Research Abstract

Hyperthermic conditions lead orthostatic intorelance. The purpose of this study is to investigate the diurnal variation of changes in regulatory system of circulation during thermal stresses with transient decreases in blood pressure and evaluate the effect of whole body skin cooling and moderate exercise to maintain orthostatic torelance. The regulation of cerebral blood flow to transient decreases in blood pressure only improved in the evening under mild hyperthermic condition. It was shown that the diurnal variations of improvement of circulation system by skin cooling and exercise.
