Self-harm: understanding it
Self-harm is a sign of deep pain, not a flaw. Understanding it is the first step towards kinder ways through, and recovery is real.
By the numbers
You are far from alone.
Self-harm is often hidden, so numbers vary between studies. What they all show is that many people go through this, and help is out there.

What is self-harm?
A way of coping with feelings that feel too big to hold.
Self-harm means hurting your own body on purpose. Most often, people who self-harm do not want to die. They are trying to cope with emotional pain that feels overwhelming, like a pressure cooker letting off steam.
You may also hear it called “self-injury” or “non-suicidal self-injury”. Doctors in many countries also count any intentional self-injury or self-poisoning as self-harm, whatever the reason behind it.
Self-harm does not always look obvious. Some harmful behaviours may not feel like self-harm at first, and many people keep it very private. It can affect anyone, of any age, gender or background.
The relief self-harm brings is usually short. Afterwards, feelings like guilt and shame can build up, and the pain underneath is still there. Over time this can turn into a cycle that is hard to break on your own.
Why people self-harm
The pain underneath, and what self-harm is trying to do.
There is no single reason. The reasons can come from past or present experiences, can change over time, and are different for everyone. Sometimes a person isn’t sure why they do it.
Researchers who looked at many studies found the most common pattern is this: strong painful feelings come first, and self-harm brings brief relief from them. Many people also describe self-harm as a way to punish themselves.

This is the most common reason. When feelings build up and there seems to be no other outlet, self-harm can feel like a release valve. It can briefly ease tension or panic, or distract from emotional pain.
The trouble is that the relief fades quickly and the feelings come back, often with shame added on top. Learning other ways to ride out big feelings is a key part of recovery.

Some people self-harm to feel a sense of control when other parts of life feel unmanageable, such as family problems, school or work pressure, or things that happened to them.
Finding healthy ways to take back some control, like setting small goals, having a say in decisions, or building routines, can help over time.
Read more
Low self-esteem and harsh self-blame are common. Some people turn anger or disappointment inward, towards themselves. Research supports self-punishment as one of the main reasons people give.
A therapist can help you notice that harsh inner voice and slowly build a kinder one. Nobody deserves to be hurt, including you.

Some young people describe feeling empty, lonely or worthless, and self-harm briefly changes that feeling. Others want a short escape from distress.
Numbness is often the mind’s way of protecting itself after too much stress or hurt. Therapy can help you reconnect with your feelings safely, a little at a time. See the “Trauma: what it is & how it affects you” guide if this sounds familiar.

Sometimes self-harm is a way of showing distress, or a call for help. That is not “attention-seeking” in a bad way. Wanting people to notice that you are struggling is completely understandable.
Many people who self-harm hide it carefully. Whether someone hides it or not, the message underneath is the same: “I am in pain and I need care.”
Pressures that can build up
- Bullying, including online
- Pressure at school or work
- Family or relationship problems
- Money worries
- Grief and loss
- Abuse, trauma or discrimination
- Confusion or stress about sexuality or identity
- Stress, anxiety, depression or low self-esteem
- Feeling misunderstood, overstimulated or lonely
Often it isn’t one big thing but many smaller pressures piling up over time. Self-harm is also more common alongside experiences like depression, anxiety, eating difficulties, trauma, substance use, ADHD and autism.
Risk and protective factors
What raises the chance of self-harm, and what helps protect.
Researchers talk about “risk factors”, which make self-harm more likely, and “protective factors”, which make it less likely. A risk factor is not a prediction. Plenty of people face many of them and never self-harm, and anyone can struggle.
A 2023 review that pulled together 61 earlier reviews of young people found the same risk factors coming up again and again. It also found that far less research has looked at what protects people, which is why protective factors deserve more attention.

Childhood abuse, trauma, bullying, parents separating and difficult family relationships were among the most common risk factors researchers found in young people.
Self-harm is more common among people with a history of trauma or abuse. When pain has nowhere else to go, the body can become the place where it shows up.
Read more
In the 2023 review, depression and anxiety were among the factors with the strongest evidence of a link to self-harm. Substance use also came up often.
Cleveland Clinic also lists experiences like autism, eating difficulties, trauma responses, sleep problems and intense mood changes as linked to self-harm. Getting support for what’s underneath is part of healing.
This doesn’t mean everyone with these experiences self-harms, or that self-harm means someone has a particular condition. Only a qualified professional can understand what is going on for a person.
Read more
People who feel isolated or rejected have higher rates of self-harm. Lacking friends was one of the common risk factors in the 2023 review.
Being around others who self-harm, in person or online, is also linked to a higher chance of self-harming. That is not anyone’s fault. It is one more reason why safe, supportive company matters.
Read more
Lesbian, gay, bisexual and queer people have higher rates of self-harm. The review authors advise professionals to pay particular attention to young people who are LGB.
The risk comes from how people are treated, not from who they are. Acceptance at home, at school and in the community is powerfully protective. The LGBTQ+ mental health guide has more.

