In this episode, we explore how trauma memories can be stored as sensory fragments and threat predictions, why triggers can feel like the event is happening again, and how avoidance develops as a protective strategy that can shrink life over time. Using simple polyvagal-informed language, we look at mobilised protection (fight/flight) and shutdown, and offer practical first steps for helping the nervous system update from “then” to “now.” We close with a grounding practice that uses the senses plus a temperature cue to anchor the present moment.In this episode, you’ll learnA clear definition of single-incident trauma (overwhelm + stuck protection afterwards)Why the brain prioritises survival over storytelling during overwhelmThe difference between reminders and triggersPolyvagal-informed patterns: hypervigilance vs shutdown, and cycling between themCommon post-incident signs (non-diagnostic): intrusive replay, startle, avoidance, checking, sleep disruptionWhat helps: normalisation, gentle exposure, completing the stress cycle, trauma-informed supportA short grounding practice to signal “this is now”Grounding practice (2–3 minutes): “5–4–3–2–1 + Temperature”5 things you see4 things you feel3 things you hear2 things you smell (or imagine)1 thing you tasteNotice one temperature cuePhrase: “This is now.
