Definition

Mental health refers to a person's emotional, psychological, and social well-being. It influences cognition, perception, and behavior, determining how individuals handle stress, relate to others, and make choices. Mental health is important at every stage of life, from childhood and adolescence through adulthood.

Key Components

Mental health encompasses several interconnected domains: emotional well-being (the ability to manage feelings and cope with challenges), psychological well-being (a sense of purpose, personal growth, and self-acceptance), and social well-being (positive relationships and community connection). The World Health Organization defines mental health as 'a state of well-being in which the individual realizes their own abilities, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to their community.'

Mental Health vs. Mental Illness

Mental health and mental illness are related but distinct concepts. Mental health exists on a continuum — a person can have poor mental health without meeting criteria for a diagnosed mental illness, and someone with a diagnosed condition can experience periods of good mental health with appropriate treatment and support. Factors that contribute to mental health include biological factors (genetics, brain chemistry), life experiences (trauma, abuse), and family history of mental health conditions.
