Outline of Research at the Start

本研究では,熱中症発症を予防するために,発症前にアラームを発報できる熱中症アラームシステムを開発する.軽度の熱中症では,頻脈,大量発汗,めまい、立ちくらみ、気分が悪くなるなど自律神経系と関わりのある症状が見られる.そこで本研究では,自律神経活動を反映した生理現象である心拍変動(HRV)に着目して,ウェアラブル心拍センサを用いてユーザーのHRVを測定し,測定されたHRVデータをリアルタイム解析することで,近い将来に熱中症になる可能性を判定するアルゴリズムを開発する.熱中症発症前にアラームを発報できれば,ユーザーに休息や水分補給を促すことができるので,熱中症を回避できる.

Outline of Final Research Achievements

Preventing severe heat illness, called heatstroke, is crucial because it can lead to long-term multiple organ damage, including the brain, and results in more than 600 deaths per year in the United States. It has been reported that heat stress affects heart rate variability (HRV), which is the fluctuations of the R-R interval (RRI) on an electrocardiogram (ECG). We propose a method for detecting symptoms of heat illness based on HRV analysis in order to prevent exacerbation of heat illness. In the proposed method, monitoring abnormal changes in HRV caused by heat stress is monitored. To validate the proposed method, we recruited 103 healthy volunteers with risks of heat illness development. The result of applying the proposed method showed that a sensitivity of 75% (21 out of 28 cases) and a false-positive rate of 1.02 times per hour were achieved.

Academic Significance and Societal Importance of the Research Achievements

本研究提案した熱中症検知手法は、ウェアラブルセンサーでRRIデータを簡単に測定できるため、日常生活で活用できるものと考えられる.そのため,提案手法を活用することで,熱中症が悪化する前に適切な治療を受けられることに寄与し,人々の健康の増進と維持に貢献できる.
