🎙 What Happens When the Body Lets Go? Werner Klingler on Anesthesia, Altered States & the Physiology of Relaxation What actually happens when the body "lets go" — in anesthesia, trance, or the deep relaxation familiar to hands-on practitioners? Til Luchau talks with Professor Werner Klingler, anesthesiologist, physiologist, and fascia researcher at Ulm University (Germany), whose work bridges clinical anesthesia, neuroscience, and connective-tissue research. Drawing on decades of operating room experience, Dr. Klingler explains how different parts of the brain disconnect and re-synchronize during altered states, why the "freeze reflex" comes first, and how fascia's responsiveness makes it a living sensory organ rather than inert tissue. Fair warning: Werner gets wonderfully detailed about physiology — but stick with it, because he drops some genuine gems about autonomic "push-ups," why tears cleanse neurotransmitters, and what happens when children wake from anesthesia with wide-open pupils. In this episode, they discuss:- The "octopus model" of consciousness — why "altered state" is too simple- The three pillars of anesthesia: unconsciousness, analgesia, and muscle relaxation- How breathing and CO₂ levels influence pH, drug effectiveness, and tissue tone- Why warmth matters: how temperature shifts the load between muscle and connective tissue- What "autonomic push-ups" teach us about resilience and cyclic training- The freeze-then-flight reflex pattern and how it shows up under anesthesia- How emotion and perception shift as anesthesia fades — and why some people wake up sad- Whether sensation is required for bodywork to be effective (spoiler: tissue effects happen either way)- Pre- and post-operative care: what bodyworkers can offer surgery patients- Why fascia is alive — restructuring, remodeling, and central to our sensory and autonomic systems- The FRECLS project: how practitioners can contribute to international fascia research Whether you're curious about the neuroscience of deep relaxation, how anesthesia informs hands-on practice, or what happens when different "arms of the octopus" come back online, this conversation offers a rare clinical perspective on the states we work with every day. ✨ Resources👉 Join the FRECLS project (Fascia Research Consensus and Liaison Statement): https://frecls.org/👉 Fascia Research Society: https://fasciaresearchsociety.org/👉 Video version: https://www.youtube.com/@AdvancedTrainings/podcasts Sponsor Offers:- Books of Discovery – Save 15% with code thinking at https://booksofdiscovery.com/- ABMP – Save $24 on new membership at https://abmp.com/thinking- Advanced-Trainings – Try one month free of the A-T Subscription at https://a-t.tv/subscriptions/ with code thinking- Academy of Clinical Massage – Grab Whitney's free Assessment Cheat Sheet at https://academyofclinicalmassage.com/cheatsheet ✨ Connect with us:Til Luchau – https://advanced-trainings.com | Facebook | InstagramWhitney Lowe – https://academyofclinicalmassage.com | Facebook | Twitter 📧 Email us: info@thethinkingpractitioner.com The Thinking Practitioner Podcast is intended for professional practitioners of manual and movement therapies — bodywork, massage therapy, structural integration, physical therapy, osteopathy, and similar professions.
