In this solo episode, Dr. Steph dives deep into the complex world of mast cell activation, histamine intolerance, and anxiety that isn’t really “just anxiety.” She explains how toxins, infections, mold, and even environmental factors like 5G and chemicals can hijack your body’s immune and nervous systems, creating a cascade of symptoms that often get mislabeled as anxiety or panic. 

Dr. Steph breaks down what mast cells actually do, how chronic inflammation starts, and why so many people feel “electric,” overstimulated, or stuck in fight-or-flight mode. Through a recent real-life case study, she reveals how everyday exposures (like an epoxy garage renovation) can re-trigger old health patterns, and she outlines how to calm the system using binders, nutrition, lymphatic support, and vagus nerve regulation. 

This episode is equal parts science and story, helping listeners connect the dots between their symptoms and their biology, and reminding them that true healing starts when we ask: Is it anxiety… or is it toxicity?
