It is the question people ask me last.
Not first — last, usually at the end of a call, in a slightly different voice, after we have covered scheduling and cost and whether Tuesdays work.
Do I have to go back through it?
I understand why it arrives late. Asking it out loud means admitting you are afraid of the thing that is supposed to help you, and most people would rather not say that to a stranger they are considering hiring.
So let me answer it properly: with the mechanism, and with what the research actually supports, including the parts my field is less keen to discuss.
The short answer, and then the honest one
No. Going back through the event in detail is not the mechanism.
I want to be careful here, because “no” is precisely what you want to hear, and I am not interested in being the practitioner who tells people what they want to hear. I have written before about how to judge a method that is being sold to you, and I would rather be held to that standard than exempt from it.
So the more accurate version is this: what makes this work effective is not how much of the material you re-enter, but how little. That is not reassurance. It is a design principle, and it has a name.
Titration
In somatic work, titration means approaching activation in the smallest useful amount — not the largest amount you can survive.
Not the memory in sequence, not the narrative, and not the worst ten minutes of your life recounted in order. A sensation, briefly, with somebody tracking what happens in your body while you are near it. Then away from it again.
The term is borrowed from chemistry, which is part of why I trust it. You add the reagent one drop at a time because the goal is to reach the point of change, slowly, slowly. Adding it all at once doesn’t speed up the reaction. It produces a mess, and you begin again tomorrow.
Nervous systems behave similarly. Overwhelm is not an accelerated form of processing — it is the absence of processing, which is a distinction worth holding onto.
Pendulation, which is the part rarely explained
If titration is the dose, pendulation is the rhythm.
You move toward the activation a little, then deliberately back toward something that is genuinely unremarkable: the weight of the chair, the temperature of the room, the fact that nothing in it is currently a threat. Then toward it again, and away again, several times.
This is not avoidance wearing a technical name. It is the full mechanism itself. Each pass teaches the nervous system something it has not yet learned — that it can approach this and return. That proximity is survivable, that the door opens from the inside.
You are not building tolerance for the memory. You are building tolerance for your own arousal, which is a different and considerably more useful thing. The zone in which that becomes possible is what clinicians call the window of tolerance, and I have written about why your emotional range is not a character flaw if you want the fuller version.
Why talking about it harder does not resolve it
This is the part that explains a great deal of disappointing therapy.
Traumatic material is not held primarily as narrative. It is encoded subcortically — amygdala, brainstem, body — in systems that were operating long before language arrived, and that are triggered by sensory cues rather than by sentences.
During high activation, the prefrontal cortex reduces its involvement. A systematic review of the PTSD neuroimaging literature lists decreased activity in Broca’s area during symptom provocation among its replicated findings, alongside increased amygdala activation, and suggests this may explain the difficulty people have in putting the experience into words.[1] May explain — the review is careful, and so am I.
The consequence is practical. Asking someone to produce a calm, coherent, detailed verbal account while they are activated asks the part of the brain that has gone quiet to do the work. That is not a motivation problem or a resistance problem. It is an availability problem.
Which is why somatic approaches work from the bottom up: regulate the state first, and allow meaning to follow. I have written separately about why insight alone does not change the pattern, including the measured size of insight’s contribution, which is smaller than most people assume.
The distinction that actually answers the question
Here is the one I most want you to leave with, because it is rarely stated plainly and it is the whole answer.
Discharge is not catharsis.
Catharsis is the visible release: the sobbing, the shouting, the scene. It photographs well, and a certain kind of workshop sells it energetically.
Discharge is something else entirely. It is subtle and involuntary — a tremor through the legs, a change in breathing, a shift in temperature, a yawn arriving from nowhere, a small movement the body makes without consulting you first. It is not a performance of feeling. It is a physiological event, and it does not require forceful emotional expression to occur.
You do not have to work yourself up to it. Mostly, you have to stop interrupting it.
So when you ask whether you will have to relive it, what you are picturing is catharsis. And catharsis is neither the target nor a reliable indication that anything useful has happened.
