Suicide is a public health priority that affects people of all ages and backgrounds. This guide explains what suicide is, how common it is, and why people may come to consider it. You will learn evidence-informed risk and protective factors, recognized warning signs, and practical steps to help someone in crisis. We also outline how to access immediate support, build safety plans, and find culturally responsive care. The information here is intended to be a durable resource for understanding suicide and strengthening community response.
What Suicide Is and How Common It Is
Suicide is when someone intentionally ends their own life. It is often the result of untreated or under-treated mental health conditions, usually in combination with overwhelming stressors and limited access to support. Globally, suicide is a leading cause of death, with higher rates among certain age groups and marginalized populations. Many more people attempt suicide but survive; these non-fatal attempts still signal serious distress and risk. Understanding basic epidemiology helps schools, workplaces, and health systems prioritize prevention resources where they are needed most.
Risk and Protective Factors at a Glance
Risk factors raise the likelihood of suicide, while protective factors reduce it. No single factor causes suicide; rather, combinations of personal, social, and environmental influences accumulate over time. Recognizing these patterns helps communities screen, identify needs, and intervene early.
Key Risk Factors
- Mental health conditions such as depression, bipolar disorder, schizophrenia, and substance use disorders
- A personal history of suicide attempts or self-harm
- Chronic pain, serious illness, or recent medical crises
- Family history of suicide or childhood abuse or neglect
- Social isolation, unemployment, financial stress, and major life transitions
Key Protective Factors
- Connectedness to family, friends, and community
- Access to mental health care and crisis services
- Strong cultural or religious beliefs that discourage self-harm
- Problem-solving skills and help-seeking behavior
- Restrictive access to means, especially firearms
Warning Signs and How to Respond
Recognizing warning signs can help you offer timely support. Signs may include talking about wanting to die, increased substance use, withdrawal from others, extreme mood swings, and giving away possessions. If you observe these signs, take them seriously, ask directly about suicide, and encourage professional help. Immediate responses can include staying with the person, removing means, and contacting crisis services.
Immediate Support and Crisis Services
In many countries, crisis lines and emergency numbers provide free, confidential support 24/7. Mobile text or chat services can be useful when voice calls are difficult. Healthcare providers can conduct assessments and recommend treatment options such as therapy, medication, or intensive outpatient care. Quick access to evidence-based interventions reduces immediate risk and supports longer-term recovery.
Safety Planning and Clinical Care
What a Safety Plan Includes
A written safety plan identifies personal warning signs, internal coping strategies, people to contact, and professional resources. It can be created in clinical settings or at home and shared with trusted allies. Research suggests that having a concrete plan reduces suicidal thoughts and increases help-seeking. Safety plans should be revisited when life circumstances or treatment needs change.
Clinical Treatments That Help
- Therapies such as Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and Collaborative Assessment and Management of Suicidality (CAMS)
- Medications for underlying conditions like depression or bipolar disorder, when indicated
- Integrated care for co-occurring substance use and mental health conditions
Prevention Approaches at Community and Policy Levels
Public health strategies include media guidelines that avoid harmful details, means restriction such as safe storage of firearms and medications, and gatekeeper training for schools and workplaces. Surveillance, data-informed planning, and culturally responsive outreach help address disparities. Partnerships between health systems, communities, and governments create comprehensive safety nets.
