It can be, with the right practitioner and careful assessment. For single-incident trauma where the nervous system is stuck in a loop around a specific event, hypnotherapy is well-suited. The freeze response, which is the foundation of my Freeze to Forward method, is prominent in many trauma presentations and responds well to a polyvagal-informed approach. When someone has experienced something that their nervous system could not fully process at the time, it often stores that experience as an unresolved threat. The body stays in a state of readiness that was appropriate then and is exhausting now.
What hypnotherapy is not appropriate for is complex or developmental trauma without clinical oversight. I do not use techniques that involve revisiting or reliving traumatic material, because that approach can be retraumatising without proper clinical training. If someone presents with a severe or unprocessed trauma history, I assess carefully and work alongside a trauma-specialist psychologist where needed.
As one of the few hypnotherapists in Edinburgh with a neuropsychology background from the University of Edinburgh, I can make those clinical distinctions in a way that generalist practitioners often cannot. Trauma work requires knowing exactly where your competence boundaries lie. That is not a limitation I apologise for. It is part of what makes the work safe.