A 2019 review of 48 studies found that people who find it hard to manage their emotions had roughly two to three times the odds of self-injuring. This link held across settings, ages and sexes.
The strongest links were with feeling there are few ways to calm down, being hard on yourself for having feelings, and acting on impulse when upset. The good news: these are skills that can be learned. See “Building emotion skills” in the Coping with urges to self-harm guide.

Good relationships with family and friends were the protective factor researchers found most often.
Things that help protect
- At least one trusted adult or friend to talk to
- Feeling accepted for who you are
- A school, team, club or faith group where you belong
- Knowing where to get help, and being able to reach it
- Kinder ways to cope with big feelings
- Being gentle with yourself
Signs to notice
Gentle clues that someone may be struggling.
People who self-harm often hide it, so the signs can be easy to miss. Changes in mood and behaviour can matter as much as anything you can see.
Read more
Someone may stay covered up all the time, even in warm weather, or find reasons to avoid activities where skin is visible. They may give vague explanations for marks or injuries.
Of course, people cover up for lots of reasons, including comfort, culture, faith or body image. One sign on its own doesn’t tell you much. Look at the bigger picture.
Read more
Repeated injuries with no clear explanation can be a sign. The person may seem uncomfortable or change the subject if you ask.
Read more
Signs of depression, like low mood, tearfulness, losing interest in things, sleep changes or low energy, are common. Some people have outbursts of anger or argue more.
You may also notice self-blame, feeling worthless, or saying things like “I’m not good enough”.
Read more
Withdrawing from people and avoiding conversations can be a sign that someone is carrying something heavy. They may spend long periods alone in their room or the bathroom.
Staying in gentle contact matters, even if they don’t want to talk yet. A text, a snack, or sitting together quietly can say “I’m here”.
Read more
Talk of ending things or not wanting to go on is a sign to act straight away. Take it seriously every time, even if it is said casually.
Asking honestly and lovingly about suicide is far more likely to help keep someone safe than to put the idea in their head.
Self-harm and suicide
Different, but related. Always take self-harm seriously.
Most self-harm is not an attempt to die. Many people describe it as a way of surviving very hard feelings. So self-harm and suicide are not the same thing.
But they are linked. People who self-harm have a much higher risk of suicide, and when self-harm goes on for a long time, the risk of suicidal thoughts rises. That is why even small amounts of self-harm deserve care and attention.
Some people who self-harm also have thoughts of suicide at times. Those thoughts can come and go. Getting support early, and having a safety plan ready, makes a real difference.
Myths and facts
Clearing up what people often get wrong.
Read more
People self-harm for many reasons, and many keep it secret. Calling it attention-seeking makes people feel ashamed and less likely to ask for help.
If someone does want people to notice they are struggling, that is a very human need. They deserve care, not judgement.
Read more
Brushing self-harm off as “just puberty” or “a phase” can leave a young person feeling dismissed. Self-harm is a sign that something else is going on.
Getting help early, before things reach crisis point, is better for everyone.
Read more
Self-harm is often talked about in teen girls, but it affects people of every gender, including non-binary and transgender people, and adults of all ages.
Boys and men may be less likely to be noticed or to ask for help. Everyone deserves to be asked kindly how they are doing.

