Application of a Heat- and Steam-Generating Sheet Increases Peripheral Blood Flow and Induces Parasympathetic Predominance

Serial changes of the tissue temperature during and after application of the HSG sheet. ° (anterior abdominal region) or ∆ (lumbar region); control group (sham belt), ●; HSG sheet applied and fixed as a waist belt to the anterior abdominal region, ▴; HSG sheet applied and fixed as a waist belt to the lumbar region, abdominal region (a); skin temperature beneath the HSG sheet, abdominal region (b); subcutaneous tissue temperature, lumbar region (c); skin temperature beneath the HSG sheet, lumbar region (d); subcutaneous tissue temperature, periphery (e); fingertip skin temperature, periphery (f); instep skin temperature. The difference between the tissue temperature at rest (=0°C) and the tissue temperature during the 60-minute period of application of the sham belt or HSG sheet belt to the anterior abdominal region or lumbar region (the period marked with dotted line) and the 30-minute period after removal of the sham belt or HSG sheet belt (until 90 minutes during and after application of the belt/sheet) are shown. Data are mean ± SE of the 10 subjects. *() and **() indicate significant differences from the control group (Tukey-Kramer’s multiple comparison).
