Know Your Physio
Hosted by Andrés Preschel · EN
Knowing your physiology, the very science that makes you who you are, is the best thing you can do to optimize your health, bolster your performance, look and feel your best, and enjoy a longer and more fulfilling lifespan. My dedication to this field derives from a selfish place born out of necessity before it became the bright, selfless passion I'm known for. It was through my health journey (mainly battling ADD and ten years of Adderall dependency plus related side effects) and love for the scientific method that I found my way. Eventually, with the right knowledge and mentorship, I stumbled upon an enhanced state of awareness between mind, body, and spirit where healthy intentions met actionable steps and lasting, positive lifestyle change. Today I call this "physiological intuition," and to me, it's a right that every human being deserves to thrive with, without having to battle themselves or pursue a degree to discover it. Every day I spend on this planet, I get to connect with world-leading experts on my podcast and learn more of the substance I wish I could have gotten my hands on earlier, for YOU to apply and enjoy total mind and body fitness, personal mastery, and self-actualization! The more you #KnowYourPhysio… Enjoy the show!

Dr. Jared Helfant: The Dangers of "Nuking" Your Mouth Bacteria | Sleep Apnea, Jaw Development & The Truth About Fluoride
Jan 701:08:20Tap to summarizeDid you know that using strong mouthwash might be destroying your blood pressure and gut health? In this episode, Andres sits down with Dr. Jared Helfant, a functional dentist who is changing the way we look at oral health. They dive deep into why the "kill 99% of bacteria" approach is outdated and how maintaining a symbiotic oral microbiome is the key to systemic health.Dr. Helfant breaks down the critical difference between nasal and mouth breathing, explaining how the latter ruins facial structure, sleep quality, and nitric oxide production. They also uncover a shocking connection between childhood ADHD diagnoses and undiagnosed sleep airway issues. From the impact of soft foods on jaw development to the debate between fluoride and nano-hydroxyapatite, this episode is packed with actionable advice to optimize your airway, sleep, and smile.Key Topics Discussed:The Functional Approach: Why dentistry should not be treated separately from the rest of the medical system.The Oral Microbiome: Why you should stop trying to "kill" all bacteria in your mouth and how to test your oral flora.Mouth vs. Nasal Breathing: The physiological disasters caused by mouth breathing, including changes in facial structure and increased cortisol.Nitric Oxide: How nasal breathing and specific foods (like beets) fuel this vital molecule for blood pressure and sexual health.The ADHD Misdiagnosis: Why 60-70% of kids diagnosed with ADHD might actually be suffering from sleep apnea and airway obstruction.Jaw Development: How breastfeeding and chewing hard foods influence the skeletal structure of the face.Sleep Apnea Solutions: Moving beyond the CPAP—using palate expanders and mandibular advancement devices to fix the root cause.Actionable Tips:Test, Don't Guess: Consider using services like Bristle to test your oral microbiome.Chew Your Food: Encourage children to chew harder foods to promote jaw expansion.Stop the Snore: If you or your partner snore, get a sleep study that looks at oxygen depletion, not just stoppages in breathing.Ditch the Nukes: Swap harsh antimicrobial mouthwashes for products that promote symbiosis.Timeline Mitopure Gummies: GET 20% Off Now! 👇https://timeline.com/andres🎯 Apply for Health Optimization Coaching🔗 https://coaching.knowyourphysio.org/video1729359042808Support the show

Brad Currier, PhD: Your Mitochondria Are Dying: How to Trigger "Cellular Recycling"
Dec 301:11:17Tap to summarizeIs your body running on broken engines?We often obsess over what we eat, but we rarely think about how our cells process that fuel. If your mitochondria (the engines of your cells) are dysfunctional, it doesn't matter how perfect your diet is—you will feel tired, you will recover slowly, and you will age faster.In this episode, we sit down with Brad Currier, a PhD in muscle physiology and scientist at Timeline, to discuss Urolithin A—the breakthrough molecule that acts as a "recycling program" for your cells. Brad reveals why natural food sources are virtually impossible to rely on (you’d need to drink 1.5 liters of juice daily), how this molecule compares to fasting for longevity, and the shocking data coming out of studies with Olympic athletes.In this episode, you will learn:The "Junkyard" Theory: Why mitochondrial dysfunction is the root cause of low energy and poor recovery.Mitophagy Explained: How to trigger the selective breakdown of "zombie" mitochondria to build fresh, healthy ones.The Pomegranate Reality Check: Why you can't eat your way to therapeutic levels of Urolithin A (and the sugar cost of trying).Fasting vs. MitoPure: The difference between "global" starvation (fasting) and "surgical" cellular repair.Olympic Secrets: How elite runners are using this specific protocol to lower perceived exertion and muscle damage.The Future of Longevity: How this impacts not just muscle, but skin, immune health, and cognitive function.Timeline Mitopure Gummies: GET 20% Off Now! 👇https://timeline.com/andres🎯 Apply for Health Optimization Coaching🔗 https://coaching.knowyourphysio.org/video1729359042808Support the show

