Figure 1 Rectal temperature (mean±SD) (triangles), body temperature (circles), and skin temperature (squares) in response to ambient gradual cooling (A) and rewarming (B) in normoxic (filled) and hypoxic (open) conditions. * P<0.05 difference between hypoxic and normoxic conditions.

Figure 2 CVC (mean) response of the great toe and little toe to gradual whole body cooling and rewarming. A and B, great toe cooling and rewarming, respectively. C and D, little toe cooling and rewarming, respectively (n=12). Normoxia, 20.9% O2 (black circles), hypoxia, 11.5% O2 (open circles). CVC, cutaneous vascular conductance.

Figure 3 CVC (mean) response of the thumb and little finger to gradual whole body cooling and rewarming. A and B, thumb cooling and rewarming, respectively. C and D, little finger cooling and rewarming, respectively (n=14). Normoxia, 20.9% O2 (black circles), hypoxia 11.5% O2 (open circles). *P<0.05 for normoxia vs hypoxia. CVC, cutaneous vascular conductance. Wilderness & Environmental Medicine 2018 29, 45-55DOI: (10.1016/j.wem.2017.11.006) Copyright © 2017 Wilderness Medical Society Terms and Conditions

Figure 4 Thermal comfort (mean±SD) against mean skin temperature during (A) cooling and (B) rewarming (n=14). Normoxia, 20.9% O2 (black circles), hypoxia 11.5% O2 (open circles). *P<0.05 main effect of condition.
