Self-injury, also called “self-injury,” “self-mutilation,” or simply “cutting,” refers to a variety of behaviors that involve inflicting deliberate harm on oneself that is not usually meant to be a suicidal act.

While some people may unintentionally hurt themselves badly enough to cause death, most people who self-injure do so for other reasons. There are a lot of myths about self-injury, most notably that people who self-injure do so as a means to get attention from other people. This is not usually the case. On the contrary, people who self-injure often do so shrouded in shame and guilt, keeping their secret at all costs.

Generally, it’s believed that self-injury is the result of a person’s inability to use healthy coping strategies when faced with issues of personal identity and finding his or her place in society. There are a lot of reasons why people self-injure and the mixture of emotions that may trigger self-injury are very complicated. Some engage in cutting to cope with emotional pain and distress, especially feelings of self-hatred, worthlessness, loneliness, panic, rejection, confused sexuality, guilt, and sadness. It can be very confusing for someone who does not engage in self-injury to understand this behavior. Through engaging in self-harm, a person may be trying to:

  • Provide a distraction from distressing emotions through physical pain
  • Feel a needed sense of control over his or her body, feelings, and/or life circumstances
  • Punish him or herself for perceived faults
  • Externally express internal emotions
  • Manage and reduce extreme anxiety and distress
  • Feel anything – even physical pain – when he or she feels empty inside
  • Communicate depression and other symptoms of mental illness to the external world

Most carry this burden in secrecy, hiding their self-mutilation behind locked doors, deeply ashamed of their behaviors. Self-injury may help some people cope with their problems, but unfortunately the relief they experience is short-lived. While living with self-injury can make those who engage in this activity feel trapped, with the proper amounts of therapy, medication, and self-care, most people who engage in self-injury are able to recover.

Statistics

Statistics on Self-Injury

As many people who engage in self-injurious behavior tend to keep their habit a secret, the statistics for self-injury are likely skewed. In the United States, each year approximately 2 million cases of self-harm are reported. Most people who cut begin to self-injure in the teen years— 90% of people who engage in this behavior begin during these years. Each year, one in five women and one in seven men engage in some form of self-injury.

What Causes Self-Harm?

Learn About the Causes and Risk Factors for Self-Injury

It’s thought that self-harming behaviors are not the result of one single factor but rather a number of causes and risk factors. The most common causes for self-injury may include the following:

Genetic: Many mental illnesses that can trigger cutting urges, such as borderline personality disorder and depression are thought to have genetic components. People who are born into families that have a history of mental illness are at a greater risk for developing the disorder themselves.

Physical: A great number of mental illnesses lead to imbalances in the levels of certain neurotransmitters in the brain that are involved in emotional regulation. People with these imbalances may self-injure in order to experience any emotions at all. Additionally, physical injury to the body results in a flood of pleasurable chemicals into the body.

Environmental: People who experienced abuse, especially as a child, are at a greater risk for self-injury later in life. These people may not have been able to express their emotions in a healthy way as children and use self-injury as a means to express their overwhelming emotions and cope with the trauma.

Risk Factors:

  • Being female
  • Being in teens and early 20s – most people who cut themselves often begin as teenagers and young adults
  • Having friends who also self-injure
  • Unstable personal identity or sexuality
  • Mental health disorders
  • Drug and alcohol abuse and addiction