Andrew Herr: Solving Jet Lag with Science, Inflammation, Sleep, and Smarter Travel
Oct 2401:10:32Tap to summarizeI sat down with Andrew Herr to unpack what flying really does to your body and how to fix it with simple, science-based steps. Andrew has coached fighter pilots, Navy SEALs, and busy executives, and he built a travel system that treats jet lag like a solvable problem, not a life sentence.We break down why pressure changes and lower oxygen in the cabin drive inflammation, why that brain fog and puffy feeling show up even on short hops, and how circadian rhythm, light, and meal timing fit into the picture. We get into domestic versus international travel, when you only need a “mini” protocol, and when you need the full reset. You will hear exactly how to set up sleep the first night, when to use light or block it, how to time magnesium, omega-3s, and melatonin, why small protein-first meals beat grazing on junk, and why fasting can help some people but not everyone.You will also learn how to read your own signals, why some frequent fliers think they are fine when they are not, and how to test whether something actually helps you. If you want to land clear-headed, sleep that first night, and feel like yourself again, this episode gives you a plan you can run on your very next trip.Key topicsWhy flights trigger inflammation, even on short routesCircadian rhythm basics, light timing, and sleep setupDomestic vs international playbook, what changes and whyProtein-first eating on travel days, hydration, and walking after mealsWhen fasting helps and when it backfiresBlue light blocking, battery-powered alarm clocks, and a bedroom setup after you landHow to test if a tool or supplement is working for youWhere Andrew’s timing protocol came from and how the app personalizes it without guessworkTimeline Mitopure Gummies: GET 20% Off Now! 👇https://timeline.com/andres🎯 Apply for Health Optimization Coaching🔗 https://coaching.knowyourphysio.org/video1729359042808Resources mentionedFlyKit travel protocols and refills: flykit.comBlue light blocking glasses that block high percentages at nightOmega-3s with balanced EPA and DHAMelatonin and magnesium timing for first-night sleepSupport the show

R. Blank: Understanding EMF, Its Impact on Health, and How to Protect Yourself From It.
Oct 1701:10:20Tap to summarizeI sat down with R. Blank, CEO of Shield Your Body and author of Empowered, to cut through the EMF noise with clear science and practical steps. If you’ve ever wondered what EMF actually is, what’s hype vs. real risk, and how to reduce exposure without abandoning modern tech, this conversation is for you.R. breaks down ionizing vs. non-ionizing radiation, why your cell phone is the #1 avoidable source, and the “distance × time” rule that drives smarter habits. We get tactical: building a low-EMF bedroom (no phones, battery-powered alarm clocks, low-blue rechargeable lamps), why a meter beats guesswork, when to de-energize a circuit at night, safer audio (air-tubes over AirPods), and how to configure your phone radios (airplane mode, Wi-Fi/Bluetooth off when you don’t need them). We also compare shielding products vs. Faraday gear, when apparel makes sense (travel and high-density environments), and how to think about privacy tools like Faraday wallets and laptop sleeves.If you want data-backed, low-friction ways to protect sleep, focus, and long-term health without quitting your devices, you’ll love this one. You’ll walk away with a simple rule (“stop carrying your phone in your pocket”), a bedroom checklist, and a clearer map for what to change today and what, if anything, to buy later.Timeline Mitopure Gummies: GET 20% Off Now! 👇https://timeline.com/andres🎯 Apply for Health Optimization Coaching🔗 https://coaching.knowyourphysio.org/video1729359042808Topics Covered:[00:04:11] Invisible dangers of electromagnetic fields.[00:12:02] Technology's value and abuse.[00:13:01] Personal control and empowerment.[00:17:14] EMF safer bedroom tips.[00:35:27] Cell phone radiation exposure.[00:38:08] EMF protection for cell phones.[00:42:47] Air tube headphone safety.[00:48:15] Faraday products for EMF protection.[00:54:05] EMF shielded apparel options.[01:02:22] EMF mitigation strategies for phones.[01:06:34] Phones and EMF.Support the show

