stressorns
Stressorns are agents or conditions that elicit physiological and psychological stress responses in living organisms. The term covers external stimuli such as environmental hazards, social pressures, or cognitive demands, as well as internal states like inflammation or hormonal fluctuations. In theory, stressorns are defined by their capacity to disrupt homeostasis and provoke adaptive or maladaptive responses.
Stressorns can be acute or chronic. Acute stressorns are short-lived and provoke rapid, high-intensity responses; chronic
Perception of a stressorn engages neural circuits involving the amygdala and prefrontal cortex, triggering the hypothalamic–pituitary–adrenal
Short-term effects include increased vigilance and energy; long-term exposure can contribute to allostatic load, with risks
Researchers quantify stressors by intensity, duration, and frequency, alongside biomarkers such as cortisol levels, heart rate
