Understanding Self-Harm: Compassionate Information and Support

Self-harm is one of the most misunderstood behaviours in mental health, surrounded by myths, judgement, and a great deal of fear, both in those who self-harm and in the people who love them. This article is written for people who self-harm, for those supporting someone who does, and for clinicians who want to ensure their language and practice reflect current understanding rather than outdated assumptions. The aim is to provide a compassionate, evidence-informed account of what self-harm is, why it happens, and how recovery genuinely works, without describing methods or in any way normalising or glamorising the behaviour.

If you are reading this and you are currently in crisis, please reach out to someone who can help. The Samaritans can be reached on 116 123 at any time, day or night, free from any phone in the United Kingdom, with calls not appearing on phone bills. Shout, a confidential text service, can be reached by texting SHOUT to 85258. If you have already harmed yourself in a way that requires medical attention, or if you feel unable to keep yourself safe, please go to your nearest accident and emergency department or call 999. Reaching out is an act of self-respect, not a failure or a weakness.

What Self-Harm Is, and Is Not

Self-harm refers to any act in which a person deliberately causes harm to their own body, typically without an intent to end their life. The behaviour can take many forms, but the focus of psychoeducation should always be on the underlying experience rather than on the specific method, which is why methods are not described in this article. What unites the different forms of self-harm is the function they serve: they are almost always attempts to manage emotional pain that has become unbearable, to feel something when overwhelmed by numbness, to express what cannot be put into words, or to regain a sense of control when other forms of agency feel out of reach.

The clinical literature distinguishes self-harm from suicide attempts, although the two can sometimes overlap and one can sometimes lead to the other. The intent behind most self-harm is to survive an unbearable moment, not to end life. Many people who self-harm are explicit that the behaviour is in fact what keeps them alive, by providing a release valve for emotional pressure that might otherwise become genuinely suicidal. Recognising this distinction matters, because it prevents the panic-driven responses that have historically driven self-harm underground and out of conversation, and because it honours the person's own account of what they are doing. At the same time, self-harm is associated with increased risk of suicide over the longer term, and any episode warrants compassionate attention rather than dismissal.

Self-harm is not, despite the persistence of the myth, attention-seeking. The vast majority of people who self-harm do so privately, often hide it carefully for years, and feel deep shame about it. Where self-harm is visible to others, the visibility is more often accidental than deliberate, and the meaning behind it is more likely to be a quiet plea for understanding than a manipulative gesture. Treating self-harm as attention-seeking is one of the most damaging responses possible, because it adds shame to suffering and pushes the person further from the help they need. The more accurate framing, when attention does seem to be involved, is that the person is experiencing distress that they have no other way of communicating, and that the visibility of the harm is itself a form of communication that should be received with compassion rather than dismissal.

Self-harm is also not the same as a phase that young people grow out of. While adolescence is the most common period of onset, with prevalence highest in the late teens, self-harm continues into adulthood for a substantial proportion of those who develop it, and it can also begin in adulthood, particularly in response to traumatic events or significant losses. Treating self-harm as a passing phase risks missing the opportunity to provide effective intervention during the critical window when patterns are still consolidating.

Prevalence in the United Kingdom

Self-harm is more common than is often realised. The Adult Psychiatric Morbidity Survey, conducted in England every seven years, has tracked self-reported self-harm across the population. The 2014 survey found that approximately 6.4 per cent of adults aged 16 and over had self-harmed at some point in their lifetime, with the highest rates in young women aged 16 to 24, where lifetime prevalence approached 26 per cent. The 2007 survey, by comparison, had found a lifetime prevalence of approximately 4.9 per cent, indicating a significant rise across that period, particularly in young women.

Among adolescents specifically, longitudinal cohort studies have found that approximately 10 to 20 per cent of young people will have self-harmed by the age of 18, with rates particularly high among those who identify as LGBTQ+, those with experience of bullying, and those exposed to early adversity. Hospital presentations for self-harm in the United Kingdom number around 200,000 per year, a substantial underestimate of the true prevalence given that most self-harm does not result in medical attendance.

These figures matter not as abstract statistics but as a reminder that self-harm is something experienced by a great many people, and that anyone who self-harms is part of a much larger group whose experiences have been studied, written about, and increasingly understood by clinicians and researchers. The shame that often surrounds self-harm tends to make people feel uniquely broken; the prevalence data make clear that they are not alone.

