Outline of Final Research Achievements

The purpose of this study is to investigate the diurnal variation of changes in regulatory system of circulation to head down tilt under humid heat exposure. In the evening, the response of increasing blood pressure was effective during supine position after head down tilt under humid heat exposure. It was indicated that higher activities of cutaneous vasoconstriction in the evening assisted to maintain of the central blood volume after postural change.
