Forty Japanese college women were exposed to three thermal conditions (15℃, 25℃, & 40℃) in the Climatic Chamber of Kyushu Institute for Design Research to study relation of physique to the skin temperatures (auricle, chest, arm, thigh, leg & toe). High and statistically significant correlations are found among the skin temperatures at the ambient temperature of 25℃, while low and insignificant correlations are found among those at 15℃. The discrepancy in the correlationship between two thermally different conditions may suggest an alteration in the mechanism controlling skin blood flow in the cold environment. Twenty somatometric measurements including 4 skinflod thicknesses were also taken on the subjects. In this study a physique is assessed in terms of the first four principal components which have more than average eigenvalue and account approximately 72% of the total variance. A multivariate regression model was employed to analyze effects of physique upon the skin temperatures at each thermal condition. At 15℃ a null hypothesis that a set of multivariate regression coefficients equal zero was rejected at the 5% level of significance, although at the other thermal conditions the hypothesis was not rejceted. At the ambient temperature of 15℃ the regression coefficients on the first component were all positive. It is concluded that the more voluminous a women is, the warmer skin she has in the cold environment, since the first component represents rather "mass" factor than "size".
