Why Do Teens Self-Harm and How Should Parents Respond?

Teens often self-harm to cope with intense emotions they do not know how to manage, not because they want to die, though the behavior can still raise the risk of later suicidal thoughts and deserves a clinical evaluation. A calm, non-punishing response from a parent can make it easier for a teen to accept help. This article explains why teens self-harm, how to talk with them, which signs need emergency care, and what treatment can involve.

Why do teens self-harm?

Self-harm means hurting your own body on purpose, such as cutting, scratching, burning, hitting or picking at skin. MedlinePlus (NIH) describes it as a way some people try to cope with painful feelings, and notes that it is usually not an attempt at suicide (MedlinePlus: Self-Harm). Even so, the behavior is a sign that a teen is in distress and needs support.

No single cause explains it. Several factors can contribute, and the science on exactly how they interact is not fully understood.

Common reasons teens describe

• Relief from overwhelming emotion. Some teens say the physical pain briefly interrupts feelings of anger, shame, panic or emptiness.
• Feeling numb. Others describe self-harm as a way to feel something when they feel disconnected.
• Self-punishment. Teens with harsh self-criticism or low self-esteem may use it to punish themselves.
• Communicating pain. Some teens find it hard to put distress into words, and the behavior becomes a way to show it.
• Peer influence. Exposure to friends who self-harm, or to content online about it, may contribute for some teens.

Why adolescence is a vulnerable stage

MedlinePlus (NIH) describes the teen years as a time of rapid physical, emotional and social change (MedlinePlus: Teen Development). The parts of the brain that help with emotional regulation are still maturing, while school pressure, friendships, identity and family conflict can all be intense. Teens who are already struggling with stress, depression or anxiety may have fewer tools for coping.

Conditions and experiences linked with self-harm

Self-harm is not a diagnosis. It can occur alongside several conditions, and one factor alone does not establish what is going on. A clinician considers the whole picture.

• Depression. Persistent sadness, irritability, loss of interest and changes in sleep or appetite can occur together with self-harm. See MedlinePlus on Teen Depression.
• Anxiety. Anxiety in children can look like stomachaches, avoidance or irritability, and may go unnoticed for a long time.
• Trauma and difficult experiences. Bullying, abuse, losses and other adverse childhood experiences are associated with a greater likelihood of emotional difficulty and strained parenting, as discussed in research on adverse childhood experiences and parenting stress.
• Chronic stress. Ongoing pressure at school, at home or with peers can wear down coping. See MedlinePlus on Stress.
• Behavior and impulse difficulties. Some teens with conditions listed under child behavior disorders also self-harm.

Warning signs parents may notice

Many teens hide self-harm, so signs can be subtle. None of these proves a teen is self-harming, and each can have other explanations.

• Unexplained cuts, scratches, burns or bruises, often on the wrists, arms, thighs or stomach
• Long sleeves or pants worn in warm weather, or reluctance to change clothes around others
• Blood on tissues or clothing, or sharp objects found in unusual places
• Withdrawal from friends and activities, or a drop in grades
• Big changes in mood, sleep or eating
• Statements about worthlessness, hopelessness or being a burden

How to respond when you find out your teen is self-harming

Your first reaction can shape whether your teen talks to you again. Fear, anger and guilt are all normal for a parent, and it can help to take a few breaths before the conversation.

Start with calm and curiosity

• Choose a private, unhurried moment. Sitting side by side, in a car or on a walk, can feel less intense than face to face.
• Say what you noticed and that you care. For example: "I saw the marks on your arm. I'm not angry. I love you and I want to understand what's going on."
• Listen more than you talk. Let silences happen. You do not need to fix everything in one conversation.
• Ask directly about suicide. Asking whether your teen has thoughts of ending their life does not plant the idea. It gives them permission to tell you the truth.

Responses that can make things harder

• Punishing, shaming or threatening consequences, which may push the behavior underground
• Demanding that your teen stop immediately, which can remove a coping tool before a replacement exists
• Treating it as attention-seeking. Even when a teen wants to be noticed, the distress behind it is real.
• Searching your teen's room repeatedly or monitoring constantly, which can damage trust

Research on parenting and adolescent wellbeing suggests that how parents understand and respond to their teen's emotional needs is associated with outcomes such as self-esteem and suicidal behavior, as in this study of parental knowledge and parenting practice among Nepali high school students. These findings come from one setting and show an association, not proof of cause.

Making the home safer

Teens in distress may act on an impulse, so reducing easy access to means can lower risk while treatment gets started. Talk with your teen's clinician about what is right for your family.

• Lock up medicines, including over-the-counter pain relievers such as acetaminophen, and keep only small amounts at home.
• Store firearms unloaded and locked, with ammunition locked separately, or consider keeping them outside the home for now.
• Secure razors, knives and other sharp items your teen has used.

If your teen has had suicidal thoughts, a written plan for hard moments can help. Our article on making a suicide safety plan walks through the steps.

If an overdose or poisoning is possible, call Poison Control at 1-800-222-1222 or 911 right away.

Caring for a wound

Minor cuts and scrapes can often be cleaned with mild soap and water, covered with a clean bandage and watched for signs of infection. MedlinePlus has general guidance on first aid. A deep cut, one that will not stop bleeding with firm pressure, a burn that blisters or covers a large area, or a wound with spreading redness, warmth, swelling, pus or fever needs prompt medical attention. Tell the clinician it was self-inflicted so the visit can include emotional support, not only wound care.

Getting professional help

A pediatrician or family doctor is a reasonable first stop. They can check for injuries, ask about mood, sleep and safety, and refer your teen to a mental health professional. Clinicians combine your teen's history, an interview and sometimes screening questionnaires to understand what is behind the behavior.

What treatment can involve

• Talk therapy. Approaches such as cognitive behavioral therapy and dialectical behavior therapy teach skills for handling strong emotions and urges. Outcomes vary from teen to teen.
• Family involvement. Many programs include parents so the whole household learns how to communicate and support the teen.
• Treating related conditions. If depression or anxiety is present, treatment for those conditions can reduce distress. Some medicines used for these conditions carry a boxed warning on their labeling about increased suicidal thoughts and behavior in children, adolescents and young adults, so the prescriber and pharmacist should explain monitoring. Never start, stop or change a dose without the prescriber.
• Higher levels of care. When safety is a concern, a clinician may recommend intensive outpatient, day programs or a hospital stay.

Helping your teen build other ways to cope

Therapists often work with teens on replacement strategies, though what helps differs from person to person. Some teens find relief with intense exercise, holding ice, drawing, music, writing or calling a friend. These tools are best chosen with your teen and their therapist, and they may take practice. A slip or relapse is common during recovery and does not mean treatment has failed.

Looking after yourself

Parents often feel guilt, fear and exhaustion. Stress and past hardship can make parenting harder, as described in research on parenting stress. Seeing your own clinician or therapist, or leaning on trusted family and friends, can help you stay steady for your teen. Blame is rarely useful: many caring families have a teen who struggles with this.

Screens, social media and peers

Online spaces can be a source of support, and they can also expose teens to content that normalizes self-harm. Research on digital parenting shows that approaches to supervision vary widely and are still being studied. Open conversations about what your teen sees online, and agreed household limits, may work better than secret monitoring. Ask your teen's clinician what approach fits your family.
