Why Do I Self Harm? A Somatic Look at Where It Starts
A note before you read. This is an article about where an urge may come from, not about what to do in a crisis. If you are in danger right now, or you are not sure whether you are, that is a different conversation and it needs a person, not a blog post. Resources are at the bottom of this page. Introduction If you have ever typed why do I self harm into a search bar and closed the tab because none of it fit, you are in reasonable company. Most of the available explanations describe what self harm does. It regulates. It makes something internal into something external and legible. It produces a feeling when there has not been one in a while. Some of the explanations are worse than incomplete, and the one about attention is often the worst of them, because it is wrong and because it gets used to dismiss people. What almost nobody offers is a physiological account of where the impulse originates. I am a Somatic Experiencing Practitioner, Somatic Educator and Bodyworker, and I work with the physiological symptoms of stress. I am trauma-trained, which is not the same thing as trauma-informed. This article contains one possible origin. It is not the only one, it will not fit everyone reading this, and it is offered as something to hold up against your own experience rather than something to accept. Start with what your body did when it was in danger When a mammal is threatened, it mobilizes. That mobilization is a real and measurable amount of neurochemistry and muscular preparation, organized very precisely toward a target. Your jaw sets, your forearms and shoulders load, your legs prepare, and a large amount of  survival energy comes online. That system works beautifully when there is somewhere for the energy to go. You fight, or you run, the threat resolves, the stress hormone ones get metabolized, and your physiology comes back down to baseline or something close to it. Now change one variable. Make the threat inescapable. Not inconvenient, not difficult. Inescapable, in the way it is inescapable when you are small and the danger is the person who feeds you, or when leaving is not survivable, or when fighting back has already been tried and the result was worse. In those conditions your body still produces the mobilization, because that part is automatic and not under your control, it is biology. It also has to suppress every outward expression of it, because expressing it would get you hurt. So you end up with a system doing two enormous jobs at once. Producing an aggressive, targeted, fully organized response, and simultaneously holding all of it down, in, and all while often trying to maintain normalcy. The energy does not evaporate Survival energy is big, and it does not simply dissipate when it goes unused. It creates back pressure in the body, and it stays organized around the percieved target, because that is how our nervous systems evolved. When the actual threat target is unavailable, either because they are gone, they are still in your life, or because directing anything at them was never survivable in the first place, that pressure in your nervous system does not stop looking for a place to land. There is exactly one body in the room that can receive it without anyone getting killed. That is one possible origin of self harm. Not a character defect, bad habit, or manipulation. It is an accurate defensive response, correctly produced in response to real danger, that was given one available route and took it. Self harm has more than one origin. For some people it is primarily about regulation when everything is either too much or completely flat. For some people it is tangled up with shame in a way that is more about punishment than about aggression looking for an exit. For some people it has nothing to do with any of this. I am describing a mechanism I see often in people with long histories of inescapable danger, and I am describing it because when it is the right explanation, it changes what helps shift the pattern. Four things this explains that “coping mechanism” does not Why willpower makes it worse. If you try to white-knuckle it, you are adding suppression on top of a mobilization that is already suppressed. The pressure has not gone anywhere, and now it has less room…and more pressure. People commonly experience this as a period of doing well followed by a sharp return, and then conclude the problem is that they are weak. The problem is that the energy wasn’t given any other pathway to go. Why the urge spikes right after a good stretch. This one confuses people. You have a strong session, or a good few weeks, or something in your life improves, and the urge comes back harder than it has in months. That is not backsliding. As capacity comes up, more of what was being held down becomes available, and the old neuropathway is the fastest exit your physiology knows. Why substitution advice mostly fails. Ice cubes, elastic bands, cold water. All of these are still pain used as a regulator. It is the same neuropathway at a lower dose, which is why it either does nothing or works for about a week. That advice gets handed out constantly by well-meaning people missing important pieces to the puzzel. Why the thing that reduces it never targets it directly. In practice, what tends to bring this pattern down is work on capacity and work on healthy aggression having a legitimate neuropathway to express and metabolize. Boundary work. The physical expression of pushing something away. The word no, said out loud, in a body that is allowed to mean it. None of that is aimed at the self harm pattern; the self harm often quiets, because you are dealing with reducing the pressure rather than the exit. The shame afterward is part of
