The Arc Woman Podcast

🎙️ In this episode, I unpack what Professor Philippe Grandjean at Harvard describes as a chemical pandemic and reveal how the very system meant to shield us is missing the hidden toll women are bearing in their bodies today.
⚡Continuing from this, we journey through the world of EDCs, pesticides, flame retardants, forever chemicals, phthalates, microplastics, and synthetic textiles, exploring what the latest research reveals about their effects on fertility, endometriosis, PCOS, pregnancy outcomes, and the next generation of daughters.
🧬 Building on these findings, I dive into the molecular story: how these chemicals hijack the HPO axis, ramp up aromatase, speed up follicle loss, spark progesterone resistance, and why women shoulder a heavier chemical load than men and why that difference is crucial.
🩲 From the molecular to the everyday, we also uncover what lurks in your menstrual products, sports bras, and period underwear, and discuss what the Thinx lawsuit reveals about the gaps in protection women truly face.
📋Finally, I wrap up with the data that gives me hope: studies showing that EDC levels can drop meaningfully in just 3 days, along with practical swaps, certifications, and apps genuinely worth your attention.

🎙️ Magnesium is involved in over 600 enzymatic reactions in the body and yet roughly half of all women aren't getting enough of it. This episode covers where magnesium comes from, why modern diets and farming practices have left us depleted, and why the standard blood test your doctor orders is almost certainly missing the full picture.
🧬 We break down what magnesium actually does inside the body: how it unlocks ATP energy production, regulates the nervous system, activates vitamin D, supports estrogen clearance through the COMT enzyme, and sits at the centre of sleep, blood sugar, thyroid function, and hormonal health.
⚡ We look at the RDI and whether current nutritional science backs it up, the top food sources and what helps or blocks absorption, and a full breakdown of every supplemental form so you can choose the right magnesium for what your body actually needs.
🩺 The episode closes with magnesium's specific applications for PCOS, endometriosis, adenomyosis, PMS and PMDD, perimenopause, and Hashimoto's thyroiditis.

🎙️ In this solo episode I'm breaking down one of the most underdiagnosed, under-researched conditions in women's health a disease affecting roughly 1 in 5 women globally that takes an average of 11 years to diagnose, has no dedicated pharmaceutical treatment, and until recently could only be confirmed by removing the uterus entirely.
🔬 I get into the full pathophysiology what's actually happening in the muscle wall of your uterus, how localized hyperestrogenism drives the disease from the inside, and why your blood results can look completely normal while you're in excruciating pain.
⚡ We cover the key molecular mechanisms including aromatase overexpression, progesterone resistance, the KRAS gene mutation, the self-amplifying inflammatory feedback loop, and why the disease actively dismantles its own brakes.
🗂️ I walk you through the two distinct types of adenomyosis, the current theories on its origin, how it's now diagnosed non-invasively through MRI and transvaginal ultrasound, and what to ask your sonographer before you even book the appointment.
💊 And I cover the full treatment landscape from NSAIDs and Dienogest to the Mirena, GnRH agonists, endometrial ablation, uterine-preserving surgery, and the emerging integrative approaches.

🎙️ In this solo episode I'm reflecting on the side of medicine most women know too well and why so many of us keep falling through the cracks.
🔬 I break down medical paternalism, how it's baked into the system, and why the profession actively attracts and rewards a god complex that costs women their health, their autonomy, and their money.
⚡ We get into the patriarchy's role in medicine, from the origin of the word "hysteria" to why your physical symptoms keep getting rerouted into anxiety diagnoses and the very real economic toll that takes on women.
📋 I also share ten practical strategies for navigating the system right now, because the system isn't going to fix itself and you deserve to know how to protect yourself inside it.

She holds a Master's degree in Biomedical and Health Science, is a certified Feldenkrais practitioner, a Somatic Experiencing practitioner, and one of the first people in the world to bring nervous system and trauma healing education online reaching over 27,000 people across 90+ countries since 2012.
Irene's approach blends three powerful modalities Somatic Experiencing, the Feldenkrais Method, and developmental trauma work into a framework she calls Neuroplastic Healing Sequencing. Her flagship program SmartBody SmartMind has been formally studied in partnership with the University of Victoria, and her YouTube channel has amassed over 12 million views 🎥
She teaches that trauma isn't an event it's what happens inside the nervous system as a result. And that chronic illness, anxiety, exhaustion, and feeling perpetually stuck are often the body doing exactly what it learned to do to survive.