How visible or serious an injury looks doesn’t tell you how much someone is hurting inside. Even small amounts of self-harm can be a sign of a lot of pain.
Read more
Most people who self-harm are not trying to end their life. But the two are linked, so always take self-harm seriously and ask gently about suicidal thoughts.
Read more
Pressuring someone to stop, or threatening to take away their independence, can increase shame and push self-harm further into hiding.
What helps is listening, understanding the feelings underneath, and getting support to learn new ways of coping.
Read more
Pediatricians list this as one of the most common myths they hear. Asking directly, calmly and with love shows someone it is safe to talk.
The same is true for suicide: asking honestly about it is far more likely to help keep someone safe than to give them the idea.
Read more
Most young people who self-harm stop as they move into adulthood. That is real hope. But the pain underneath still deserves care, and self-harm that goes on for a long time raises the risk of suicidal thoughts.
Treating both the self-harm and whatever is going on underneath, like depression or anxiety, is important.
Read more
Treatment is available, and both physical and emotional recovery is possible. Many people find other ways to cope and go on to live full lives.
Self-harm at every age
It can affect anyone, of any age or gender.
Self-harm most often begins in early adolescence, between about 12 and 14. It is also common among young adults, especially college students. But it can start at any age, and many adults live with it quietly.
Read more
Teens are the age group most affected by self-harm. Fast changes in the brain and body, plus pressure from school, friends, family and social media, can leave young people feeling overwhelmed or alone.
There is real hope here too. Most young people who self-harm stop as they move into adulthood, especially when they have support.
Read more
Adults self-harm too, sometimes for the first time later in life and sometimes after years of keeping it private. Money worries, relationship problems, grief, illness, work stress and contact with the justice system can all play a part.
Adults may feel extra shame because self-harm is seen as a “teen thing”. It isn’t. Talking therapies work for adults, and it is never too late to get support.
Read more
Self-harm is often talked about in girls, but boys and men self-harm too. In a 2022 global review, about one in five teen boys had self-injured in the past year.
Boys and men may be less likely to be noticed or to ask for help. Everyone deserves to be asked kindly how they are doing.
Read more
People of every gender, including transgender and non-binary people, can self-harm. Self-harm also crosses every culture, faith and income level.
Some groups face higher rates because of how they are treated, such as rejection, discrimination or bullying, not because of who they are.
What to expect from care
What happens when you reach out to a doctor or mental health team.
Not knowing what will happen can stop people from asking for help. Knowing the usual steps can make that first visit feel less scary.
The usual steps
- You talk to a doctor, school nurse or counselor. They listen, check any injuries and talk about options.
- They may refer you to a mental health team for an assessment, a longer conversation about what is going on.
- You and the team agree a care plan together, setting out the support you need and how you will get it.
- You start support, such as talking therapy, and get contact details for help in an emergency.
Read more
There is no test for self-harm. Instead, a professional will talk with you about what has been happening, how you feel, and what is going on in your life, such as money worries, grief, school trouble, bullying or a breakup.
You may be asked about
- What led up to the self-harm and how you felt afterwards
- Your relationships and where you live
- Anything you have already tried that helped
- Any injuries that need care
- Whether you have thoughts of ending your life
- Alcohol or drug use
Read more
Depending on what you need, you might meet a social worker, an occupational therapist, a counselor, a mental health nurse, a psychiatrist, or a psychologist or therapist.
If what’s underneath includes grief, abuse, sexual assault or eating difficulties, you may be connected with a specialist service for that too.
Read more
A trained therapist will keep what you tell them about your feelings and experiences confidential. Teens can ask for private time with their doctor.
If someone is at serious risk, professionals may need to share information to keep people safe. You can always ask, “Who will you tell, and what will you tell them?” at the start.
Read more
If the first person you speak to doesn’t help, your feelings are still valid. You can try other support, like a school nurse, a different doctor or a helpline.
You are allowed to ask questions about your care, to bring someone with you, and to say if something isn’t working.
Therapies that help
Talking therapies teach new ways to cope.
Getting help can reduce the chance of self-harm continuing. Care usually means talking therapy plus support with whatever is going on underneath, like stress, trauma, depression or family problems.
A good first step is to see a doctor, who can listen, check any injuries and connect you with mental health support. You and your care team can then agree a plan together.

DBT teaches practical skills to manage intense emotions, get through crisis moments, and handle relationships. Self-harm is one of the main things it was designed to help with.
The teen version (DBT-A) often includes individual therapy, skills groups with parents, and phone coaching for both young people and parents.
In a major U.S. study of teens at high risk, self-harm was about one-third as likely after six months of DBT as with a comparison therapy. A large research review found DBT-A was the therapy with the best evidence for reducing repeated self-harm in young people.

CBT helps you spot painful thinking patterns, understand what triggers urges, and practise new ways to solve problems and respond to stress.
For adults, research shows CBT-based therapy can reduce repeated self-harm, with benefits seen 6 and 12 months later. Health guidance recommends short, person-centred CBT-informed therapy for adults who self-harm.
For young people, the evidence for CBT on its own is less clear so far, and researchers are working to adapt it.
Read more
MBT helps people understand what is going on in their own minds and in other people’s, especially in close relationships. This can make big feelings less confusing and less overwhelming. It is one of the talking therapies offered to young people who self-harm.
For adults, research found positive effects on repeated self-harm. For teens, the evidence is still uncertain, and more studies are needed.
Read more
Therapy can include family or a partner when that helps. Guidance says families and carers should get clear information and, where appropriate, help with safety planning.
You get a say in who is involved. The Supporting someone who self-harms guide is a good place for loved ones to start.
Read more
Depending on what is going on, you may also see a counsellor, social worker, psychologist or specialist service, such as support for grief, abuse or eating difficulties.
Care should not be withheld because of a diagnosis or because someone also uses alcohol or drugs.
When and where to get help
Where to turn, today and every day.
Reach out for support if…
- Urges feel stronger or harder to resist
- You are having thoughts of suicide
- You are self-harming or thinking about it
- You feel hopeless, numb or alone most of the time
- You have an injury that needs checking
- You’re worried about someone else
Asking for help with self-harm is no different from getting care for a physical health problem. Getting support can lower the chance that self-harm continues.
