PROBLEM TO BE SOLVED: To provide a method for increasing a blood flow, which improves symptoms such as mental stress by increasing the blood flow.SOLUTION: On specific sites of the body such as at least two sites on the soles of right and left feet having sites intersecting with inner malleoli on an extension of an inside border between first and second toes, a blood flow is measured before the application of heat stimulation a rate of increase in the blood flow before to after the application of the stimulus to the specific sites is calculated and the heat stimulation is applied so that the rate of increase in the blood flow before to after the application of the stimulus can be 30% or more.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】血流量を増加させ、精神的ストレス等の症状を改善するための血流量を増加させる方法を提供する。【解決手段】身体の特定部位として、例えば、第1と第2指間で内側辺縁の延長線上で内踝の垂線と交差する部位を備える左右の足裏の少なくとも2ヶ所に、熱刺激を与える前の血流量を測定し、特定部位に刺激を与える前後の血流量の増加率を求め、刺激付与前後での血流量の増加率が、30%以上になるように熱刺激を付与する構成とする。【選択図】図1
