Fig. 5. Normalized mean heat fluxes of five body locations per 5-min time interval [HW − 15 to HW + 15, HW + (25–30)]. Heat fluxes were normalized with baseline data to provide a percent value. Using repeated-measurement analysis of variance for nonparametric data (Friedman test with Dunn posttest), heat fluxes were significantly different versus  baseline at HW + (0–5) (abdomen, forearm:P < 0.05), HW + (5–10) (cheek:P < 0.05; abdomen, forearm:P < 0.01), HW + (10–15) (cheek:P < 0.05; abdomen, forearm:P < 0.01). The last data point [HW + (25–30)] could not be included in the statistical data analysis because several subjects completed the study before (incomplete matrix).
