| Outline of Final Research Achievements |
In order to establish a new human thermophysiological model which can predict not only body temperature but also blood pressure and blood flow rate, we conducted reference data collections through some experiments and field surveys, and developments of the sub-models which compose our new model. In the experiments and field surveys, we obtained detailed physiological data under six steady-state and two unsteady-state conditions, and data on the daily life fluctuations of exposure temperature, blood pressure, etc. in winter. As the sub-model developments, we improved the thermal network and cardiovascular models, and verified their applicability. In addition, we developed a prototype of the physiological model to simulate the regulations of sweat, blood pressure and blood flow rate.

| Academic Significance and Societal Importance of the Research Achievements |
熱中症やヒートショックといった熱的健康被害のメカニズムには，体温だけでなく血圧と血流量が深く関わっているが，従来の体温調節系人体モデルでは血圧・血流量の予測が不可能もしくは不十分であった。本研究により，この問題の解決に近づいたことの意義は大きい。また，低温環境下における人間の体温調節能力の低さや，高温環境下における血流調節や血流経路の役割の重要性といった，従来型の人体モデルの改良にもつながる知見が得られたことの意義も大きい。
