  2. Stress (biology) - Wikipedia

    en.wikipedia.org/wiki/Stress_(biology)

    Physiological stress represents a wide range of physical responses that occur as a direct effect of a stressor causing an upset in the homeostasis of the body. Upon immediate disruption of either psychological or physical equilibrium the body responds by stimulating the nervous, endocrine, and immune systems. The reaction of these systems ...

  3. Psychological stress - Wikipedia

    en.wikipedia.org/wiki/Psychological_stress

    Hans Selye defined stress as “the nonspecific (that is, common) result of any demand upon the body, be the effect mental or somatic.” [5] This includes the medical definition of stress as a physical demand and the colloquial definition of stress as a psychological demand. A stressor is inherently neutral meaning that the same stressor can ...

  4. Chronic stress - Wikipedia

    en.wikipedia.org/wiki/Chronic_stress

    Chronic stress is the physiological or psychological response induced by a long-term internal or external stressor. [1] The stressor, either physically present or recollected, will produce the same effect and trigger a chronic stress response. [ 1 ]

  5. Allostatic load - Wikipedia

    en.wikipedia.org/wiki/Allostatic_load

    The lower the stress levels are in the body, the less likely the allostatic load model will have a significant effect on the brain and health. Although, an increase in stress levels results in an increase in stress on the brain and the health of individuals, making it more likely for the body to have significant effects on homeostasis and cause ...

  6. Social stress - Wikipedia

    en.wikipedia.org/wiki/Social_stress

    Social stress leads to a number of physiological changes that mediate its relationship to physical health. [95] In the short term, the physiological changes outlined below are adaptive, as they enable the stressed organism to cope better. Dysregulation of these systems or repeated activation of them over the long-term can be detrimental to ...

  7. Stressor - Wikipedia

    en.wikipedia.org/wiki/Stressor

    A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism. [1] Psychologically speaking, a stressor can be events or environments that individuals might consider demanding, challenging, and/or threatening individual safety.

  8. Acute stress reaction - Wikipedia

    en.wikipedia.org/wiki/Acute_stress_reaction

    Stress is characterised by specific physiological responses to adverse or noxious stimuli. Hans Selye was the first to coin the term "general adaptation syndrome" to suggest that stress-induced physiological responses proceed through the stages of alarm, resistance, and exhaustion.

  9. Perseverative cognition - Wikipedia

    en.wikipedia.org/wiki/Perseverative_Cognition

    Perseverative cognition is involved with a “stress-disease link". [1] Further, it is the thinking about the stress, or rather the obsessing over it, that establishes a link between stress and disease. Perseverative cognition also focuses on the effects that worrying over anticipated events have on the physical body and mind. [2]
