By the numbers

Many young people go through this.

Self-harm is often hidden, so numbers vary between studies. What they all show is that many young people go through this, and that help is out there.

United States

303.7per 100,000 young people ages 10–24 were treated in emergency departments for self-inflicted injuries in 2015 (CDC study).
18.8% a yearwas how fast those emergency visits rose among girls ages 10–14 from 2009 to 2015 (CDC study).
12–14are the ages when self-harm is most likely to start (Cleveland Clinic).
About 6%of U.S. students ages 12 to 17 said they had anonymously posted hurtful things about themselves online (2016 survey).

World

22.1%of children and teens worldwide had ever self-injured, in a review of studies from 1989 to 2018 covering 686,672 young people.
22.0%of teens in community samples had ever self-injured, in a review of studies from 2010 to 2021.
25.4% vs 22.0%of teen girls and teen boys self-injured in the past year, in a 2022 global review. It affects boys too.

By age

17.2%of teens reported self-injury in community studies (2014 review).
13.4%of young adults reported self-injury in community studies (2014 review).
5.5%of adults reported self-injury in community studies (2014 review).
Behind every number is a young person who deserves care. Getting support early helps, and recovery is possible.

Why the teen years?

A time of big feelings, big changes and big pressures.

If you’re hurting right now, you don’t have to wait. Call or text 988, or text HOME to 741741. If a life is in danger or an injury is serious, call 911.

Teens are the age group most affected by self-harm. It most often begins between about 12 and 14, although it can start earlier or later.

The teenage years bring fast changes in the brain and body, and pressure from school, friends, family and social media. Many young people who self-harm describe feeling overwhelmed, misunderstood, lonely, worthless or empty.

🌊 Feelings that feel too bigSelf-harm can be a way to escape pain for a moment.
Read more

Most self-harm in young people comes from a need to escape strong feelings for a moment, not a wish to die. The relief is short, and the pain underneath comes back, often with shame added on.

The Coping with urges to self-harm guide has safer ways to ride out those moments.
🎛️ Wanting some controlWhen school, family or friendships feel out of your hands.
Read more

Some young people self-harm to feel in control of something when other parts of life feel unmanageable, like family problems or school pressure.

Having a real say in decisions, setting small goals and building routines can give back some healthy control over time.

🪞 Being hard on yourselfFeeling “I deserve this” or “I’m not good enough”.
Read more

Some young people want to punish themselves for something they believe they did wrong. Low self-esteem and harsh self-blame are common.

Nobody deserves to be hurt, including you. The feelings you have are not your fault.
🧱 Pressures that pile upOften it isn’t one big thing.
Read more

Things that can build up

  • Bullying, including online
  • Exams and school pressure
  • Family problems or parents separating
  • Feeling different or left out
  • Grief and loss
  • Questions about sexuality or identity
  • Trauma or abuse

Depression and anxiety often travel alongside self-harm in young people. Getting support for what’s underneath is part of healing.

There is real hope. Most young people who self-harm stop as they move into adulthood. Getting support for the pain underneath still matters, because self-harm that goes on for a long time raises the risk of suicidal thoughts.

Teens who face extra pressure

Some young people carry more, because of how they are treated.

Any young person can self-harm. Some groups face higher rates, mostly because of what happens to them, like rejection, bullying or discrimination. It is never because of who they are.

🏳️‍🌈 LGBTQ+ teensHigher rates, linked to stigma and rejection.
Read more

LGBTQ+ young people have higher rates of self-harm. Experts link this largely to discrimination and rejection, not to who they are.

Acceptance at home, at school and in the community is powerfully protective. The LGBTQ+ mental health guide has more.

LGBTQ+ young people can reach The Trevor Project any time: call 1-866-488-7386 or text START to 678-678.
🪶 Native American and Alaska Native youthA group pediatricians say faces particularly high risk.
Read more

Pediatricians note that Native American and Alaska Native young people who self-harm are at particularly high risk of suicidal thoughts and actions.

Culture, family, community and belonging can be deep sources of strength. Support that respects your culture and community matters.

🚫 Teens who are bullied or left outIsolation and bullying raise risk.
Read more

Children and teens who are bullied, isolated or rejected have higher rates of self-harm. Lacking friends was a common risk factor in a large 2023 review.

If you are being bullied, it is not your fault. Telling a trusted adult or a school counselor is a strong step.

🧢 BoysSelf-harm affects boys too, but they’re often missed.
Read more

In a 2022 global review, about one in five teen boys had self-injured in the past year. All genders, including transgender and non-binary young people, can self-harm.

