| Outline of Final Research Achievements |
Coldness of the body is one of the unidentified complaints frequently observed in females. The brain activities in adults with a cold constitution were characterized by specific patterns, that is, a lower appearance of low-frequency α waves and a higher appearance of β waves. Independently of the changes in these brain activities, the increases of core and skin temperatures induced by skeletal muscle exercise occur an increase of thermal comfort and a decrease of cold feeling in the distal portions of the extremities. Light exercise interventions for 1-3 months mitigated coldness in a whole-body and the distal portions of the extremities. The mitigation was due to a reduction in cold sensitivity and an enhancement in the skin vasodilator function of the distal portions of the extremities.

| Academic Significance and Societal Importance of the Research Achievements |
日本文化における冷え症は疾患には起因しないが強い冷感によって日常生活に困難を伴う不定愁訴としてとらえられてきた。諸外国で冷え症そのものを扱った研究は少ないが、本邦においては冷えと食事や生活習慣との関連、月経や妊娠との関連、冷え症の客観的評価などの研究がみられる。冷え症の生理学的特性については温度感覚や皮膚温から研究したものが散見されるが、脳機能や皮膚循環機能については不明な点が多く残されている。これらの機能的特性を明らかにした上で、冷え症の緩和策としての身体運動の効果とその機序を解明することは、冷えで悩む人々の生命と生活の質の向上につながるものであると考える。
