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.

Writing a book is a lot like childbirth—exhausting, and not something you rush back into the moment it’s over.

I’ve never given birth, but I have written several books—and after finishing Boundless, I wasn’t too eager to jump straight into that process again. Until recently.

There are just too many health myths wasting your time, energy, and attention—especially around supplements, cold and heat exposure, sleep, fasting, seed oils, red meat, carbohydrates, psychedelics, biohacking, and the modern obsession with living forever.

So over the coming months, I’m going to tackle these types of topics through a weekly newsletter, article, and video series, which will eventually be crafted into my next book.

If something resonates, let me know. If something falls flat, tell me. And if there’s a topic that deserves a deeper dive, point me there.

Head to https://bengreenfieldlife.com/article/newsletter-1/ for today’s article, and drop any other feedback in the comments, including topics you think I should address in the book!
