研究領域	性差・月経周期・運動トレーニングが及ぼす影響に着目した女性の体温調節反応（発汗および皮膚血管拡張反応）の研究
研究紹介	熱い環境（暑熱環境）での運動時には，暑熱に対抗するための生理機能（発汗や皮膚血管拡張による熱放散）が優れていることが重要です．しかし，それらの機能には個人差が大きく，特に女性の特徴には不明な点が多く残されています．そこで，私の研究ではヒトを対象に，熱放散反応に欠かせない汗腺や皮膚血管のメカニズムを，非侵襲的な経皮薬剤送達法を用いて明らかにしようとしています．その中でも，女性の反応に焦点をあてて，男性との違い（性差），月経周期，運動トレーニングなどが及ぼす影響に着目して研究に取り組んでいます．
