2. Question: What is the scientific evidence linking stress at work with adverse health?
Stress occurs if a person is exposed to a threatening demand (stressor) that taxes or exceeds her/his capacity of successful response risk of loss of control
Dimensions of stress reactions: • Cognitive appraisal (evaluation of threat)• Affective response (anxiety, anger)• Activation of stress axes in organism (SAM, HPA)• Behavioural reaction (fight or flight) (restricted option!)
Critical for health:• Chronic stressors requiring active coping allostatic load;
risk of stress-related disorders (depression, CHD)
