What is stress?
stress
a holistic transaction between the individual, a stressor, and the environment, resulting in a stress response
holistic transaction
a stress appraisal process involving the potential stressor, the individual, and the environment; an individual’s appraisal process is influenced by his or her level of well-being and ability to cope with the potential stressor at the moment under the specific environmental conditions surrounding the person and the potential stressor
stressor
any stimulus appraised by the individual as threatening or capable of causing harm or loss
stress response
a set of physiological adaptations of the body to regain homeostasis in the face of threat, harm, or loss
milieu interieur
the body’s internal environment
endocrinologist
a person who studies the anatomy and physiology of the endocrine system and the treatment of endocrine problems
noxious
harmful, injurious, or detrimental to health
General adaptation syndrome (GAS)
the three-phase stress response identified by Selye. Alarm, resistance, and exhaustion
Alarm phase
the first phase of GAS, in which the body mobilizes energy to meet the demands of stressors
resistance phase
the second phase of GAS, in which the body attempts to maintain homeostasis in the face of chronic stressors
exhaustion phase
the third phase of GAS, in which a body part or system breaks down as a result of the energy demands of chronic stressors
strain
the wear and tear on body parts and systems as they fight to maintain homeostasis in response to stressors
adaptation energy
the body’s finite energy reserves available for coping with stressors
fight or flight
the state of physiological readiness for action created by the body during the alarm phase
weak links
susceptible body parts or systems that break down under the wear and tear of chronic stressors