Boys may be less likely to be noticed or to ask for help. Reaching out is a sign of strength, not weakness.

🧠 Teens with other strugglesDepression, anxiety and other challenges raise risk.
Read more

Depression, anxiety, ADHD, trauma, eating difficulties and substance use all raise the risk of self-harm. Treating both the self-harm and what’s underneath is important.

This doesn’t mean everyone with these experiences self-harms. Only a qualified professional can understand what is going on for you.

Online life

How the internet can hurt, how it can help, and staying safer.

The internet can be a lifeline. It can be easier to talk openly online, and you can find information, advice and people who understand. But there is also a lot of upsetting self-harm content out there that can leave you feeling worse.

🖼️ Running into self-harm contentMost people who see it didn’t go looking for it.
Read more

In a 2018 survey of 729 U.S. adults ages 18 to 29, 43% had seen a self-harm post on one photo-sharing app at least once. Of those, 80% said they came across it by accident, and 59% said it upset them.

People who had seen this content were more likely to report self-harming themselves a month later, even after the researchers took earlier self-harm into account. A study like this can’t prove cause and effect, but it is a good reason to protect your feed.

If you see something upsetting, you don’t have to keep scrolling. Close the app, take a breath, and use one of your coping ideas.
💻 Digital self-harmAnonymously posting mean things about yourself online.
Read more

Digital self-harm means anonymously posting or sharing hurtful things about yourself online. In a 2016 U.S. survey of 5,593 students ages 12 to 17, about 6% said they had done this. Boys reported it more often than girls (7.1% vs 5.3%).

It was more common among teens who had been bullied, had depressive symptoms, used drugs, or had self-harmed offline. Like other self-harm, it is usually a sign of pain underneath, not a joke to brush off.

For parents and teachers: if a young person seems to be targeted by an anonymous account, respond calmly and with care, and keep an open mind about where the posts are coming from.
🧹 Shaping your feedYou have more control over what you see than it may feel.
Read more

Many apps show you more of whatever you pause on, like or search for. That means you can slowly push your feed in a kinder direction. Only follow accounts that make you feel positive and safe.

Ways to take back control

  • Use “not interested” or “hide” on posts that upset you
  • Turn on sensitive-content filters in your settings
  • Report posts that show or encourage self-harm
  • Search for and follow recovery, nature, humour or hobby accounts
  • Set app time limits, especially late at night
🤝 Safer online supportLook for spaces that focus on coping and recovery.
Read more

Online support can help, especially if you feel you can’t talk face to face. The safest spaces are moderated, focus on hope and coping, and don’t allow pictures or detailed descriptions of self-harm.

If a group leaves you feeling worse, more triggered or more hopeless, it is okay to leave. Your wellbeing comes first.

If you need someone right now, call or text 988, or text HOME to 741741. Both are free and open 24/7.
The “My online space check-up” worksheet can help you see which parts of your online life lift you up and which drag you down. The Social media & wellbeing guide has more on healthy tech habits.

Telling an adult

You’re not in trouble. You deserve help.

Many teens fear that if they tell someone, they will be punished, lose their phone, or be watched all the time. A good response focuses on understanding and support, not punishment.

🧑‍🏫 Who you could tellAnyone you trust, at home, school or beyond.
Read more

You could talk to a parent or relative, a teacher, school nurse, school counselor, youth worker, coach, doctor or trained volunteer.

Pick someone who usually listens without judging. It doesn’t have to be a parent first if that feels too hard.

✍️ Ways to say itTalking, writing or texting all count.
Read more

You can write a note, send a message, or practise first. Let them know it may be upsetting, but that you are asking for help.

You could start with

  • “I’ve been having a really hard time and I need help.”
  • “I’ve been hurting myself when things get too much.”
  • “Can you help me see a doctor?”
🩺 Private time with your doctorTeens can talk to a doctor one-on-one.
Read more

Pediatricians recommend that young people have private, one-on-one time with their doctor so they can talk openly. You can ask for this at any appointment.

If someone is at serious risk, professionals may need to share information to keep them safe. You can always ask, “Who will you tell, and what will you tell them?”

🔁 If it doesn’t go wellTry again with someone else.
Read more

If someone reacts badly when you tell them, that says more about them than about you. Your feelings are still valid. Try again with someone else you trust, like a school nurse, doctor or helpline.

