who created the theory of allostasis and the body’s response to chronic stressors
Allostatic load Allostatic load is "the wear and tear on the body" that accumulates as an individual is exposed to repeated or chronic stress.[1] It represents the physiological consequences of chronic exposure to fluctuating or heightened neural or neuroendocrine response that results from repeated or chronic stress.[2] The term was coined by McEwen and Stellar in 1993.[3]
Autonomic nervous system The autonomic nervous system (ANS), formerly the vegetative nervous system, is a division of the peripheral nervous system that supplies smooth muscle and glands, and thus influences the function of internal organs.[1] The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.[2] This system is the primary mechanism in control of the fight-or-flight response.
