Abstract
Many Japanese women have trouble with cold hands and feet. We reported how the skin temperature of the hands and feet are related to the environmental temperature in previous paper. As the outside temperature and the temperature in the bedroom increased from spring to summer, both the basal body and skin temperature of the hands and feet increased. However, the skin temperature of the hands and feet did not change with the basal body temperature, but were influenced more by the increase in bedroom temperature. The subjects were two otherwise healthy women aged 21 years, who complained of cold hands and feet. The dorsal and ventral skin temperatures of the hands and feet of a subject were measured using a thermotracer. Therefore, we compared subjects who woke up in a bedroom warmed to about 22-24℃ with those who woke in a bedroom at a normal winter temperature of about 9-17℃. During the low phase of body temperature, the basal body temperature and skin temperature of the hands of the subjects were significantly higher in the warmed bedroom. By contrast, during the high phase of body temperature, the skin temperature was relatively low, although the basal body temperature rose when we warmed the bedroom temperature. It was suggested that on warming the bedroom temperature of about 22℃ during high phase of body temperature in winter, skin temperature decreased because the basal body temperature was too high and her palm were sweating.
