Camels require very little water because they are able to tolerate relatively large changes in their body temperature. while humans keep their body temperatures constant to within one or two celsius degrees, a dehydrated camel permits its body temperature to drop to 34.0∘c overnight and rise to 40.0∘c during the day. (note: the specific heat of a camel or other mammal is about the same as that of a typical human, 3480 j/(kg⋅k). the heat of vaporization of water at 34∘c is 2.42 × 106 j/kg
