Linear regression line between mean skin temperature (mean T _sk) and thermal sensation for the whole body (a: left follicular phase, right luteal phase, n = 8), and mean T _sk and thermal pleasantness for the whole body (b: left follicular phase, right luteal phase, n = 8) at 0–120 min. The gray lines represent the linear regressions for each subject. The bold black lines and equations were based on average slope and intercept of the regression lines, which were estimated from results for all the subjects. Correlation coefficients (R) and probability values (P) are the maximum and minimum values for all the subjects
