Outline of Final Research Achievements

Hyperthermic conditions lead othrostatic intorelance. The purpose of this study is to investigate the diurnal variation of changes in regulatory system of circulation during thermal stresses (whole body skin warming and cooling) with transient elevation in blood pressure. The response of decreasing heart rate to transient elevation in blood pressure was effective during whole body skin warming in the morning. In contrast, that response during whole body skin cooling was impaired in the morning. It might not be sufficient to deal with transient elevation in blood pressure under cooled conditions in the morning.
