EPISODE 146: HOW CHRONIC STRESS REWIRES THE BRAIN (AND HOW TO REVERSE IT) with Dr. Dave Rabin

STUCK IN FIGHT OR FLIGHT? HERE’S HOW TO RETRAIN YOUR NERVOUS SYSTEM

WHY TRAUMA KEEPS YOUR BODY STUCK IN SURVIVAL MODE

HOW TO REWIRE FEAR RESPONSES AND FEEL SAFE AGAIN

Kristin sits down with Apollo Neuro co-founder, Dr. David Rabin, as they dive deep into the science of safety, nervous system regulation, and the future of trauma healing. From PTSD and fear learning to wearable technology that helps the body shift out of fight-or-flight in real time, this conversation explores how stress reshapes the brain—and how we can retrain the nervous system toward resilience. Dr. Rabin breaks down the connection between vagus nerve activity, heart rate variability, sleep, emotional regulation, and psychedelic-assisted therapy in a way that feels practical, grounded, and deeply human. The discussion also touches on elite athletic performance, trauma integration, meditation, ketamine and MDMA-assisted therapy, and why true healing starts with restoring a sense of safety in the body. Through powerful personal stories, cutting-edge neuroscience, and actionable tools, this episode reveals how technology, breath, and awareness can work together to help us feel calm, present, connected, and fully alive again.
