| Outline of Final Research Achievements |
Previous studies revealed that the increase in outdoor temperature in summer is associated with higher mortality. However, we can not find a few evidence about the indoor temperature in summer. In the present study, we measured indoor temperature in spring, summer, and fall among 965 elderly participants. The higher indoor temperature of the bedroom was significantly associated with lower sleep quality and shorter sleep time.

| Academic Significance and Societal Importance of the Research Achievements |
外気温上昇時の死亡率上昇は重要な社会問題となっているが、一般住宅の居間や寝室の室温を、大規模な対象者で実測した結果は、夏の熱中症予防策の検討において重要な基礎資料となると考えられる。睡眠の質や量は、糖尿病やうつ病などの疾病発症との関連が指摘されている。今回の研究で認められた夜間の室温と睡眠の関連については、室温をうまく調整することによる疾病予防につながる可能性を示唆しており重要である。
