Why Mental Health Vocabulary Matters
Mental health conversations are more common than ever — in clinics, workplaces, schools, and everyday life. Yet the language used can feel technical, inconsistent, or confusing. A therapist might refer to dysregulation; a workplace program might mention psychological safety; a friend might describe burnout. Without a shared understanding of these terms, it is harder to seek help, communicate effectively, or evaluate information critically.
This plain-language reference defines the core terms you are most likely to encounter. It is organized to build understanding progressively — from foundational concepts to terms used in therapy and recovery. For a parallel resource covering nutrition language, see our nutrition glossary.

Mental Health
A state of emotional, psychological, and social well-being that influences how a person thinks, feels, and behaves. Mental health exists on a spectrum and can change over time; it is not simply the absence of a diagnosable condition.
Anxiety
A natural response to perceived threat or uncertainty, characterized by worry, tension, and physiological arousal. When anxiety is persistent, disproportionate to the situation, or significantly disrupts daily life, it may indicate an anxiety disorder requiring professional evaluation.
Depression
A mood disorder involving persistent low mood, loss of interest in previously enjoyable activities, and a range of cognitive and physical changes. Depression is a recognized medical condition with evidence-based treatments; it is not a character flaw or a sign of weakness.
Burnout
A state of chronic stress leading to physical and emotional exhaustion, detachment, and reduced effectiveness — most commonly associated with prolonged workplace or caregiving demands. The World Health Organization classifies it as an occupational phenomenon, not a medical diagnosis.
Resilience
The capacity to adapt, recover, and maintain functioning in the face of adversity, stress, or trauma. Resilience is not a fixed trait but a dynamic process that can be supported through relationships, coping skills, and social environments.
Nervous System Regulation
The process by which the autonomic nervous system returns to a balanced, calm state after a stress response. Practices such as slow breathing, movement, and social connection are commonly used to support regulation, though individual responses vary.
Trauma
An emotional response to a deeply distressing or disturbing event that overwhelms an individual's ability to cope. Trauma can be acute (a single event), chronic (repeated exposure), or complex (prolonged interpersonal harm), and its effects vary widely between individuals.
Coping Strategy
A conscious or habitual behavior, thought, or action used to manage stress or difficult emotions. Coping strategies range from adaptive (exercise, social support, problem-solving) to maladaptive (avoidance, substance use), with different outcomes for long-term well-being.
Psychotherapy
A structured, evidence-based form of treatment in which a trained mental health professional helps a person explore thoughts, feelings, and behaviors to reduce distress. Common approaches include cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and interpersonal therapy (IPT).
Mindfulness
The intentional practice of paying attention to the present moment — thoughts, sensations, and feelings — without judgment. Mindfulness-based interventions have a growing evidence base for supporting stress reduction and emotional regulation.
Psychological Safety
A shared belief within a group or organization that members can speak up, take risks, or express concerns without fear of punishment or humiliation. Research associated with organizational psychologist Amy Edmondson identifies it as a key factor in team performance and well-being.
Self-Efficacy
A person's belief in their own ability to perform specific behaviors or achieve particular outcomes. Introduced by psychologist Albert Bandura, self-efficacy influences motivation, resilience, and the likelihood of adopting and sustaining health-related behaviors.

These Definitions Are Educational, Not Diagnostic
Understanding a term does not mean you can apply it to your own or another person's condition. Mental health diagnoses require comprehensive evaluation by a qualified professional. If any of these concepts resonate with your own experience in a concerning way, speaking with a licensed mental health provider is the appropriate next step. In a crisis, contact a crisis helpline or emergency services.
