On today's podcast, we dive deep into the fascinating connection between the vagus nerve and the immune system, exploring how these two critical systems communicate bidirectionally. We examine the role of immune cells throughout the body and discuss recent advances in bioelectronic medicine. This episode offers a fresh perspective on nervous system regulation and its impact on overall health, especially concerning the gut brain axis.
Dr. Navaz Habib, aka "The Vagus Nerve Doc," is a best-selling author and host of ‘The Health Upgrade Podcast’. After using functional medicine to overcome his own health challenges, Dr. Habib built Health Upgraded, an online health program guiding parents and professionals to enhance their health by unlocking the healing power of the Vagus nerve to reduce the effects of stress and inflammation.
JP Errico has spent more than two decades at the intersection of science, innovation, and entrepreneurship, with a focus on neuroimmunology and medical technology. Over the course of his career, he has been awarded dozens of patents, developed groundbreaking medical devices, and helped bring new health technologies from concept to market, including non-invasive Vagus Nerve Stimulation.
