Euphoria, 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 eforia, 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. These include bipolar disorder, cyclothymia and hyperthyroidism and can also result from a head injury. Euphoria may also occur with, "diseases affecting the nervous system, such as syphilis and multiple sclerosis."
