Consistent, excessive body heat can be attributed to several factors. The most notable factors include body metabolism, convection, conduction and radiation, according to the Chicago Tribune.
How frequently a person exercises has a direct effect on her metabolism in general and in effect, her core temperature, according to the Chicago Tribune. Someone who exercises daily typically has a higher body temperature than someone who does not. The Tribune also reports that if someone is prone to being outdoors within proximity to pavement, they typically carry a higher core temperature. This process is known as conduction and is typical among city dwellers.
Convection and radiation may also be culprits, as reported by the Chicago Tribune. Living in a region where someone is exposed to sunlight (radiation) for a majority of the day as well as warm breezes (convection) ultimately yields a higher core temperature even when that person is out of the elements.
Another cause is known as evaporation. The body's natural cooling system is less efficient in humid conditions. This inhibits sweat glands and ultimately leads to a higher body temperature in people who live in humid regions, according to the Chicago Tribune. It is common that people experiencing evaporation effects develop goosebumps as a result of their circulatory system's failure to dissipate heat from humidity.
