The Science of Tension Release
A 2-Hour Continuing Education Workshop for TYC Teachers
2026 Teacher Preparation • Trauma-Informed • Evidence-Aware • Practical
Why this update matters As in any profession, continuing education provides opportunity to apply evidence-based learning alongside traditional and experiential practices, for creating best practices unique to the populations we serve. The original 2023 evidence-based Life Fit Inc Trauma-Informed Training was created for teachers of The Yoga Connection 501c3, to prepare for a data collecting semester supporting a research project assessing the effectiveness of the program. TYC is dedicated to serving its missions with careful and creative blending of science with tradition in offering yoga therapy to new arrival immigrant and refugee women. There are many facets of this 2 CEC course that are relevant to mind-body professionals, especially the February 2026 literature centered on the emerging scientific controversy surrounding Polyvagal Theory, PT. The new perspective in continuing to use PT in yoga, and in particular at TYC, emphasizes that practitioners can continue to value practices such as mindful movement, breathing, grounding, vocalization, and relational safety without presenting Polyvagal Theory as settled neuroscience. This revised teacher continuing education keeps that central message and translates it into concrete teaching decisions, relevant to all trauma-informed mind-body practitioners looking to incorporate evidence-based theoretical models with traditional models of their profession.
Thank you for your decision to take this training! Your presence will help to shape future growth in how we can serve and empower the people who entrust our help with their wellness journeys.

The Science of Tension Release
-
Learning Objectives + Agenda
By the end of this 2-hour workshop, TYC teachers will be able to:
Describe, in accessible language, the difference between stress, tension, autonomic regulation, and the experience of feeling safe or settled.
Summarize why Polyvagal Theory is under significant scientific scrutiny in 2026 and distinguish a scientific model from established fact…
-
Part I — Understanding Tension Release
“Tension release” is useful teacher language when it describes a student's lived experience rather than a promised physiological event. Muscular effort, protective bracing, attention, breathing patterns, emotion, pain, fatigue, environmental stress, and interpersonal context can all influence how a person experiences tension. A yoga teacher does not need to determine the hidden cause in order to offer a skillful practice.

Part II — 2026 Science Update: Polyvagal Theory
A published article in Clinical Neuropsychiatry, February 2026, by Paul Grossman and 38 other researchers challenges several core neurophysiological and evolutionary claims of Polyvagal Theory, including assumptions about respiratory sinus arrhythmia, vagal anatomy and function, and the evolutionary organization of social behavior. The authors conclude that major tenets of the theory are not supported by current evidence.
-
Part III — Practice Lab: Regulation Without Overclaiming
Explore each category as a teacher and as a participant. Ask: What can I reasonably observe? What choices can I offer?
-
Part IV — Trauma-Informed Teaching Refresh
Trauma-informed teaching does not require a teacher to know a participant's trauma history. It asks us to consider how choice, predictability, power, language, sensory input, physical proximity, and pace may affect participation.

Selected References & Current Reading
Facilitator note: This handout is educational and intended for TYC yoga teachers. It does not provide medical or mental-health treatment guidance. The 2026 Polyvagal Theory discussion is presented as an active scientific debate; teachers should avoid overstating either the critique or the theory's claims.
