Euphoria (/juːˈfɔəriə/; from Ancient Greek εὐφορία, from εὖ eu, "well", and φέρω pherō, "to bear") (semantically opposite of dysphoria) is medically recognized as a mental and emotional condition in which a person experiences intense feelings of well-being, elation, happiness, excitement, and joy.[1]

Technically, euphoria is an affect,[2] but the term is often colloquially used to define emotion and an intense state of transcendent happiness combined with an overwhelming sense of contentment. It has also been defined as an "affective state of exaggerated well-being or elation."[3] The word derives from Greek εὐφορία, "power of enduring easily, fertility".[4][5]
