Stress Definition
When an individual perceives that the environmental demands tax or exceed their adaptive capacity
211
General Adaptation Syndrome to Stress
- Chronic stress = contributor to disease bc cortisol suppresses immune system
- People have same physical response to all types of prolonged stress
- 3 stages:
1. Alarm (physiological, FFF)
2. Resistance (prolonged stress): pituitary release ACTH = adrenal cortex releases cortisol. Increases blood glucose levels, metabolism of fats and proteins
3. Exhaustion: pituitary and adrenal lose capacity to maintain elevated hormone levels and physical reserves are depleted. Leads to: mental/physical exhaustion, illness, collapse, death
212
Transactional Model of Stress
- Events are not inherently stressful or nonstressful, but its how we appraise the event
1. Primary appraisal: relevance of event to wellbeing based on values, beliefs. May be irrelevant (no stress), positive (no stress) or challenging (stress...second appraisal)
2. Secondary appraisal: are my resources/abilities sufficient to cope with this threatening situation? If yes, no stress response. If no, stress response.
3. Cognitive reappraisal: monitors situation and uses new info to modify primary/secondary appraisals. This can increase or decrease the stress response