How to Stop Falling for Illusions (Video Games, Dating Apps, Doom-scrolling, Weed, Alcohol)
Sep 2000:16:35Tap to summarizeYou’re surrounded by illusions that feel good now but rob you later, p*** as the illusion of intimacy, video games as the illusion of achievement, processed food as the illusion of nourishment, dating apps as the illusion of choice, doom-scrolling as the illusion of connection, weed as the illusion of peace, alcohol as the illusion of confidence, and gambling as the illusion of success. In this episode, I not only name these traps and reveal how they pacify your drive and blur your path to fulfillment. I’ll also show you what to do about them, how to recognize them for what they are, and how to take back control when they show up in your life. I’m not speaking from a pedestal. I spent a decade dependent on Adderall, fell into compulsive online habits, and learned the hard way that comfort isn’t the cure. I share my story and the science that helped me rebuild, how turning toward pain, not away from it, forged discipline, resilience, and a more meaningful life.You’ll leave with a simple lens: when a craving hits, ask, “What deep, meaningful work am I avoiding right now?” Then we use that signal to take one honest step today. If you’re ready to trade sedation for purpose and choose the difficult thing on purpose, press play.Support the show

Dave Pascoe: How I Slowed My Aging with Labs, AI & Strategy
Aug 2901:32:24Tap to summarizeI’m thrilled to bring you Dave Pascoe—a former network security architect turned longevity athlete and biohacker—whose measured approach to anti‑aging is both rigorous and refreshingly practical. We trace Dave’s journey from teenage hacker to data‑driven health optimizer, the telomere wake‑up call that shifted his mindset, and how he now tracks biological age with epigenetic testing (including the DunedinPACE “pace of aging” algorithm popularized by TrueDiagnostic). We also unpack the Rejuvenation Olympics—what the leaderboard actually measures and how to think about it without the hype. If you’ve heard buzzwords like “pace of aging” and wondered what they really mean, we translate them into plain English here. From there we get tactical: why Dave cut out ultra‑processed foods (we touch on the NOVA classification so you can spot them fast), how he reframed running and training, and why VO₂ max is one of the strongest fitness predictors of longevity. We compare sprint work vs. endurance for healthspan, dive into SHBG and testosterone (and why carbs, stress, and training load matter), and talk sleep, meditation, and the often‑ignored lymphatic system—including why movement is non‑negotiable because your lymph relies on muscle contraction to flow. Expect clear takeaways you can apply this week: food upgrades, training levers, recovery basics, and lab markers that actually move the needle. Finally, we open the hood on Dave’s AI‑driven supplement schedule—how he used large language models to de‑conflict ~100+ ingredients into practical AM/PM dosing, and why he’s building a personal GPT that ingests labs, wearables, and genetics for personalized protocols. We also level‑set on gene‑therapy hype, “exercise in a pill,” and influencer blueprints versus fundamentals. The mantra we land on is simple: “Comfort is good, capability is better.” Listen in for the frameworks, the mistakes to avoid, and a preview of Part 2, where we’ll walk through Dave’s public playbook so you can build your own. 🎯 Apply for Health Optimization Coaching🔗 https://coaching.knowyourphysio.org/video1729359042808Topics Covered:[00:09:13] Biohacking the human body.[00:13:31] Pace of aging tests.[00:19:14] Marathon training at 50.[00:33:11] AI-driven health optimization.[00:48:30] Fasting and carbohydrate cycling.[00:57:45] Longevity and quality of life.[01:02:14] Supplements and their effectiveness.[01:06:12] Gene therapy and health optimization.[01:12:56] Importance of exercise for health.[01:16:54] Longevity and daily exercise.[01:22:04] Bad science in health products.[01:26:24] Get up and move.[01:30:39] Free resources for healthy living.Resources discussed: TrueDiagnostic’s DunedinPACEDave Pasco Official WebsiteSupport the show
