  2. Stress (biology) - Wikipedia

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

    Stress management encompasses techniques intended to equip a person with effective coping mechanisms for dealing with psychological stress, with stress defined as a person's physiological response to an internal or external stimulus that triggers the fight-or-flight response. Stress management is effective when a person uses strategies to cope ...

  3. Behavioural responses to stress - Wikipedia

    en.wikipedia.org/.../Behavioural_responses_to_stress

    A study about stress effects on female songbird’s response to sexual signal for mating indicated that the response to this specific signal can be impaired if the female is exposed to developmental stress. Behavioural changes as a result from developmental stress impairs neural responses to sexual signals, which reduces mating. [5]

  4. 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 ...

  5. Stressor - Wikipedia

    en.wikipedia.org/wiki/Stressor

    Stress hormones travel in the blood stream to relevant organs, e.g., glands, heart, intestines, triggering a flight-or-fight response. Between this flow there is an alternate path that can be taken after the stressor is transferred to the hypothalamus , which leads to the sympathetic nervous system ; after which the adrenal medulla secretes ...

  6. Fight-or-flight response - Wikipedia

    en.wikipedia.org/wiki/Fight-or-flight_response

    A typical example of the stress response is a grazing zebra. If the zebra sees a lion closing in for the kill, the stress response is activated as a means to escape its predator. The escape requires intense muscular effort, supported by all of the body's systems. The sympathetic nervous system's activation provides for these needs. A similar ...

    The stress response — “characterized as a rapid adaptive process to actual or perceived danger,” as the researchers note in their paper — can significantly affect circadian rhythm, ...

  8. 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 ]

  9. Allostatic load - Wikipedia

    en.wikipedia.org/wiki/Allostatic_load

    A typical allostatic response has been initiated by a stressor and then continues for the duration of the stressor, in which it shuts off as the stressor has ended. Allostatic load is the accumulation of stressors and maladaptive responses that may result in an extreme state, where the stress response does not terminate. [26]
