Outro

Chronic stress is quietly reshaping how we think, perform, sleep, and recover. In a world optimized for productivity, we rarely prioritize the one variable that determines long term resilience: recovery.

In this episode of Extend, we sit down with Dr. Dave Rabin, neuroscientist, psychiatrist, and co founder of Apollo Neuro, to unpack the science of vagal tone, heart rate variability, and how safety signals in the body drive peak performance and mental health. We break down the difference between eustress and distress, how unresolved trauma suppresses recovery, why HRV may be the most powerful biomarker of resilience, and how tools like breath, environment design, and wearable neurotechnology can retrain the nervous system in real time.

We also explore how psychedelic assisted therapies such as ketamine and MDMA are reshaping psychiatry, why safety is the foundation of trauma healing, and how small daily practices can restore autonomic balance and unlock human potential.

Dr. Dave Rabin, MD, PhD, is Executive Director of The Board of Medicine and a psychiatrist and neuroscientist specializing in chronic stress and treatment resistant illness. He has spent 15 years researching non invasive therapies including MDMA assisted treatment for severe PTSD, and is the author of the upcoming book A Simple Guide to Being Alive, a science backed framework for navigating burnout and reclaiming mental clarity in the modern world.
