Crocodilians have a "preferred" body temperature of around C, and to achieve such temperatures they move back and forth between warm and cool parts of their environment. In cold weather they bask in the sun to heat up, and in hot weather they seek shaded, cool areas to avoid overheating. Basking crocodilians will usually orient themselves so that the maximum body surface is exposed to the sun.
However, as they warm, they often face the sun, thereby reducing heat uptake by the relatively small head, whilst the body continues to heat up. When oriented in this way crocodilians will often open their mouths, allowing the brain to cool through evaporative cooling, while the rest of the body is heating.

With a decrease in body temperature, all metabolic processes begin to slow. Hypothermia can be life-threatening. Hyperthermia describes a body temperature that is higher than normal.
One example of hyperthermia is fever. A fever is generally considered to be a body temperature over 38 degrees Celsius A fever is the body's natural defense to an infection by a bacterium or virus. Fevers are one of the body's mechanisms for eliminating an invading organism.
It is only taught at Exillium , even though some elves feel that they need to learn it even if they weren't banished; for example, Kesler taught Dex.

An endotherm is an animal that regulates its own body temperature, typically by keeping it at a constant level.

Fevers may even make the immune system work more effectively. Heat exhaustion and heatstroke are other examples of hyperthermia. These occur when heat production exceeds the evaporative capabilities of the environment.
Heatstroke may be fatal if untreated. Marieb, Elaine.

Thermoregulation, by definition, is a mechanism by which mammals maintain body temperature by tightly controlled self-regulation, no matter. A healthy body functions best at an internal temperature of about 37°C (°F). But everyone has their own individual "normal" body.
