4 Things Killing Your Cells (And 5 Levers That Reverse It)

Are you eating well, moving your body, and trying to sleep better — but still feeling older than you should? Stiffer joints, lower energy, and a sense that the last few years have aged you faster than the years before? That feeling has a cause, and it is not laziness or bad genetics. In this episode, we dive into why aging happens inside your cells first, and how your body catches up later. I walk through the 4 specific drivers that accelerate cellular aging and the 5 evidence-backed levers you can use to slow — and in some cases reverse — that process. Stay until the end for the clinical trial where participants did not just slow cellular aging… but after five years, they measurably turned it backward. In this episode, you'll learn: • Why your biological age — not the number on your driver's license — determines how you feel, think, and move • The 4 key mechanisms breaking down your cells right now, including telomere shortening, mitochondrial decline, slowed autophagy, and senescent cell buildup • How telomeres work like the plastic tips on a shoelace, and why emotional stress wears them down faster than almost anything else • What autophagy is, why your cellular cleanup crew slows with age, and how to switch it back on • Why resistance training is the single most powerful tool for building new mitochondria and slowing cellular aging • The specific fats that keep your cell membranes flexible and springy — and the ones that make them brittle • How deep sleep triggers growth hormone release, clears damaged proteins, and runs the brain's overnight repair cycle • The 9 blood biomarkers from a 2018 study in the journal Aging that predict longevity better than chronological age • The five-year lifestyle trial where one group lengthened their telomeres by 10% while the control group's shortened by 3% Download the FREE Cellular Repair Guide here: https://bit.ly/draxecellrepair Find out what's really happening inside your body with advanced at-home biomarker testing — which includes a 60 minute consultation to review your results and learn about our cellular healing protocols at The Health Institute → http://mybloodwork.com Thank you to our sponsors!
