Abstract
It is well established that altered body temperature (Tb) has an exponential effect on the oxygen consumption (\({\dot V}\)O2) of resting animals (Krogh, 1914). Alterations of Tb over a range larger than 20°C are routine for ectothermic vertebrates. The range of altered core Tb is smaller for homeotherms but is still significant in hyperthermia and hypothermia. In general, a l°C change in Tb causes an 11% change in metabolic rate (Q10 = 2.5). Consequently, fever or exercise-induced hyperthermia, will elevate oxygen demand and amplify the hypoxic stress of a mammal at high altitude or with cardiopulmonary disease. Conversely, hypothermia could be beneficial to any animal faced with a limited oxygen supply.
