Full Show Notes: https://bengreenfieldlife.com/lnleland/ From the science behind sunlight, circadian lighting, and EMFs to practical tips on breathwork, cold exposure, and personalized nutrition, this wide-ranging conversation is packed with actionable insights. You'll learn why optimizing your external environment—light, air, water, and even mindset—is just as vital as what you eat, plus discover how environmental factors can impact everything from immune health to sleep quality. Whether you're a health enthusiast or just curious about leveling up your wellbeing, this episode delivers a blend of cutting-edge science and real-world strategies that will inspire you to rethink your daily routine. Dr. Leland Stillman is one interesting doctor and a man after my own heart - meaning he's interested in everything from how polar bears use cold thermogenesis and hibernation to enhance longevity to how your environment drastically shapes your health no matter how hard you exercise or how perfectly you eat. He became interested in natural and integrative medicine at an early age. After majoring in environmental health at Connecticut College and earning his medical doctorate from the University of Virginia School of Medicine, Dr. Stillman completed his training in internal medicine at Maine Medical Center. Board-certified in internal medicine and specializing in integrative medicine, he has a passion for doing whatever it takes to discover the root cause of his patients' medical problems through advanced laboratory testing and then addressing those imbalances with dietary or lifestyle interventions. Dr. Stillman focuses not only on the patient but on all aspects of the environment they live in. Some of Dr. Stillman's professional interests include phototherapy (photobiomodulation), nutrition, toxicology, and the immune system.

Health Myths That Waste Your Time: Supplements, Seed Oils, Cold Therapy, and More
09/1/2026 | 6min
Full Show Notes: https://bengreenfieldlife.com/article/newsletter-1 Writing a book is a lot like childbirth—exhausting, and not something you rush back into the moment it’s over. I’ve never given birth, but I have written several books—and after finishing Boundless, I wasn’t too eager to jump straight into that process again. Until recently. There are just too many health myths wasting your time, energy, and attention—especially around supplements, cold and heat exposure, sleep, fasting, seed oils, red meat, carbohydrates, psychedelics, biohacking, and the modern obsession with living forever. So over the coming months, I’m going to tackle these types of topics through a weekly newsletter, article, and video series, which will eventually be crafted into my next book. If something resonates, let me know. If something falls flat, tell me. And if there’s a topic that deserves a deeper dive, point me there. Head to https://bengreenfieldlife.com/article/newsletter-1/ for today’s article, and drop any other feedback in the comments, including topics you think I should address in the book!See omnystudio.com/listener for privacy information.

We also get real about fasting: I break down what works for high performers, how to balance longevity with peak performance, and what fasting windows actually make sense if you’re pushing your body hard.
