Fig. 3

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