Fig. 3From: Body cooling effects of immersion of the forearms in high-concentration artificial carbonic acid water at 25°CTime-course of ear canal temperature during the experiment (a). Changes in ear canal temperature from before immersion (b). Changes in ear canal temperature before and after immersion (c). All values are expressed as mean ± standard deviation. *P < 0.05 between tap water and CO2 waterBack to article page
