The purpose of this study was to investigate physiological and subjective responses during and after bathing in three different bathing methods. Eight healthy males bathed for 10 minutes, and then rested for 30 minutes. Three kinds of bathing methods - standing shower, sitting shower and sink bath - were adopted in this experiment. Water temperature and flow volume of the showers were kept at 41 degrees C and 11 liter/min, while water temperature of the bath was kept at 40 degrees C. Rectal temperature, skin temperatures and heart rate of the subjects were measured continuously during bathing and the subsequent 30-minute rest. Blood pressure and votes for thermal sensations were recorded before bathing, after 5 and 10 minutes of bathing, and 5, 10, 20 and 30 minutes after bathing. The following results were obtained. 1) Although rectal temperature rose, on the average, by 0.15 degrees C in all bathing methods, there were no significant differences among the three bathing methods at any time in the experiment. 2) Mean skin temperature (Tsk) during the sink bath was significantly higher than that in the standing or sitting shower. After bathing, Tsk of sink bath was slightly higher than those of the remaining conditions, but did not significantly differ among the bathing methods. 3) Heart rate increased gradually during all the bathing methods, however, only HR in the standing shower exceeded 100 beats/min which was significantly higher than those of the two remaining bathing methods. 4) Blood pressure (BP) decreased rapidly during the sink bath in contrast to an increased BP in the sitting and standing showers.
本研究的目的是调查三种不同沐浴方式过程中和沐浴后的生理及主观反应。八名健康男性进行了10分钟的沐浴，然后休息30分钟。本实验采用了三种沐浴方式——站立淋浴、坐式淋浴和盆浴。淋浴的水温及流量保持在41摄氏度和每分钟11升，而盆浴的水温保持在40摄氏度。在沐浴过程及随后30分钟的休息期间，持续测量受试者的直肠温度、皮肤温度和心率。在沐浴前、沐浴5分钟和10分钟后以及沐浴后5、10、20和30分钟记录血压及热感觉投票。获得了以下结果。1）尽管在所有沐浴方式中直肠温度平均升高了0.15摄氏度，但在实验中的任何时间，三种沐浴方式之间均无显著差异。2）盆浴期间的平均皮肤温度（Tsk）显著高于站立或坐式淋浴时的平均皮肤温度。沐浴后，盆浴的Tsk略高于其他情况，但在不同沐浴方式之间无显著差异。3）在所有沐浴方式中，心率均逐渐增加，然而，只有站立淋浴时的心率超过100次/分钟，显著高于其他两种沐浴方式的心率。4）与坐式和站立淋浴时血压升高相反，盆浴期间血压迅速下降。
