Fig. 3. Temperature differential between surface Ts and ambient
temperature Ta (
Tsa) as
a function of Ta for eyes (filled circles), nose (filled
squares), ears (filled triangles), feet (filled diamonds) and flank (open
circles) in normoxia (A) and after 15 min of hypoxia (B). A linear
relationship between
Tsa and
Ta implies minimal specific thermoregulatory adjustments
in Ts, whereas a departure from linearity at a given
Ta implies thermoregulatory adjustments at that surface to
either increase or decrease heat loss.