Why People Self-Harm

The functions of self-harm vary between individuals and often vary within the same individual at different times. Research consistently identifies several common functions, and understanding which function or combination of functions is operating for a given person is the foundation of any meaningful intervention.

The most frequently reported function is emotional regulation, where the act of self-harm produces a sudden release of tension, a redirection of overwhelming emotional pain into a more containable physical pain, or a calming effect on a nervous system that has become hyperaroused. The biology behind this involves the release of endogenous opioids and other neurochemicals in response to physical injury, which can produce a brief but powerful sense of relief. For many people, this calming effect is the most addictive feature of the behaviour, because it works reliably when other coping strategies have failed.

A second function is the opposite, where the person self-harms to feel something when they have become emotionally numb, dissociated, or detached from their own body. For survivors of trauma in particular, the experience of dissociation can be deeply distressing in its own right, with a sense of not being real, of watching oneself from outside, or of being trapped behind glass. The sharp sensation of self-harm temporarily restores a sense of being present and alive, and for some people the dissociation is itself the trigger for the self-harm rather than the other way around.

A third function is communication, where self-harm expresses what the person cannot put into words. This may be pain that has not been recognised by others, anger that the person feels they cannot voice, distress about something they cannot articulate, or simply the wish to be seen as someone who is genuinely struggling rather than someone who is coping when they are not. The communicative function is most often unconscious; the person is not deliberately sending a message, but the act nonetheless communicates something that has no other channel.

A fourth function is self-punishment, where the person believes they deserve to be hurt because of who they are, what they have done, or what they have failed to do. This function is common in those whose early environment was punitive or who have absorbed deep shame about themselves. The self-harm enacts the punishment that the person feels is owed, often providing a sense of relief precisely because the internal accusation has been answered. This function is particularly common in those with complex trauma histories.

A fifth function is the establishment of control. For people who have experienced situations in which they had no agency, particularly in childhood, the body can become the one domain over which they have control, and self-harm can be a way of enacting that control. This function tends to overlap with eating difficulties, where similar dynamics can be present.

These functions are not mutually exclusive, and most people who self-harm experience multiple functions at different times or even in the same episode. The clinical task is to understand which functions are most active for the individual, because effective intervention needs to address the actual function, not the surface behaviour.

The Cycle of Self-Harm

For many people, self-harm follows a recognisable cycle that, once understood, can be intervened upon at multiple points.

The cycle typically begins with a build-up of emotional pressure. This may be triggered by interpersonal stress (an argument, a perceived rejection, a difficult interaction at work), by intrusive memories or flashbacks, by the activation of long-standing shame or self-loathing, by the accumulation of smaller daily stressors, or by physiological factors including poor sleep, hunger, or premenstrual hormonal shifts. The pressure builds gradually, often over hours or days, and during this build-up phase the person may experience increasing tension, racing thoughts, irritability, and a sense of mounting urgency.

At some point the pressure crosses a threshold beyond which the person can no longer tolerate it. This threshold varies between individuals and within individuals at different times. Once crossed, the urge to self-harm becomes very strong, and the person may experience a narrowed focus on the act, a sense that nothing else will work, and a kind of dissociative detachment from the consequences. The actual act of self-harm typically follows, although there is often a window of seconds or minutes during which the person could still pull back.

Self-harm produces a sudden release. The emotional pressure drops, the tension eases, and the person often experiences a period of relative calm or emotional numbness lasting from minutes to hours. Some people describe this as the only peace they get, which is part of why the behaviour is so reinforcing.

After the calm, the post-self-harm phase begins. Shame, regret, and self-criticism typically return, often more intensely than before, particularly if the person had to hide the harm or if they have to manage the practical consequences (wound care, hiding from others, deciding whether to seek medical attention). The shame and self-criticism add to the underlying emotional load and contribute to the pressure that leads to the next episode, completing the cycle.

Recognising the cycle, and particularly the points at which intervention is possible, is one of the central tasks of recovery. The most amenable point is usually the early stages of pressure build-up, when distraction, grounding, distress tolerance skills, or reaching out to a trusted person can reduce the pressure before it crosses the threshold. The threshold itself is harder to intervene on, but even there, techniques such as cold water on the face, sustained intense exercise, or temporary delay (the "fifteen minute rule" of waiting fifteen minutes before acting on the urge) can sometimes break the chain. The post-self-harm period is also a critical intervention point, because compassionate self-talk, careful wound care, and reaching out to someone trustworthy are all protective against the shame spiral that drives the next episode.

