Selye's research led him to conclude that when animals are exposed to unpleasant stimuli they display a universal response to all stressors - he called this the General Adaptation Syndrome (GAS).
GENERAL - It is the same response to all agents
ADAPTATION - It's adaptive
SYNDROME - Several symptoms in the stress response
Selye proposed 3 stages that led up to illness which therefore links stress to illness - stress results in depletion of physiological resources, which then lowers resistance to infection.
STAGE 1: ALARM REACTION
Stressor is recognised and a response is made to the alarm. The hypothalamus triggers the prodution of adrenaline from the adrenal glands and causes an adrenaline rush (increased heart rate, sweaty plams ect.), leading to rediness for 'fight or flight'.
STAGE 2: RESISTANCE
