    Summary
    This summary is machine-generated.

    Persistent stress leads to exhaustion and illness by disrupting homeostasis. A performance-arousal model explains how factors like psychosocial handicaps and stress management influence health outcomes, aiding in interventions for conditions like hypertension.

    Area of Science:

    • Physiology
    • Psychology
    • Health Sciences

    Background:

    • Persistent overloading leads to fatigue, exhaustion, and ill-health due to homeostasis violation and reduced resistance.
    • A breakdown is inevitable if the struggle against persistent stressors continues.

    Purpose of the Study:

    • To illustrate the course of persistent overloading using a shaped performance-arousal curve.
    • To clarify the effects of psychosocial handicaps, training, arousal reduction (relaxation), and rising arousal levels on health.
    • To provide a basis for screening and intervention in hypertension and coronary heart disease.

    Main Methods:

    • Utilizing a performance-arousal curve paradigm.
    • Incorporating principles of catastrophe theory.
    • Analyzing the self-defeating struggle in hypertension and coronary heart disease.

    Main Results:

    • The performance-arousal curve illustrates the progression from fatigue to exhaustion and ill-health.
    • Psychosocial handicaps are associated with lower performance curves, while training is associated with higher curves.
    • The model accommodates arousal changes from normal to destructive levels.

    Conclusions:

    • The performance-arousal paradigm offers a clear framework for understanding the impact of stress on health.
    • This model can guide screening and intervention strategies for stress-related conditions like hypertension and coronary heart disease.
