Change in rectal temperature. Changes in rectal temperature (ΔTre; mean ± standard error) in summer D (●; n = 7), summer non-D (○; n = 8), winter D (■; n = 7), and winter non-D (□; n = 8) groups. In a post hoc test, rectal temperatures were significantly lower from 40 minutes after the start of cold exposure only in the summer non-D group ( P < 0.05)
