general adaptation system
Hans Selye’s description of what happens when you make strong demands on the body
what are the three stages of general adaptation system?
1) alarm
2) resistance
3) exhaustion
who goes through the three stages of general adaptation system?
everyone when under stress
what does the alarm stage do?
activates the sympathetic nervous system and spends a lot of energy getting ready to fight or flee
when is the resistance stage activated?
when stress acts on someone for a long period of time
what does the resistance stage do?
tries to maintain fight or flight by shutting down other systems in the body (digestion, ovulation, immune system)
what are you more likely to do when you are in the resistance stage?
get sick from things the body should be able to fight off because your immune system is shutting down
what happens when we reach the exhaustion stage?
we can’t keep going because our energy is being used to keep fight or flight activated
what animal makes a good model for studying stress?
baboons because they naturally torture each other and stress each other out, much like western culture
what predicts poor health outcomes in these animals?
rank in their society (lower rank = higher stress)
what physical problems develop in the baboons?
increased heart rate, high blood pressure, weakened immune system
what other problems develop in rhesus monkeys that are under stress?
they develop heart disease and gain weight (mostly around midsection)
do these same effects occur in people?
yes, including type 2 diabetes and heart disease
how do we know that it is stress causing these effects and note lack of health insurance, poor diet, etc.?
