Blood pressure, pulse rate (including ecg graphic observation) and skin temperature were determined in essential hypertension group, miscellaneous disease state group and normal control group who were exposed to the artifical climate room at 35°C or 5°C during 30' respectively. Hemodynamical analysis was made by our own modification of Wezler's method. 1) The blood pressure lowers in the hot environment and rises in the cold; this fluctuation is more remarkable in essential hypertension than in normal control. 2) There are some differences of reaction mode in juvenile, middle-aged and senile hypertension: while the change of diastolic pressure is most distinct in juvenile group, the fluctuation of systolic pressure is more dominant in the last two groups. 3) The response of skin temperature against generalized exposure to hot or cold environment in essential hypertension varies from that in normal control; there can be shown some possibilities of the existense of the generalized temperature dysregulation in hypertensive patients. The response of the skin temperature of extremity ends was more abnormal than that measured in fore-head and abdomen.
