Change of tympanic temperature during lower leg water immersion. Data are shown as average values in every 10 min. The change of temperature was calculated as increase of temperature compared with time of intake of beverages. Thus, in 0- to 30-min period, temperature was compared with point of “0” in figure; in 30–60 min, temperature was compared with point of “30” in Fig. 1; in 60–90 min, temperature was compared with point of “60” in Fig. 1. Arrows indicate the timing of beverage intake. Values are mean ± SD. *p < 0.05 compared with mineral water
