Recent Developments in Driver Control Theory: from Task Difficulty Homeostasis to Risk Allostasis

18) It is a concept that refers to the "wear and tear" of allostasis
(the body's protective stress response) on the body.
is the ability to maintain the dynamic stability of the physiological systems facing a constantly changing environment (environmental stress or allostatic load).
This dysfunction is one characteristic symptom of allostasis
In fact, the principle of allostasis
, which plays a central role in Koob and LeMoal's (2001) theories on addiction also plays an integral role in McEwen and Wingfield's (2010) and other scientists' perspectives on the development of stress-related mood and anxiety disorders.

and Allostatic Load," Annals of the New York Academy of Sciences 840 (1998): 33-44: and "Sleep Deprivation as a Neurobiologic and Physiological Stressor: Allostasis
and Allostatic Load.
4) According to the theory of allostasis
, the vulnerability and total damage caused to person who is exposed to stress is a combination of past traumatic experiences and the current traumatic conditions (1) stress load.
was suggested as an alternative to homeostasis when
Chronic stress, however, can cause the body to maintain a different baseline state, called allostasis
is beneficial in the sense of self-preservation, but if taken to an extreme, it begins to tear down the body's defenses and leaves the door open for illness.

As McEwen later described it, allostatic load is "the price the body pays for being forced to adapt to adverse psychosocial or physical situations, and it represents either the presence of too much allostasis
or the inefficient operation of the allostasis
response systems, which must be turned on and then turned off again after the stressful situation is over.
