Mental health is a term used to describe either a level of cognitive or emotional wellbeing or an absence of a mental disorder.[1][2] From perspectives of the discipline of positive psychology or holism mental health may include an individual's ability to enjoy life and procure a balance between life activities and efforts to achieve psychological resilience.[1]
The World Health Organization states that there is no one "official" definition of mental health. Cultural differences, subjective assessments, and competing professional theories all affect how "mental health" is defined
