Much of the research on eustress has focused on its presence in the workplace. In the workplace, stress can often be interpreted as a challenge, which generally denotes positive eustress, or as a hindrance, which refers to distress that interferes with one's ability to accomplish a job or task.
The estrous cycle (from Latin oestrus 'frenzy', originally from Ancient Greek οἶστρος (oîstros) 'gadfly') is a set of recurring physiological changes induced by reproductive hormones in females of mammalian subclass Theria. [1]
The term was coined by McEwen and Stellar in 1993. [2] The term is part of the regulatory model of allostasis, where the predictive regulation or stabilization of internal sensations in response to stimuli is ascribed to the brain. [3] Allostasis involves the regulation of homeostasis in the body to decrease physiological consequences on the body.
He started to use the term to refer not just to the agent but to the state of the organism as it responded and adapted to the environment. His theories of a universal non-specific stress response attracted great interest and contention in academic physiology and he undertook extensive research programs and publication efforts. [74]
(For a factor A with two levels, scaled so that low = -1 and high = +1, the effect of A has a mean-unbiased estimator that is evaluated by subtracting the average observed response when A is -1 from the average observed response when A = +1 and dividing the result by 2; division by 2 is needed because the -1 level is 2 scaled units away from ...
János Hugo Bruno "Hans" Selye CC (/ ˈ s ɛ l j eɪ / [dubious – discuss]; Hungarian: Selye János Hungarian pronunciation:; January 26, 1907 – October 16, 1982) was a pioneering Hungarian-Canadian endocrinologist who conducted important scientific work on the hypothetical non-specific response of an organism to stressors.
Hans Selye defined stress as “the nonspecific (that is, common) result of any demand upon the body, be the effect mental or somatic.” [5] This includes the medical definition of stress as a physical demand and the colloquial definition of stress as a psychological demand. A stressor is inherently neutral meaning that the same stressor can ...
The term "hormesis" derives from Greek hórmēsis for "rapid motion, eagerness", itself from ancient Greek hormáein to excite. [4] The same Greek root provides the word hormone. The term "hormetics" is used for the study of hormesis. [6] The word hormesis was first reported in English in 1943. [4]
