    The human body shows differentiated endocrinal and hemodynamic responses to various psychological and physical stressors, challenging Cannon's "alarm reaction" theory. This study investigated cardiovascular and hormonal changes during stress. Keywords: stress response, cardiovascular, endocrinal, hemodynamic.

    Area of Science:

    • Cardiovascular Physiology
    • Endocrinology
    • Human Physiology

    Background:

    • Cannon's "alarm reaction" theory posits a uniform physiological response to diverse stressors.
    • Understanding differentiated stress responses is crucial for cardiovascular health and stress management.
    • Previous research often focused on single stressors, limiting insights into complex responses.

    Purpose of the Study:

    • To investigate the differentiated endocrinal and hemodynamic responses to various psychological and physical stressors.
    • To compare these differentiated responses against the generalized "alarm reaction" model.
    • To assess specific physiological parameters during and after stressor exposure.

    Main Methods:

    • Assessed endocrinal (arginine vasopressin, renin) and hemodynamic parameters in 5 patients.

  • Utilized a confusion color chart, cold pressure test, and isometric hand ergometer stress.
  • Measured parameters during adaptation, stress, and recovery phases.

    • Main Results:

    • Organism exhibited differentiated endocrinal and hemodynamic patterns in response to distinct stimuli.
    • Responses varied significantly between psychological (color chart) and physical (cold pressure, ergometer) stressors.
    • Observed deviations from the homogeneous response predicted by the "alarm reaction" model.

    Conclusions:

    • The human stress response is characterized by differentiated physiological patterns, not a uniform "alarm reaction".
    • Specific endocrinal and hemodynamic parameters show distinct reactivity to different types of stressors.
    • Findings necessitate a revised understanding of physiological stress responses in clinical and research settings.
