performance, relationships, and decision-making, and why most high achievers have spent their whole lives disconnected from what's happening below the neck. Jonny introduces the half-life of reactivity, his framework for measuring how quickly someone can move from triggered back to calm, and explains how free diving became his gateway into surrender, breath work, and pressure equalization as a form of high-stakes meditation. Dave shares his own parallel journey through nervous system work, including lessons from running 40 Years of Zen and a costly business betrayal that reshaped how he reads people. Dave and Jonny also open up about grief, including Jonny's experience losing his fiancée and later his mother, and how community and co-regulation shape how fast someone actually heals.
