Document Summary
There are 3 separate components to stress the stressors, the stress response and the pathophysiological sequelae that occurs. Stressors can be positive (eustressors) or negative (distressors) or neutral these are stressors that have a neutral effect and they don"t necessarily lead to the stress response until we change them into negative or positive stressors. Stressors can come from a variety of sources including the external environment or personal perception. This non-specific response, whether it is short term or chronic, causes similar hormonal responses. External stimuli are external demands that trigger emotional, behavioural, and physical reactions. These stressors can be categorized by three different factors. First factor is quantity which identifies the negative consequences of stress resulting from an accumulation of stressors either positive or negative in too short a period of time. The next factor is quality and there are three major types for this. You have a major change which affects a large number of people (ex. war).
