Catastrophe large scale, often unpredictable events; i. e hurricane, flood, earthquake, fire, war, famine. Flight-or-flight response physiological changes associated with physical exertion. Stress hormones epinephrine and norepinephrine (fast-acting, short-term stress hormone); cortisol (glucocorticoid; slower-acting, relatively long-term stress hormone) Stress response is designed to deal with short term situations very adaptive (can go from rest to very active in a short amount of time: not designed to be long-term, thus can be harmful.

Stress and healing puncture wound study: ppl under exam stress healed 40% slower under; similar results with ppl under marriage stress. Low stress = less likelihood of developing a cold in exposure to the virus/bacteria. Stress and vaccines vaccines are more effective in those with lower stress.