Self-Harm and Suicidal Intent: The Important Distinction

The relationship between self-harm and suicide is complex and often misunderstood. Most self-harm is not a suicide attempt. The intent is to manage unbearable internal experience, not to die. Many people who self-harm are clear that the behaviour is in fact what keeps them alive, providing a way to discharge emotional pressure that might otherwise become genuinely life-threatening.

At the same time, self-harm is associated with increased risk of suicide over the longer term, particularly in those with repeated episodes, those who use methods of higher lethality, those with co-occurring mental health difficulties, and those with limited support. A history of self-harm is one of the strongest predictors of eventual suicide, even when the individual episodes had no suicidal intent. This is partly because self-harm and suicidality often share underlying risk factors (severe distress, hopelessness, social isolation), and partly because repeated self-harm can erode the person's relationship with their own body and increase the perceived acceptability of more serious self-injury.

The clinical implication is that self-harm warrants serious attention without being treated as identical to suicidality. Someone who self-harms regularly should have their suicidal ideation assessed separately, should have access to safety planning, and should not be dismissed on the grounds that "it's only self-harm". At the same time, treating every episode of self-harm as if it were a suicide attempt is unhelpful, because it imposes a framing that does not match the person's experience and can damage trust.

Pathways to Support

The first step in seeking support is often the hardest, because it requires telling someone. Many people who self-harm have been telling no one for years, sometimes decades. Speaking to a general practitioner is a reasonable starting point in most cases, although the quality of response varies considerably between practitioners. If the response from a particular general practitioner is not helpful, asking to see a different practitioner within the same practice is entirely appropriate, and many practices now have a designated mental health lead who is more familiar with these conversations.

The general practitioner can refer to local mental health services, including primary care psychological therapies (now usually called NHS Talking Therapies in England), specialist self-harm services where available, or community mental health teams for more severe presentations. NHS Talking Therapies typically offers cognitive behavioural therapy, dialectical behaviour therapy skills groups, and trauma-focused approaches, with waiting times that vary by area but typically range from a few weeks to several months.

For under-eighteens, the Child and Adolescent Mental Health Service is the main National Health Service pathway, with school counsellors and pastoral staff often providing the first conversation. The threshold for accessing CAMHS has historically been high, with many young people not meeting criteria for specialist services despite significant distress; this has been a source of substantial criticism of the NHS, and provision varies considerably by region.

For adults, charities including Mind, Rethink Mental Illness, and Self-Injury Support offer information, peer support, and signposting. Self-Injury Support in particular runs a women's self-injury helpline and offers training for professionals. Several specific helplines also exist, including the Samaritans on 116 123, available twenty-four hours a day every day, and Shout, a text-based service, accessed by texting SHOUT to 85258. Both are free and confidential.

Private therapy is also an option for those who can afford it, with the British Association for Counselling and Psychotherapy and the British Psychological Society maintaining registers of accredited therapists. The cost varies considerably by region and therapist seniority, typically from £50 to £150 per session in the United Kingdom, with sliding-scale options available from some practitioners.

Evidence-Based Treatments

Several psychological therapies have evidence for reducing self-harm, and the choice between them depends on the individual's presentation, the underlying difficulties, and what is locally available.

Cognitive behavioural therapy adapted for self-harm focuses on identifying triggers, building alternative coping strategies, and addressing the underlying beliefs that drive the behaviour. Standard programmes typically run for 16 to 20 sessions, with elements including emotion identification, thought records, behavioural experiments, and the development of a personal safety plan. The evidence is strongest for self-harm that is primarily a response to specific situational triggers, particularly in those without complex trauma histories.

Dialectical behaviour therapy, developed by Marsha Linehan for individuals with chronic suicidality and self-harm, teaches a comprehensive set of skills in mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness. The standard programme combines weekly individual therapy with weekly skills training groups over a year, with telephone coaching available between sessions for crisis support. The evidence is particularly strong for those with borderline personality features or chronic recurrent self-harm.

Mentalisation-based treatment focuses on the capacity to understand one's own and others' mental states, which is often disrupted in those who self-harm. The therapy works by repeatedly slowing down emotionally charged moments and inviting curiosity about what was happening in each person's mind. The standard programme combines individual and group therapy over 12 to 18 months.

For young people specifically, family-based interventions have particular evidence, with the family being engaged as a resource for the young person's recovery rather than treated as the problem to be fixed. Developmental group therapy, where young people who self-harm meet in structured groups facilitated by clinicians, also has evidence.

