Document Summary

Stress: a physical, chemical or emotional factor that causes bodily or mental tension and may be a factor in causing diseases, or the physical state of the body to various demands. When we"re stressed it"s our body reacting to stressors (the things that upset or excite us) General adaptation syndrome (developed by selye): our bodies constantly strive to maintain a stable and consistent physiological state (homeostasis) The body attempts to restore homeostasis by an adaptive response. 3 stages of responding to a stressor: Alarm: body responds with changes that temporarily lower resistance. Resistance: if stressor continues, body uses internal resources to try and keep homeostasis i. e. if someone you love is hurt, you try and carry on as normal. Exhaustion: if stress continues long enough, you can"t keep your normal functions. Cognitive-transactional model of stress and coping (lazarus and. 1) trigger a primary appraisal process (individual will perceive event as a threat)
