居住環境の改善がもたらす健康維持増進に着目し, 大規模実測調査を行った。断面調査では, 住宅内環境や断熱性能と健康(血圧・活動量・睡眠)の関係を調査し, 低室温環境が血圧の上昇を招くこと, 断熱性能の向上による非居室の温熱環境改善が活動量向上に寄与することを示した。中でも, 高断熱住宅への転居前後の調査では, 転居後の室温上昇につき睡眠効率が向上することが示された。また, 高齢者を対象とした調査では, 住宅を寒いと感じる頻度が少ない者ほど健康寿命が長いことが示唆された。以上を踏まえた要因分析では, 高断熱住宅の普及増加が脳血管疾患入院患者割合を抑制する可能性が示され, 高断熱住宅普及の重要性が示された。
Focusing on health promotion which improvement of living environment brings, large scale measurement survey was conducted. In the cross-section survey, we investigated the relationship between housing environment and insulation performance and health (blood pressure, activity, sleep), and low-temperature environment leads to an increase in blood pressure, improvement of thermal environment of non-living room contributes to improvement of the physical activity.Among them, survey before and after moving to a highly insulated household showed that improvement of sleep efficiency after moving. In addition, in the survey targeting elderly, it was suggested that the person who rarely feels cold in their house has a longer healthy life expectancy. Based on the above factor analysis, possibility that spread of high insulated houses will suppress the proportion of inpatients in cerebrovascular disease in hospital was shown, and the importance of disseminating highly insulated housing was shown.
