- Developed by Selye
- Stress is a nonspecific response of the body to any kind of demand made upon it (physical, social, psychological)
- Stress can be observed only by the changes it produces in the body
- Occurs with the release of adaptive hormones and changes in the body
- 3 stages-alarm reaction,stage of resistance, stage of exhaustion
Alarm Reaction
alerts the body’s defenses
Shock Phase—full tilt “fight or flight”, cascade of “stress” hormones flood the blood stream
Countershock Phase—recovery and normalization
Stage of Resistance:
body adapts and attempts to limit response to the smallest possible (stress ulcers, stress headaches)
Stage of Exhaustion:
adaptation cannot be maintained, extensive generalized consequences to health, physical exhaustion, death if not “rescued” (learn to cope, reduce the stress, etc)

Homeostasis—alarm—resistance—exhaustion—death or recovery
