He also set out the clinical implications of the general adaptation syndrome: In his discussions of adaptation energy and exhaustion he tended to cite the result of his own experiments rather than refer to any broader literature to support his arguments.

The upper character represents: Physiological changes can include changes in sympathetic activation or HPA activity, and immunological function. Studies have also shown that psychological stress may directly contribute to the disproportionately high rates of coronary heart disease morbidity and mortality and its etiologic risk factors.

For other contemporary studies of combat stress, see Stafford-Clark David. Selye discovered and documented that stress differs from other physical responses in that stress is stressful whether one receives good or bad news, whether the impulse is positive or negative.

Under other circumstances the activity may differ. Other regions of the hypothalamus both directly and indirectly inhibit HPA axis activity. A Year in the Political Life of a Drug. This chapter has attempted to extend the process of historical reconstruction.
