Document Summary
Stress: physical, chemical, or emotional factor causing bodily/mental tension and possibly disease; internal state of arousal and physical state of body to different demands. Defined first as non-specific body response to demands; later as pressure per unit area. Strain: ratio of increase/ decrease in length of an object to its original length. Stressors: things that upset or excite us; can be tangible (ie. miss bus, angry friend) or intangible (emotions from competitions or challenges). Acute time-limited stressors: events provoking anxiety (ie. give a talk in public) Brief naturalistic stressors: more serious challenge (meeting deadline for project) Stressful event sequences: natural disaster or traumatic occurrence (death in the family). Stress clears after a while through recognition to move on. Chronic stressors: ongoing demands from life changing circumstances (ie. having a disability from accident, caregiving for one who has alzheimer); no clear endpoint. Distant stressors: past traumatic experiences (ie. child abuse, work in war zone); have continual emotional and psychological impact.
