Boxplot representation and related Wilcoxon signed-rank test results for a TS, b SW, and c TC at baseline (BL) and at the time when thermal behavior was initiated (TB). \(^{1}\)TS subjective scale [18] (to the nearest 0.5 units; 1 = cold, 2 = cool, 3 = slightly cool, 4 = neutral, 5 = slightly warm, 6 = warm, 7 = hot). \(^{2}\)SW subjective scale [19] (to the nearest 0.5 units; 1 = very dry, 2 = dry, 3 = slightly dry, 4 = neutral, 5 = slightly wet, 6 = wet, 7 = very wet). \(^{3}\)TC subjective scale [18] (to the nearest 0.5 units; 1 = comfortable, 2 = slightly comfortable, 3 = uncomfortable, 4 = very uncomfortable). \(^{*}\)The median of differences is significantly different (p \(\le\) 0.048). The p-values for related Wilcoxon signed-rank test are noted (n = 8)