You deserve help, not blame. Telling someone is brave.
The Coping with urges to self-harm guide has a “Telling someone” worksheet to help you plan what to say.

School and college

Support is often closer than you think.

Schools and colleges often have their own mental health support and can help connect young people to care. Staff see students every day and can notice when something changes.

🧑‍⚕️ School nurses and counselorsPeople whose job is to help.
Read more

A school nurse, counselor or trusted teacher can listen, help you think about next steps, and help you reach a doctor or mental health support.

You can ask them what they would need to share, and with whom, before you go into detail.

📚 School pressureGrades matter, but you matter more.
Read more

Pressure at school is one of the things young people often name when they talk about self-harm.

It is okay to ask for extra time, a quiet space, or a check-in person at school while you are going through a hard time.

🎓 Starting collegeLeaving home means new stress and new support.
Read more

Self-harm is common among young adults, especially college students. Moving away from home can mean losing your usual support at the same time as facing new stress.

Most colleges have free counseling services. Reaching out there is a strong, sensible step.

🤝 Clubs, teams and belongingFeeling part of something protects.
Read more

Good relationships and feeling that you belong are among the strongest things that protect young people. A club, team, faith group or creative space can help.

Anti-bullying work and inclusive, welcoming schools help everyone feel safer.

Parents and carers: the Supporting someone who self-harms guide has a section on working with school.

Help that works for teens

Talking therapies designed with young people in mind.

A good first step is a doctor or pediatrician, who can listen, check any injuries and help make a care plan. Care usually means talking therapy, plus support with whatever is going on underneath.

⚖️ DBT for teens (DBT-A)The therapy with the best evidence for young people.
Read more

DBT teaches practical skills to manage intense emotions, get through crisis moments and handle relationships. The teen version often includes individual therapy, skills groups with parents, and phone coaching.

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 had the best evidence for reducing repeated self-harm in young people.

🪞 Other talking therapiesCBT, MBT and more.
Read more

Other talking therapies, such as CBT and mentalisation-based therapy, are also offered to young people. For teens, the evidence for these is still less clear, and researchers are working to improve them.

What matters most is finding someone you can trust and talk to honestly.

👨‍👩‍👧 Family involvementHelping the people around you understand.
Read more

Therapy often includes family when that helps. Guidance says families and carers should get clear information and, where appropriate, help with safety planning.

You can tell your therapist what you are and aren’t comfortable sharing with family.

🧰 Help for what’s underneathDepression, anxiety, trauma and more.
Read more

Treating any other mental health struggle alongside self-harm is important. A pediatrician can make a care plan that fits you.

For anything medical, consult with your clinical provider. Whatever treatment you and your provider choose is valid.
The Self-harm: understanding it guide explains what happens at an assessment and what to expect from care.

Everyday things that help

Sleep, screens, people and downtime.

Everyday habits won’t fix deep pain on their own, but they make hard days easier to carry. When you are tired, hungry or alone, feelings hit harder.

😴 SleepTeens need about 8 to 10 hours a night.
Read more

Teens need about 8 to 10 hours of sleep a night. Too much late-night screen time can get in the way.

Keeping phones out of the bedroom at night, if you can, is one of the simplest changes. The Sleep & mental health guide has more.

📱 A family media planScreens that work for you, not against you.
Read more

Social media is not a direct cause of self-harm, but heavy use can disrupt sleep and fuel envy, isolation and self-rejection. Pediatricians suggest a healthy family media plan.

Parents’ screen habits matter too. Time together without phones makes space for conversation and closeness.

🫶 People who get youAt least one trusted person makes a difference.
Read more

Good relationships with family and friends were the protective factor researchers found most often in young people. A supportive parent-child relationship can buffer against hard times.

🛋️ Downtime without guiltRest is not lazy.
Read more

Pediatricians encourage families to ease chronic stress, allow downtime without guilt, and make room for self-care.

Regular meals, movement and time with people you like all help your wellbeing.

Use the “My everyday care plan” worksheet to pick one or two small changes to try this week.

If you’re a parent or caregiver

A short note, and where to find much more.

Finding out your teen self-harms can be frightening. The most helpful things are staying calm, listening more than you talk, and getting your teen to a pediatrician or mental health provider.

Self-harm does not mean your teen wants to die, and it does not make you a bad parent. Teens often deny or hide self-harm at first, so expect some strong reactions and keep the door open.

The Supporting someone who self-harms guide covers what to say, talking with a teen, safety planning, a safer home, working with school and caring for yourself.
