About this episode
Dave Asprey discusses a 9,000-year-old ritual involving heat and cold to alleviate brain fog and improve mental clarity.
I spent fifteen years living with brain fog until I realized the problem wasn’t in my brain, but in a nervous system stuck in a survival mode that pulls energy away from focus and memory. In this video, I explain why "trying harder" or popping supplements rarely works, and instead, I show you the 9,000-year-old ritual of heat and cold that pulls your body out of stress mode so clarity can actually return. I break down the specific science of how I use infrared wavelengths and contrast therapy to retrain the brain to stay calm under pressure, moving beyond temporary fixes to target the root cause of mental fatigue. Follow this protocol to finally complete your body's stress cycles, reset your biological default settings, and reclaim the lasting mental performance you’ve been missing. 00:00 – Introduction 01:02 – What Brain Fog Really Is 03:00 – Why Trying Harder Doesn't Work 04:51 – Supplements: Useful But Not Enough 06:14 – Why Sauna Works 07:32 – Infrared vs Traditional Sauna 08:02 – Sunlighten Sauna Overview 09:28 – Sauna Routine & Protocol 10:34 – Why Home Access Matters 11:41 – Post-Session Recovery 12:11 – Contrast Therapy 13:11 – How to Do Contrast Therapy 13:54 –…
