Summary
In this episode, we talk to David Herrera to explore why biology, not motivation, determines follow-through, discipline, and health.We dive deep into how light exposure, dopamine, circadian rhythm, cold, and modern environments shape everything from energy levels and sleep to hormones, mood, addiction, and long-term disease risk. From blue light and melatonin to vitamin D myths, sunscreen, seed oils, and why kids spend less time outside than prisoners, this conversation challenges nearly everything we’ve been taught about “health.”This isn’t about hacks.It’s about restoring the inputs humans evolved with.References:https://x.com/DrJackKruse/status/2009355665538720248David's House:https://www.loom.com/share/0d2d864b0c724a6390f1096915a19e21Monitor mentioned:https://spectrumview.com/Special perks for our listeners below!🥩 HIGH QUALITY PROTEIN! 🍖 ➢ https://goodlifeproteins.com/ Code POWER to save 20% off site wide, or code POWERPROJECT to save an additional 5% off your Build a Box Subscription!🩸 Get your BLOODWORK/TRT/PEPTIDES! 🩸 ➢ https://marekhealth.com and use code "POWERPROJECT" for 10% off Self-Service Labs and Guided Optimization®.🧠 Methylene Blue: Better Focus, Sleep and Mood 🧠 Use Code POWER10 for 10% off!➢https://troscriptions.com?utm_source=affiliate&ut-m_medium=podcast&ut-m_campaign=MarkBel-I_podcastBest 5 Finger Barefoot Shoes! 👟 ➢ https://Peluva.com/PowerProject Code POWERPROJECT15 to save 15% off Peluva Shoes!Self Explanatory 🍆 ➢ Enlarging Pumps (This really works): https://bit.ly/powerproject1Pumps explained: https://youtu.be/qPG9JXjlhpM?si=JZN09-FakTjoJuaW🚨 The Best Red Light Therapy Devices and Blue Blocking Glasses On The Market! 😎➢https://emr-tek.com/Use code: POWERPROJECT to save 20% off your order!👟 BEST LOOKING AND FUNCTIONING BAREFOOT SHOES 🦶➢https://vivobarefoot.com/powerproject🥶 The Best Cold Plunge Money Can Buy 🥶 ➢ https://thecoldplunge.com/ Code POWERPROJECT to save $150!!➢ https://withinyoubrand.com/ Code POWERPROJECT to save 15% off supplements!➢ https://markbellslingshot.com/ Code POWERPROJECT to save 15% off all gear and apparel!Follow Mark Bell's Power Project Podcast➢ https://www.PowerProject.live➢ https://lnk.to/PowerProjectPodcast➢ Insta: https://www.instagram.com/markbellspowerproject➢ YouTube: https://www.youtube.com/markbellspowerprojectFOLLOW Mark Bell➢ Instagram: https://www.instagram.com/marksmellybell➢https://www.tiktok.com/@marksmellybell➢ Facebook: https://www.facebook.com/MarkBellSuperTraining➢ Twitter: https://twitter.com/marksmellybellFollow Nsima Inyang➢ Ropes and equipment : https://thestrongerhuman.store➢ Community & Courses: https://www.skool.com/thestrongerhuman➢ YouTube : https://www.youtube.com/c/NsimaInyang➢ Instagram: https://www.instagram.com/nsimainyang/?hl=e#PowerProject #Podcast #MarkBell #FitnessPodcast #markbellspowerproject
