Fig. 2

Finger skin temperature during baseline and CIVD at air temperatures of 20 °C and 25 °C. The minimum and maximum temperatures are shown as min and max, respectively (a). The time points from the onset of local cooling to the minimum and maximum temperatures are shown in (b). Data are presented as the average value ± SE. *p < 0.05 from 20 °C air temperature, and ^†p < 0.05 from baseline at the same air temperature, respectively
