Dr. M's Women and Children First Podcast

Welcome back to Dr. M’s Women and Children First. Today, we are joined by one of the leading voices in the world of vagus nerve health, functional medicine, and autonomic nervous system regulation, Dr. Navaz Habib. Dr. Habib is a chiropractor, educator, international speaker, and author of the bestselling books *Activate Your Vagus Nerve* and *Upgrade Your Vagus Nerve*. His work has helped bring the science of the vagus nerve from the research world into practical clinical medicine, helping providers and patients better understand the powerful connection between the brain, immune system, gut, metabolism, and overall health. On today's episode, we take a pediatric lens to this fascinating topic. We explore how vagal tone influences inflammation, stress resilience, digestion, sleep, emotional regulation, and neurodevelopment. We discuss what happens when the autonomic nervous system becomes dysregulated, how chronic stress can shape a child's physiology, and why the vagus nerve may be one of the most important communication highways in the body. We'll also dive into practical strategies that families and clinicians can use to support vagal function, including breathing techniques, movement, nutrition, social connection, sleep, and other evidence-informed interventions that can help children build greater resilience in an increasingly stressful world. If you've ever wondered how the nervous system intersects with immune health, behavior, gut function, and chronic disease risk, this conversation is for you. Please join me in welcoming Dr. Navaz Habib. Dr. M

Dr. Carrie Jones, ND, MPH Hormone Literacy Welcome back to Dr. M’s Women and Children First, where we step back from symptoms and ask a more interesting question: how does the female hormonal system actually develop, adapt, and sometimes struggle across a lifetime? Today’s conversation spans that entire arc, from early life, to puberty, to fertility and more with someone who has spent more than two decades living inside that complexity. My guest is Dr. Carrie Jones, an internationally recognized speaker, consultant, author, and educator in women’s health and hormones. Many know her as the “Queen of Hormones,” but what really defines her work is not titles, it’s her ability to translate very complex endocrinology into biology that actually makes sense. Dr. Jones is a naturopathic physician who completed a two-year residency focused on women’s health and endocrinology. She holds a Master of Public Health, was one of the very first clinicians to become board certified through the American Board of Naturopathic Endocrinology, and is a Menopause Society Certified Practitioner. She helped shape how an entire generation of clinicians think about hormone testing and interpretation as the first Medical Director at Precision Analytical, the creators of the DUTCH test, and later as the first Head of Medical Education at Rupa Health. She’s served on Under Armour’s Human Performance Council, consulted for multiple women’s health and laboratory companies, and now serves as Chief Medical Officer at NuEthix Formulations. Many of you will recognize her voice from the Root Cause Medicine Podcast, which reached more than ten million downloads, and she now hosts her own show, Hello, Hormones, where she continues to explore how hormones shape mood, metabolism, immunity, fertility, and aging. But what makes today’s conversation especially important is this: we’re not just talking about menopause, or cycles, or lab values. We’re asking a bigger question. How have female hormones changed across generations? How early life nutrition, stress, environment, and metabolic health shape the hormonal story from birth forward. And how modern exposures, from ultra-processed diets to endocrine-disrupting chemicals, may be quietly rewriting the biology of women long before symptoms ever appear. This is a systems-level conversation about development, resilience, and adaptation, and few people are better equipped to guide us through it than Dr. Carrie Jones.

The Year in Review - 2025 Articles and Points of Interest: 1) Microplastics in the Brain - From Science Advances: "Human health is being threatened by environmental microplastic (MP) pollution. MPs were detected in the bloodstream and multiple tissues of humans, disrupting the regular physiological processes of organs. Nanoscale plastics can breach the blood-brain barrier, leading to neurotoxic effects. How MPs cause brain functional irregularities remains unclear. This work uses high-depth imaging techniques to investigate the MPs within the brain in vivo. We show that circulating MPs are phagocytosed and lead these cells to obstruction in the capillaries of the brain cortex. These blockages as thrombus formation cause reduced blood flow and neurological abnormalities in mice. Our data reveal a mechanism by which MPs disrupt tissue function indirectly through regulation of cell obstruction and interference with local blood circulation, rather than direct tissue penetration. This revelation offers a lens through which to comprehend the toxicological implications of MPs that invade the bloodstream." (Huang et. al. 2025) 2) From Nature Medicine: "Brain insulin responsiveness is linked to long-term weight gain and unhealthy body fat distribution. Here we show that short-term overeating with calorie-rich sweet and fatty foods triggers liver fat accumulation and disrupted brain insulin action that outlasted the time-frame of its consumption in healthy weight men. Hence, brain response to insulin can adapt to short-term changes in diet before weight gain and may facilitate the development of obesity and associated diseases." (Pullman et. al. 2025).... Dr. M
