Dr. Torkil Færø is a Norwegian physician, wearable-data researcher, and author of The Pulse Cure — now back with a new book, The Sun Cure, released today in Norway. After noticing that heart rate variability could double simply from sun exposure, Torkil spent years digging into the research and found that sunlight touches nearly every major disease doctors treat today, from heart disease to cancer to chronic inflammation.In this conversation, Torkil breaks down the different wavelengths of sunlight and what each one does in the body, why the UK Biobank and Melanoma in Southern Sweden studies suggest low sun exposure carries mortality risk comparable to smoking, how morning light exposure sets the circadian clock and downstream hormone release, why sitting near a window changes cognitive performance and hospital recovery times, the surprising research showing sunscreen doesn't prevent skin cancer, why sunglasses may be blocking a key signal your body uses to prepare for UV exposure, and how he restructured his own life — including driving a motorhome from Oslo to southern Spain — around getting more daylight.Builders & Doers is produced by Horizon Search.Find Torkil: Instagram @dr.torkilBook: The Sun Cure (Norwegian, English translation forthcoming) / The Pulse Cure (available now) https://northernstories.no/books/231-torkil-faero-the-sun-cureFind out how much revenue your company is leaking: take the 4-minute Revenue Leak Scorecard → https://horizonsearch.com/scorecard?utm_source=youtube&utm_medium=descriptionWork with us: https://horizonsearch.com/revenue-architectureTimestamps:0:00 Intro — from wearable data to writing a book on sunlight1:16 The Sun Cure: why sunlight affects nearly 100 diseases3:16 UVA, UVB, infrared — breaking down the spectrum5:37 Is too little sunlight as dangerous as smoking?7:23 Controlling for confounders: the UK Biobank study (400,000+ people)10:12 Morning light, the eyes, and setting the circadian clock12:20 Lux explained: outside vs. office vs. living room light levels15:40 Skin aging vs. living longer — the tradeoff no one talks about17:35 Is there an ideal daily ”dose” of sunlight?20:08 Why sitting near a window changes performance and recovery24:47 Vitamin D supplements: helpful, or just a biomarker?27:45 Winter light, road-tripping to Spain, and rebuilding a daily routine32:01 UVB, endorphins, and blood pressure — the hormonal cascade37:09 Does sunscreen actually prevent skin cancer?
