    Ep. 606 The Vagus Nerve's Role in Stress Resilience with Dr. Navaz Habib | Menopause, Perimenopause, Nervous System
    Jun 13 2026
    I am honored to connect with Dr. Navaz Habib today. He is the Vagus Nerve Doc, a bestselling author, and host of the Health Upgrade podcast. In our discussion today, we look at what it takes to upgrade the vagus nerve, exploring how it is regulated, the role of vagal tone, and how it can be damaged with chronic stress. We examine the impact of allostatic load and dysregulation, and how midlife physiology compels us to proactively address our vagal tone. We cover the impact of acetylcholine and other neurotransmitters, and why key nutrients like choline and omega-3s are necessary for proper vagal tone, and we dive into hormetic stressors and safety, how HRV and vagal tone are assessed, and targeted strategies to enhance vagus nerve performance. Dr. Habib also discusses his Vagus Program, which provides tools to improve vagal tone. Stay tuned for this informative conversation with Dr. Habib. I look forward to inviting him back to continue the discussion. IN THIS EPISODE, YOU WILL LEARN: Dr. Habib describes the vagus nerve as the brake system of the autonomic nervous system, and explains how it connects to most major organs, working as a central communication highway What vagal tone is Dr. Habib frames allostatic load in the context of a combined stress burden How “little t” trauma influences vagus nerve function and creates stress response patterns later in life Why midlife can be a period of increased stress sensitivity and autonomic dysregulation The key biochemical drivers of vagus nerve signaling and immune regulation How diaphragmatic breathing can directly influence vagus nerve activity What HRV actually measures, and how to interpret it correctly A practical framework of small interventions to build long-term autonomic flexibility Bio: Dr. Navaz Habib Dr. Navaz Habib, aka "The Vagus Nerve Doc," is a best-selling author of 2 books - “Activate Your Vagus Nerve” and “Upgrade Your Vagus Nerve” 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 implementing his VAGUS protocol, to guide parents and professionals to enhance their health by unlocking the healing power of the Vagus nerve to reduce the effects of stress and inflammation.

    Ep. 605 "What Happens When You Stop the Pill in Midlife?" | Oral Contraceptives, Menopause, Perimenopause, Hormones
    Jun 11 2026
    Welcome to the latest Midlife Minute. Today, I’m taking a closer look at oral contraceptive use in perimenopause and menopause, exploring how oral contraceptives work, how they suppress or blunt perimenopausal and menopausal symptoms, alter hormone signaling and testing, what women may experience when they stop taking them, and why the gut microbiome is an essential part of the conversation. IN THIS EPISODE, YOU WILL LEARN: How oral contraceptives suppress certain key signaling hormones, making it difficult to assess women’s menopausal status accurately What women may experience when transitioning off oral contraceptives How long-term oral contraceptive use can alter gut microbial function and inflammatory pathways The association between long-term oral contraceptive use and nutrient depletion Why the standard reproductive hormone markers used to assess menopause (especially FSH/LH) are unreliable while on the pill How the microbiome changes that occur as women age may compound the effects of previous oral contraceptive use Helpful dietary, microbiome, and lifestyle strategies to support women navigating the post-pill transition Connect with Cynthia Thurlow Follow on X, Instagram & LinkedIn Check out Cynthia’s website.

    Jun 10 2026
    Today, I’m thrilled to connect with Rowan Jacobsen. Rowan writes about science, nature, and the world’s lesser-explored corners for publications including Harper’s, Outside, The Atlantic, Scientific American, Smithsonian, and The New York Times, among others. He is the author of nine books, has lectured at Harvard and Yale, and has appeared on CBS, NBC, and NPR. In today’s conversation, we discuss his unique and fascinating new book, In Defense of Sunlight, which explores the nuances surrounding light exposure. We look at the value of sun exposure and vitamin D, and Rowan explains why light acts as a master regulator in the body and how our modern lifestyles may be disrupting our natural biology more than we realize. We examine the effects of shift work, cortisol rhythm dysregulation, and the minimum effective dose of sunlight intensity and exposure, and Rowan breaks down how UVA and UVB wavelengths impact our physiology. We also cover the importance of nitric oxide production, and Rowan shares recommendations from his work. Stay tuned for an eye-opening conversation on why sunlight may be one of the most overlooked foundations of human health. For those who enjoy reading about science, I highly recommend Rowan’s book! IN THIS EPISODE, YOU WILL LEARN: Why so many people fear any sun exposure rather than aiming for sensible, moderate exposure How light acts as a master regulator for circadian biology Why does spending most of the day indoors with artificial lighting make it harder to maintain healthy circadian rhythms? How shift work disrupts the body’s normal repair processes How cortisol and melatonin work together as part of a coordinated daily rhythm What research shows about cloudy outdoor environments providing higher light levels than most indoor spaces The differences between how UVA and UVB exposure impact the body How ultraviolet light can trigger nitric oxide release Practical ways to support your circadian health Connect with Cynthia Thurlow Follow on X, Instagram & LinkedIn Check out Cynthia’s website.

    Ep. 601 “Why High-Functioning Women Stay Stuck” – The Nervous System Patterns Keeping You in Survival Mode with Dr. Nicole LePera
    Jun 3 2026
    I am delighted to reconnect with Dr. Nicole LePera today. Trained in clinical psychology, she is a holistic psychologist whose work explores the interconnections among the mind, body, and soul, incorporating holistic lifestyle and psychological wellness practices. She has written multiple New York Times bestselling books, most recently Reparenting the Inner Child. In today’s conversation, we unpack what the inner child really means from a clinical perspective. We explore how understanding your childhood wounds intellectually differs from truly re-parenting yourself at the nervous system level, and how perimenopause and menopause influence the way we view the world. We look at ACE scores and the biology of childhood adversity, how ACE scores measure what happened to us, but fail to measure resilience, protective factors, or the capacity for healing. We examine how reactive parents shape our nervous system, and how that shows up as hypervigilance, emotional scanning, and self-erasure, and how the fawn response can lead to chronic people-pleasing, relentless accommodation, and an inability to say no. We also cover how epigenetics and lifestyles influence behavioral patterns, critical parenting, stress addiction, gut-brain dysregulation, and the disruptive effects of vagal tone gadgets. This is truly one of those must-listen conversations! I love Dr. LePera’s grounded and practical approach to helping people work through their childhood experiences and advocate for themselves. IN THIS EPISODE, YOU WILL LEARN: How childhood wounds become stored in the nervous system rather than just the mind Why understanding your dysfunctional habits intellectually will not change the emotional patterns that drive them How perimenopause and menopause can magnify unresolved emotional patterns What ACE scores measure and what they fail to capture How reactive parenting can lead to hypervigilance and emotional scanning, even in safe environments Dr. LePera describes the fawn response and explains how children learn to over-accommodate others, suppress their own needs, and avoid conflict. How chronic stress becomes a learned response, and how stress responses can be passed across generations How chronic stress and a dysregulated nervous system can influence gut function and microbiome balance Why it’s essential to return your attention to your body in the present moment to begin healing Connect with Cynthia Thurlow Follow on X, Instagram & LinkedIn Check out Cynthia’s website.
