Fight, Flight, Freeze — Understanding Your Stress Response and How Hypnotherapy Can Help
Have you ever snapped at someone and immediately wondered where that came from? Or found yourself completely frozen — mind blank, unable to speak — when you needed to hold your ground? Or felt your heart hammering before a conversation you'd been dreading for days?
These aren't personality flaws or signs that something is wrong with you. They're your nervous system doing exactly what it was designed to do. Understanding that can be genuinely liberating — and it's often where we start in our work together.
Your Brain's Alarm System
Your body naturally activates the fight-flight-freeze response as a survival mechanism. When your brain perceives a threat — real or imagined — your amygdala fires before your conscious mind has even caught up. Stress hormones flood your system. Your heart rate rises, your muscles prepare for action, and your digestion slows. All of this happens in milliseconds, and none of it requires your input.
Walter Cannon first described the fight-or-flight response in the 1920s (Cannon, 1929). We now understand it also includes freeze — that deer-in-headlights sensation of being stuck or shutting down (Schmidt et al., 2008) — and what trauma researcher Pete Walker calls the fawn response: appeasing, people-pleasing, making yourself small in order to feel safe (Walker, 2013).
Each of these is a legitimate survival strategy. The problem is that our nervous systems haven't quite caught up with modern life. The same cascade that would have helped an ancestor escape a predator gets triggered by a difficult email, a tense meeting, or a conversation we've been putting off. And unlike a predator encounter — which ends — modern stressors can grind on for months.
What Each Response Actually Feels Like
Fight might look like irritability, defensiveness, or anger that feels out of proportion. It can also be subtler — a tightening in the chest, clenched jaw, a sharpness in your tone that surprises even you.
Flight might be the urge to leave the room, avoid the situation entirely, or keep yourself constantly busy so you never have to sit with what's bothering you. Anxiety and panic attacks often have a strong flight flavour.
Freeze can feel like going blank mid-conversation, dissociating, struggling to make decisions, or that heavy, stuck quality where even getting off the sofa feels impossible.
Fawn — perhaps the least talked about — involves becoming agreeable, helpful, self-effacing in the face of perceived threat. If you find it difficult to say no, struggle to identify what you actually want, or find yourself managing other people's emotions at the expense of your own, this might resonate.
When the System Gets Stuck
For most people, the stress response activates and then settles — the threat passes, the nervous system returns to baseline. But sometimes that settling doesn't happen, and the system gets stuck in a state of chronic low-level activation.
You might recognise this as persistent anxiety, difficulty sleeping, a short fuse, physical tension that never quite goes away, or a sense of just waiting for the next thing to go wrong. Van der Kolk's work describes how unresolved stress and trauma becomes held in the body, shaping automatic responses long after the original experience has passed (van der Kolk, 2014).
This is where hypnotherapy becomes particularly relevant.
Why Hypnotherapy Works for This
The fight-flight-freeze response lives below the level of conscious thought — which is partly why simply knowing about it doesn't always help. You can understand exactly what's happening neurologically and still find yourself freezing, snapping, or spiralling. Insight is useful, but it doesn't automatically change the pattern.
Hypnotherapy works at the level where these patterns actually operate. In a state of relaxed, focused attention, the subconscious becomes more accessible — and more open to change. We can gently approach the material that keeps the nervous system on high alert, process it at a pace that feels safe, and begin to build new, calmer response patterns in its place.
Research supports hypnotherapy's effectiveness for anxiety and trauma-related presentations. A meta-analysis by Valentine et al. (2019) found significant reductions in anxiety symptoms compared to control conditions. A systematic review by Rotaru and Rusu (2016) found hypnotherapy effective in reducing PTSD symptoms, particularly intrusion and avoidance.
In practice, the work might include:
Building a felt sense of safety — many clients with an overactive stress response have never really experienced what it feels like to be in their body without bracing. Hypnotherapy can create that experience, often for the first time in years.
Rewind and reframe work — where the stress response is linked to specific experiences or memories, these techniques can neutralise the emotional charge and create a new, calmer template. I've written more about this in my post on reframing in hypnotherapy.
Future templates — rehearsing, in hypnosis, a calmer version of situations that currently trigger a strong response. The brain doesn't always distinguish well between vividly imagined and real experience, which is what makes this so powerful.
Self-hypnosis — something I teach all my clients, so the work continues between sessions and you build genuine capacity to regulate your own nervous system over time.
What You Can Do Right Now
If your stress response feels overactive, a few things can help in the short term.
Slow your breathing down — particularly the out-breath. Extended exhalation activates the parasympathetic nervous system and genuinely shifts your physiological state. You don't need a specific ratio, just breathe out for longer than you breathe in.
If anxiety is rising, try the 5-4-3-2-1 grounding technique — noticing five things you can see, four you can touch, three you can hear, two you can smell, one you can taste. It works by redirecting attention to the present moment and interrupting the stress spiral.
And if you recognise yourself in the freeze or fawn descriptions particularly — if the pattern feels deep or long-standing — it's worth knowing that this kind of work takes time and the right pace. I work in a trauma-informed way and always follow your nervous system's lead.
A Word on Trauma
If you suspect your stress response has been shaped by earlier difficult experiences, you're not alone — and you're not stuck with it. Neuroplasticity means the brain retains the capacity to form new patterns throughout life. But this work benefits from proper support, not just willpower or self-help.
If you'd like to explore whether hypnotherapy might help, a free consultation call is a good place to start. No pressure — just a conversation.
