Contra-lateral Thermal Effect of Used Hyperthermia in Body Part and Research on Body Composition / 日本温泉気候物理医学会雑誌

ABSTRACT

This research verified changes in composition in various parts of the body caused by conductive heat and the influence of the body composition on the effect of the contra-lateral thermal reaction in order to clarify factors for improving the effect of local bathing. The body composition was investigated by means of Segmental Bioelectrical Impedance Analysis. The percentage of fat was 14.23±2.40% in men and 29.60±7.66% in women, indicating a higher percentage in women than in men (p<0.01). The volume of body fluids in lower limbs was 6.46±0.83<i>l</i> in the right limb and 6.39±0.86<i>l</i> in the left limb of men, and 4.78±0.49<i>l</i> in the right limb and 4.78±0.49<i>l</i> in the left limb of women, indicating a higher value in men than in women (both p<0.01). During each bathing, the volume of body fluids on the surface, in deep part 1 and deep part 2 of men reached a maximum earlier than that of women.<br>Conclusions: 1) In bathing using external conductive heat, sebaceous is a large factor for changes in temperature both on the surface and in deep parts. 2) In bathing part of the body, there is little movement of total body water (TBW) and fluids inside the body eliminating risk factors of bathing such as the oligohidria, suggesting that bathing is a safe treatment for elderly people. 3) In the contra-lateral thermal reaction using conductive heat, the possibility of increasing the effect of raising the temperature on the surface and in deep parts on the non-bathing side was suggested.
