Brain Fog Starts in Your Feet (Scientifically Proven) : 1476

Episode Description from the Publisher

I lived with severe brain fog for 15 years. I couldn't focus, my words didn't come easily, and I spent a fortune trying to fix it from the top down...little worked until I realized the problem wasn't in my head—it was in my feet.In this video, I break down the scientifically proven connection between your feet, your circulation, and your cognitive decline. We cover how your brain requires a massive 20% of your body's oxygen to function, and why sitting at a desk all day weakens the calf muscles that act as a "second heart" to pump that oxygenated blood back up to your skull. I also explain how modern cushioned shoes act as sensory deprivation chambers, muffling the critical signals your feet send to your brain. This sensory lack forces your nervous system into a constant, low-level survival state that completely kills your executive function. You don't need another brain supplement to get your mental edge back. You need to fix your foundation. I share the exact barefoot walking and foot-strengthening protocols I used to lift the fog and restore my cognitive sharpness.Thank you to our sponsors!Suppgrade Labs | Grab your DAKE and Minerals 101 duo at shopsuppgradelabs.com and use code DAVEPOD for 15% off todayEssentia | Go to https://myessentia.com/daveand use code DAVE for $100 off The Dave Asprey Upgrade.iRestore | Reverse hair loss at www.irestore.com/DAVE and get exclusive savings on the iRestore Elite, use code DAVETimestamps:00:00 – Personal Experience00:47 – Root Cause: Not in Your Head01:05 – Blood Flow and Brain Function02:10 – The Calf Pump03:52 – Foot Sensory Signals04:26 – Nervous System Impact06:22 – How to Fix It07:51 – Personal ResultsConnect with Dave Asprey!Website: https://daveasprey.comTikTok: https://www.tiktok.com/@daveaspreyofficialInstagram: https://www.instagram.com/dave.asprey/Facebook: https://www.facebook.com/Daveaspreyofficial/X: https://x.com/daveaspreyYouTube: https://www.youtube.com/c/daveaspreybprThe Human Upgrade Podcast: https://www.instagram.com/TheHumanUpgradePodcast/ https://m.facebook.com/Thehumanupgrade/Danger Coffee: https://dangercoffee.com/DAVE15Dave Asprey’s BEYOND Conference: https://beyondconference.com/Dave Asprey’s New Book - Heavily Meditated: https://daveasprey.com/heavily-meditated/Dave's favorite supplements: https://www.shopsuppgradelabs.com/discount/DAVE15Upgrade Labs: https://upgradelabs.com40 Years of Zen: https://40yearsofzen.comSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
