Mental health is often mistakenly equated with the absence of mental illness. However, mental health refers to a person's overall emotional, psychological and social well-being. It influences how individuals think, feel and behave, and how they cope with stress, relate to others, and make choices. Mental illness, on the other hand, refers to diagnosable conditions - such as depression, anxiety disorders or schizophrenia - that disrupt a person's thoughts, mood, behaviour or functioning. It is possible for individuals with mental illness to experience periods of good mental health, just as people without a mental illness may struggle with poor mental well-being at times.

According to the World Health Organization (WHO), it is a "state of well-being in which the individual realizes his or her abilities, can cope with the normal stresses of life, can work productively and fruitfully and can contribute to his or her community".

From the perspectives of positive psychology or holism, mental health may include an individual's ability to enjoy life and to create a balance between life activities and efforts to achieve psychological resilience. Cultural differences, personal philosophy, subjective assessments and competing professional theories all affect how one defines "mental health". Some early signs related to mental health difficulties are sleep irritation, lack of energy, lack of appetite, thinking of harming oneself or others, self-isolating (though introversion and isolation are not necessarily unhealthy), and frequently zoning out.
