General Adaptation Syndrome GAS
developed by Hans Selye
Body’s general response to stress.
3 stages:
- Alarm (short, min-hours, fight or flight rising hormones, epinephrine);
- Stage of Resistance (body attempts to adapt and stabilize);
- Stage of Exhaustion (adaptive mechanisms are exhausted and now unable to adapt)
