Most people stay locked in a constant sympathetic state without realizing it, which drains focus, sleep quality, emotional balance, and long-term resilience. This episode gives you a science backed path to retrain your nervous system, improve heart rate variability, and shift out of stress on command using focused ultrasound technology that targets the vagus nerve. Watch this episode on YouTube for the full video experience: https://www.youtube.com/@DaveAspreyBPR Host Dave Asprey talks with Jon Hacker, CEO of NeurGear and creator of ZenBud. Jon is a biomedical engineer who has dedicated his career to bridging neuroscience and daily wellness. His work includes peer reviewed clinical research on anxiety, PTSD, autonomic regulation, and non invasive vagus nerve stimulation. He is one of the first innovators to bring focused ultrasound out of the lab and into a practical wearable designed to help people regulate state, build resilience, and create more conscious control over their biology. In