What the evidence supports, stated accurately
I am not going to tell you this is settled science, because it is not, and you can check.
Somatic Experiencing has one randomised controlled trial in PTSD: 63 participants, waitlist-controlled, with large effect sizes on symptom severity.[2] That is a real finding, and it is also a single study against a waiting list, which is the weakest available comparator.
A 2021 scoping review of the wider literature found the results promising while stating that overall study quality is mixed and that the field requires unbiased randomised trials it does not yet have.[3]
The strongest evidence in body-based work is in yoga. Sixty-four women with chronic, treatment-resistant PTSD were randomised to trauma-informed yoga or a supportive women’s health education control. By the end, 52% of the yoga group no longer met criteria for PTSD, against 21% of controls.[4]
One correction while I am here, because I have contributed to the error myself. You may have encountered the claim that this study showed yoga outperforming medication. It did not. There was no medication arm. The authors wrote that the effect sizes were comparable to well-researched psychotherapeutic and psychopharmacological approaches — comparable to, not better than. I have repeated the stronger version in the past, and I am correcting it here.
So: promising, not proven. Trauma-focused talking therapies retain the larger evidence base. Anyone presenting somatic work as settled science is selling something, and anyone dismissing it entirely has not read the trials either.
What the room actually looks like
If you do sit down with me, this is the shape of it.
You will not be asked to tell the story in order. You will not be asked to go to the worst part to demonstrate commitment. You will be asked what you notice, now, in a fairly ordinary way, and we will proceed in increments that you set.
If it becomes too much, we stop and return to something steadier; you are the one in charge, always. That is not the session failing — stopping is part of the method, and knowing when to is most of the skill. If you want a fuller picture of the practical side, I have written about what to expect in a first session with a somatic practitioner.
And if something does arrive — a tremor, a wave of heat, tears with no story attached — that is discharge rather than collapse, and it usually passes more quickly than people expect.
I hold a doctorate in medicinal chemistry, not in medicine. I am not a physician. I do not diagnose, and I do not treat. Only a clinician can tell you what you have. What I work with is what living inside it has done to you.
If you are currently in acute crisis, this is not the right work for this week. Stabilisation comes first, with someone qualified to provide it. That is not a deflection; it is the clinical order of operations, and any practitioner who skips it is doing you harm.
The question underneath the question
I suspect that when people ask whether they will have to relive it, they are often asking something adjacent.
They are asking whether this is going to cost more than they currently have.
Which is an entirely reasonable thing to establish before handing yourself to someone.
So, as directly as I can put it: this work is not designed around endurance. It is designed around dose. Done well, you should leave most sessions feeling that rather less happened than you had braced for.
That is not the session underdelivering. That is what precision looks like from the inside.
What might you do differently this year, if you knew it would not require going back through the worst of it?
Frequently asked questions
Do I have to talk about my trauma in detail to heal from it?
No. Detailed narrative retelling is not the mechanism in somatic approaches. They work through titration — approaching activation in very small increments — and pendulation, the deliberate oscillation between activation and a settled state, which builds the nervous system’s capacity to approach and recover rather than requiring full re-entry into the memory.
Will somatic therapy retraumatise me?
Titration exists specifically to prevent that. The practitioner tracks somatic cues — breathing, muscle tone, skin colour, posture — to keep the work inside the window of tolerance, because processing does not occur outside it. Overwhelm is not faster processing; it is the absence of processing.
Is somatic therapy evidence-based?
Partly, and honestly: promising rather than proven. Somatic Experiencing has one randomised controlled trial in PTSD with large effect sizes, and a 2021 scoping review found overall study quality mixed and called for unbiased randomised trials. Trauma-informed yoga has stronger support, including a trial in which 52% of participants no longer met PTSD criteria versus 21% of controls.
What is the difference between discharge and catharsis?
Catharsis is forceful emotional expression — crying, shouting, visible release. Discharge is subtle and involuntary: trembling, changes in breathing, shifts in temperature, small spontaneous movements. Discharge is the physiological completion of an interrupted survival response and does not require emotional catharsis to occur.
