Previously, we reported the effects of bathing on the elderly especially regarding cardiopulmonary functions. In this study, we compared hemodynamic changes induced by bathing between 12 apparently healthy elder volunteers (5 males, 70±5y) and 12 young volunteers (6 males, 23±3y). The subjects took 41℃-baths under 27℃ room temperature. We assessed the changes of the blood pressures (BP), heart rate, pressurerate products (PRP), oxygen saturations (Spo2), tympanic temperatures (Ttymp), and Holter ECGs. In the elder volunteers, the systolic BP did not show significant changes during bathing but decreased after bathing more than the control value. The young volunteers showed a decrease in SBP even during bathing. Diastolic BP began to decrease during bathing and continued after bathing in both the elder and young volunteers. In the elderly PRP increased during bathing and decreased after bathing, but in the youth it increased just after bathing and decreased after bathing. Spo2 decreased gradually after bathing in the elderly. Hemodynamic indices changed more in the elderly than in the youth.
