In the scorching heat of the desert, a lifeless object, such as a rock, can reach a temperature of over 50 degrees Celsius. A camel in this environment, like a man, maintains a tolerable body temperature.But where the human temperature remains almost constant as the day warms up, the camel's temperature rises slowly to about 105 degrees. When the temperature of the camel increases, the animal sweats very little; It is only when the temperature reaches 105 degrees that it sweats freely. The high temperature of the camel also reduces its heat absorption, which of course is due to the difference between body temperature and room temperature.
The camel further reduces the heat load on the body, which means that the temperature can drop below normal during the cold desert. At dawn, the temperature may have dropped to 93 degrees. Therefore, most of the day will pass before the animal's body heats up to 105 degrees and must sweat. Due to its flexible body temperature, camels sweat a little except during the hottest hours of the day, when a man in the same environment sweats almost from sunrise to sunset. . . .
The camel uses comb hair insulation to further reduce the heat load. Even in summer, when the camel loses most of its wool, it has a layer that is several inches thick on its back where the sun goes down.If we sheared the wool from one of the camels, we found that the hairless animal produce 60% more sweat than a skinless animal!
The camel's hump also indirectly contributes to reducing the animal's heat load. Almost all mammals have a food supply in the form of fat, but in most of them the fat is distributed fairly evenly throughout the body. under the skin. By concentrating the fat in a position, the camel lacks insulation between the body and the skin, where evaporation cooling takes place. The absence of insulation facilitates the circulation of heat, just as wool insulation slows down the heat flow.
