Hans Selye created the term as a subgroup of stress [3] to differentiate the wide variety of stressors and manifestations of stress. Eustress is not defined by the stress or type, but rather how one perceives that stressor (e.g., a negative threat versus a positive challenge). Eustress refers to a positive response one has to a stressor, which ...
Hans Selye (1974) proposed four variations of stress. [4] On one axis he locates good stress and bad stress (distress). On the other is over-stress (hyperstress) and understress (hypostress). Selye advocates balancing these: the ultimate goal would be to balance hyperstress and hypostress perfectly and have as much eustress as possible. [5]
The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. [1] [2] Stimuli, like stress, improved memory when it was related to learning the subject. [3] During times of stress, the body reacts by secreting stress hormones into the bloodstream.
Definitions differ, and may be along the lines of continual activation of the stress response, [34] stress that causes an allostatic shift in bodily functions, [3] or just as "prolonged stress". [35] While responses to acute stressors typically do not impose a health burden on young, healthy individuals, chronic stress in older or unhealthy ...
Memory and decision-making can also be negatively affected. [23] Additionally, chronic stress can suppress neural pathways active in cognition and decision-making, speeding up aging. Also, being chronically stressed worsens the damage caused by a stroke and can lead to sleep disorders due to the overexposure of cortisol. [24]
One system suggests there are five types of stress labeled acute time-limited stressors, brief naturalistic stressors, stressful event sequences, chronic stressors, and distant stressors. An acute time-limited stressor involves a short-term challenge, while a brief natural stressor involves an event that is normal but nevertheless challenging.
This model uses cognitive appraisal as a way to explain responses to stressful events. [5]According to this theory, two distinct forms of cognitive appraisal must occur in order for an individual to feel stress in response to an event; Lazarus called these stages "primary appraisal" and "secondary appraisal". [5]
Similarly, when the structural remodeling (e.g., cellular and molecular processes from the nucleus of a cell to the surface of a cell) of neural architecture, which is a key result of stress, continues past the termination of a stressor, the body is no longer maintaining a status of homeostasis and the extended stress response has negative ...
