Abstract:
The purpose of this study was to clarify difference in heating effect of the two types of bathing for the elderly, footbathing at 44°C and full bathing at 40°C.
The subjects of this study were nine elderly persons for footbathing (average 73.5 years old) and 10 elderly persons for full bathing (average 77.4 years old). The tympanic temperature was measured using a thermistor, sweat rate using the ventral capsule method, and blood pressure and heart rate using an autonomic spygmomanometer during control period 10 minutes before bathing, for 20 minutes during bathing, and for 10 minutes after bathing. Subjects wore plain clothes while taking a footbath time or swimming trunks while taking a full bathing. The ambient temperature was set to 20°C during the footbath or 26°C during the full bathing.
During the footbath, the tympanic temperature increased to 60% that of full bathing and a significant increase of sweat rate was observed. In contrast, during full bathing, a significant rise in systolic blood pressure was observed immediately after bathing started due to hydrostatic pressure and a significant drop of diastolic pressure was observed after bathing due to heating during bathing.
These findings suggest that the footbath is safe, does not cause any change in blood pressure and is expected to provide mild warming for the elderly.
