Description

Japanese people enjoy bathing, almost once a day. A large number of deaths while taking a bath at home are reported in Japan, and most of them are among the elderly and during the winter.<BR>We measured physiological and psychological responses during bathing and found large variations in blood pressure and pulse rate when getting into and out of the bath. In our study, 10 young men (19-25 yrs.) took a bath under immersion of 38°C or 40°C warm water for 10 minutes. They were instructed to get into and out of the bath, rapidly or slowly.<BR>When getting into the bath, the blood pressure rose and fell for a short time, and the pulse rate increased by less than 20 beat/min. The temperature of bath water and the speed of getting into the bath didn't affect these responses. When getting out of the bath after 10 min bathing, the blood pressure fell seriously and the pulse rate increased by more than 30 beat/min. The fall of the blood pressure was affected by the speed of getting out of the bath. When we compare taking a bath with 40°C warm water with 38 t water, the systolic blood pressure fell more seriously and the pulse rate increased less remarkably in the former. Since the pulse rate had already increased after taking a bath with 40°C warm water, we presumed that the pulse rate could not afford to increase for the behavior of getting out of the bath because of the subsequent serious systolic blood pressure drop.<BR>In sum, large temporal variations in blood pressure and pulse rate will occur getting into and out of the bath. The systolic blood pressure seems to fall seriously when getting out of the bath after 10-min bathing with 40°C warm water. Accordingly, getting into and out of the bath in a rapid manner will evoke a serious flux in the blood pressure and thus getting into and out of the bath in a much slower manner is recommended in order to avoid such profound fluctuations.