For self-harm that is primarily linked to traumatic experiences, trauma-focused therapies including trauma-focused cognitive behavioural therapy, eye movement desensitisation and reprocessing, and the more recent narrative exposure therapy are appropriate, often delivered after stabilisation work has reduced the immediate frequency of self-harm.

National Institute for Health and Care Excellence guideline NG225, published in 2022, recommends that anyone who has self-harmed should be offered a psychosocial assessment and that, where the self-harm is recurrent, specific psychological therapy should be made available. The guideline also emphasises that staff in any healthcare setting should treat people who have self-harmed with the same care, respect, and privacy as any other patient. The older practice of suturing without anaesthesia or otherwise punishing the patient for their self-harm is explicitly identified as harmful and unacceptable.

Talking to Someone Who Self-Harms

If someone you care about has told you they self-harm, the most useful response is usually not panic, lecture, or demand for an explanation, but warmth, acknowledgement, and a question. Saying something like "thank you for telling me, that took courage, what would help me to understand", communicates that you are willing to bear witness without rushing to fix. Asking "what is the self-harm doing for you", although it may sound odd, often opens a far more useful conversation than asking "why are you doing this", because it presupposes that the behaviour is serving a function rather than being inexplicable.

It can also be useful to ask what the person needs from you, rather than guessing. Some people want practical help with wound care; some want company without conversation; some want a calm presence to sit with through the build-up; some want a regular check-in by text. If the person is in immediate medical danger, that is a different situation, and seeking medical care is appropriate. Outside of acute medical risk, what most people need is to be believed and not abandoned.

Several things are particularly unhelpful and worth avoiding. Demanding that the person stop self-harming, or making your continued support conditional on their stopping, almost always makes the underlying difficulties worse rather than better. Expressing horror, disgust, or panic adds to the shame the person already feels and makes them less likely to talk to you in future. Trying to remove the means of self-harm, while sometimes necessary in acute risk situations, is often counterproductive in the longer term because it does not address the underlying need and can drive the behaviour underground or to more dangerous methods. And dismissing the behaviour as attention-seeking, dramatic, or manipulative, however frustrated you may feel, damages the relationship in ways that are difficult to repair.

If you are a family member or partner, taking care of yourself is also important. Living alongside someone who self-harms is genuinely difficult, and the supporter needs support too. Carer support groups, individual therapy for the supporter, and conversations with mental health professionals about how to manage your own response are all reasonable and useful.

Wound Care and Harm Reduction

For those who currently self-harm and are not yet in a position to stop, basic wound care matters. Keeping wounds clean, watching for signs of infection (increased redness, swelling, heat, discharge, fever), and seeking medical attention when wounds are deep, will not stop, or show signs of infection, are all sensible practices. Many people who self-harm avoid medical care because they fear judgement, but emergency departments are required to provide care without judgement, and most clinicians today have training in compassionate response to self-harm.

The principle of harm reduction, while sometimes controversial, is increasingly recognised as a valid approach in self-harm work. The principle is that, given the person is currently going to self-harm, helping them to do so in less dangerous ways, with attention to wound care and infection prevention, is preferable to insisting on cessation that the person is not yet able to achieve. This approach is consistent with how harm reduction is applied in substance use and other domains.

Recovery Is Real

Self-harm is treatable, and recovery, which can mean either complete cessation or a significant reduction in frequency and severity, is achievable for the great majority of those who engage with appropriate support. Recovery is rarely linear, and setbacks are part of the process rather than evidence of failure. What matters is the direction of travel over months and years, not the precise pattern of any given week or month.

Several factors are associated with better outcomes: engagement with appropriate psychological therapy, addressing underlying difficulties (trauma, comorbid mental health conditions, problematic substance use), the development of alternative coping strategies, the building of a supportive social network, and the practice of self-compassion. These factors compound over time, and many people who self-harmed for years eventually reach a place where the urges are infrequent, manageable, and no longer acted upon.

If you are reading this as someone who currently self-harms, please know that you are not alone, you are not beyond help, and the patterns that have driven this behaviour can change. Reaching out, however small the first step, is the beginning. If the first conversation does not go well, that is not the end of the road; another conversation with a different person, another professional, another service, will often be different. Recovery from self-harm is a long process, and persistence in seeking the right help is itself one of the most important parts of it.
