Data are means ± SD (WA = water, MU = mustard, GI = ginger, Diff = mean difference of AN minus HC, CI = confidence interval, and ES = Cohen’s d effect size). aTotal score between 0 = cold and 8 = hot; btotal score between 0 = cold and 4 = hot. Bold indicates confidence intervals that do not contain zero.
