Euphoria (pronounced /juːˈfɔəriə/, from Ancient Greek εὖ, "well", and φέρειν. "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, ecstasy, excitement and joy. Technically, euphoria is an affect, but the term is often colloquially used to define emotion as 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." The word derives from Greek εὐφορία, "power of enduring easily, fertility".
Euphoria is generally considered to be an exaggerated physical and psychological state, sometimes induced by the use of psychoactive drugs and not typically achieved during the normal course of human experience. However, some natural behaviors, such as activities resulting in orgasm, love or the triumph of an athlete, can induce brief states of euphoria. Euphoria has also been cited during certain religious or spiritual rituals and meditation. Euphoria can also be the result of a psychological disorder. Such disorders include "bipolar disorder, cyclothymic personality, head injury, and hyperthyroidism". Euphoria may also occur with "diseases affecting the nervous system, such as syphilis and multiple sclerosis".
