Ep 62 | Why Are We Scared of The Sun? In Defense of Sunlight & Naked Cartwheels in The Sun | Nuanced Advice on Sun Exposure & Sun Protection

Julie and Karinda are back from the NHAA Herbal Medicine Summit to tackle one of the most controversial, misunderstood topics in functional health: sunlight. Inspired by the hot-off-the-press book, In Defense of Sunlight by Rowan Jacobsen, they look past the rigid “slip, slop, slap” messaging to explore why sun avoidance might actually be driving our chronic disease epidemic. From the evolutionary biology of pale skin and blue eyes, to how your skin microbiome builds UV-resistant, cancer-fighting bacteria when exposed to natural light, this episode is a masterclass in circadian nuance. Ready to take this deeper and build your own strategic light routine? Join us for our upcoming live masterclass, Returning to Our Natural Rhythm: How to Use Sunlight and Darkness for Whole Body Health and Healing, on Thursday, July 2nd at 6:30 PM AEST. We’ll show you how to assess your skin type, build a solar callus, and optimise your circadian biology from sunrise to bedtime. 👉 Click here to claim your spot live or get the replay! ~ MENTIONED IN THIS EP: Book: In Defense of Sunlight: The Surprising Science of Sun Exposure by Rowan Jacobson (2026) Nature Book Review Study: Cell (2021) Study: Nature (2023) — Skin microbiome of lifeguards Dr. Richard Weller The Nuanced Naturopaths Episode: Making Vitamin D vs. Taking Vitamin D The Nuanced Naturopaths with Rebecca Edwards on Vaginal & Oral Microbiome, and on Probiotic Myth Busting ~ TIMESTAMPS 00:00 NHAA Summit Debrief & Overcoming Imposter Syndrome 07:00 How to Get Speaking Opportunities as a New Grad (The Power of Saying Yes) 13:36 Nature Book Review: “Naked Cartwheels in the Sun” & Rowan Jacobson’s Book 19:17 Growing Up in the '70s vs. Modern Sun Phobia 23:34 The Truth About Melanoma: Why It Occurs in Areas Never Exposed to Light 27:00 Why Vitamin D Supplements Can't Replace the 50+ Metabolites Produced by UVB 31:52 The Swedish Study: How Sun Exposure Reduces All-Cause Mortality 33:24 Evolutionary Biology: Pale Skin, Blue Eyes, and Southern Hemisphere Sun 38:55 Urocanic Acid & The Eye-Skin Mismatch (Why Sunglasses Block Skin Protection) 47:53 The Skin Microbiome: How Lifeguards Develop UV-Resistant, Cancer-Fighting Bacteria 53:45 The Skin-Brain-Gonad Axis: Sunlight on Genitals & Sex Hormones (The 2021 Cell Study) 58:16 Masterclass Invite: “Returning to Our Natural Rhythm” (July 2nd) 59:36 The Mind-Blowing Cardiovascular Stat: Sun Abstinence vs. Heart Disease 01:01:55 Why Your Doctor Still Prescribes “Slip, Slop, Slap” (Clinical Guidelines Lag) 01:05:37 Taking Your Medical Power Back & Self-Led Education ~ Reach out to the Nuanced Naturopaths⁠⁠⁠ ⁠here⁠⁠⁠⁠!
