REHABILITATION OF THE BIOPSYCHOSOCIAL CONCEPT OF EUSTRESS
Eustress concept was less used by researches at the end of XX century and really has disappeared from glossaries of books of Psychosomatics, Health Psychology and Behavioral Medicine. Fortunately, some authors have renewed last years this concept adding other nuances and original peculiarities beneficial for physical and mental health. This paper exemplifies, among these contributions, the strong relation of eustress with immunogenic traits (as self efficiency) and Flow concept, and some humoral markers of eustress (serotonin, oxytocin, endorphins, interferon gamma etc.). Own author’s opinion suggests a strong link between eustress and psychological well being, and underlines the role of eustress as a main component of the new Fava‘s psychotherapy, Well Being Therapy.
