environmental psychology
the scientific study of environmental effects on behavior and health
fight or flight response
an emotional and psychological reaction to an emergency that increases readiness for action
Adrenocorticotropic (ACTH)
hormone released by the pituitary gland that stimulates the adrenal glands atop the kidneys
HPA (hypothalamic pituitary adrenocortical) axis
brain activation in response to threat and its pathway from the brain to the body
Catehcolamines
epinephrine and norepinephrine released by adrenal glands
- increases sympathetic nervous system activity
- decreases parasympathetic nervous system activity
cortisol
hormone that increases the concentration of glucose in the blood to make fuel available to the muscles and is released by adrenal glands
general adaptation syndrome
a three stage physiological stress response that appears to regardless of the stressor that is encountered
- discovered by Hans Selye
stages of GAS
- alarm phase
- resistance phase
- exhaustion phase
alarm phase
body rapidly mobilizes when confronted with stressor
- fight or flight
- release of stress hormones
resistance phase
body tries to adapt and cope with the stressor by shutting down unnecessary processes such as digestion, growth, and sex drive
exhaustion phase
body’s resistance collapses creating damage that can include susceptibility to infection, tumor growth, irreversible organ damage, or death
telomere
caps at the tips of chromosomes
length of telomeres in people with chronic stress
shorter telomere length due to cortisol
immune system
a complex response system that protects the body from bacteria, viruses, and other foreign substance
glucocorticoids
hormones that flood the brain and wear down the immune system
atherosclerosis
