How You’re Damaging Your Nerves And What You Can Do About It.

Full show notes: www.bengreenfieldlife.com/skinrepair 

In this episode with Justin Gardner, you'll explore the science behind hypochlorous acid (HOCl), a compound your white blood cells already make to kill pathogens, repair tissue, and control inflammation. You'll discover why it can be 100x more effective than bleach without driving bacterial resistance, how it outperforms hydrogen peroxide and Neosporin without stinging or damaging healthy tissue, and why formulation and pH determine whether a product actually works. From cuts and acne to post-procedure recovery and eczema, this is one of the most versatile and overlooked tools in skin health.

Justin Gardner is a medical technology entrepreneur with over 20 years of experience bringing regenerative and clinical innovations to market. He licensed and scaled hypochlorous acid-based solutions into the consumer space through Active Skin Repair, a line of medical-grade HOCl formulations cleared by the FDA for use on open skin and verified to EWG's highest standards.

Full Show Notes:https://bengreenfieldlife.com/rootsofhealth 

In this special "Best Of" episode, you'll explore some of my most impactful conversations on what actually builds long-term roots of health. If you're dealing with low energy, hormonal issues, chronic inflammation, or just a nagging sense that something's off despite doing all the right things, this episode gives you a clear roadmap.

You'll hear from Daniel Baird on why the synthetic fabric in your underwear may be quietly disrupting your hormones and why microplastics are becoming one of the biggest threats to male reproductive health, while Katy Bowman makes the case that your chair and mattress are doing more damage than you think. Justin Roethlingshoefer shares how a near-death diagnosis at 32 completely rewired his approach to health data and recovery. Dr. Cate Shanahan breaks down how the oils in your kitchen are being incorporated into your cell membranes. Julie Gibson Clark shows how she rebuilt her health from scratch in her 40s. And James Pieratt closes with a deep dive into what Spartan warriors actually trained like, and why it still holds up as one of the most complete blueprints for human performance ever devised.

Whether you listen start to finish or jump to the section that speaks to you most, you'll find something in here that changes the way you think about your health.

The Dirty Truth About Your UNDERWEAR, Cooking Oil & Chair? Microplastics, Hormones, Seed Oils, HRV & More: Best Of Roots Of Health

Full Show Notes: https://bengreenfieldlife.com/sisson2026 

In this episode with Mark Sisson, you'll discover why VO2 Max may be overrated as the gold standard for longevity, and why chasing it cost Mark 32 pounds of muscle and the real-world function that actually matters. You'll explore his "Old Man Olympics" framework: a decathlete's approach to fitness at 72, spanning strength, speed, balance, and endurance. You'll also get his take on cold plunging, alcohol, biohacking, AI, and find out why foot health may be the single most overlooked lever in your longevity toolkit, from bunions to glute activation to big toe function.

Mark Sisson ignited the ancestral health movement with Mark's Daily Apple and The Primal Blueprint, popularized keto and intermittent fasting with The Keto Reset Diet and Two Meals a Day, and sold Primal Kitchen to Kraft Heinz for $200M. He now runs Peluva, a toe-separated shoe company built around restoring foot strength and healthy gait, and is the author of Born to Walk.
