Twenty-eight healthy female subjects aged 61 to 88 years old wearing only shorts and brassieres lay in a supine position on a bed and their cold/warm thresholds were measured over 26 body regions under the conditions of 28°C ambient temperature and 50% R.H. Ten female subjects aged 20 to 25 years old were also measured under the same conditions as the control. The cold/warm thresholds of the leg, foot and sole were high and those of the forehead, cheek and chin were low for each group. Both thresholds were higher for the elderly than they were for the young women, and they increased with age. In addition, principal component analysis of the cold/warm thresholds revealed that individual differences in regional contrast between the front-back/trunk-peripheral of the cold/warm threshold were greater among the elderly than they were among the young women and they increased with age.
