Final answer:
Excessive heat and dehydration with a temperature of 101-102F can lead to heat exhaustion or heat stroke due to inadequate cooling and hydration. The fever itself can result from infection-induced changes to the body's temperature set-point, exacerbating dehydration.
Step-by-step explanation:
The result of excessive heat and dehydration with a temperature of 101-102F can vary, but if the temperature is a result of environmental factors and not an internal infection, the most likely outcomes are heat exhaustion or heat stroke. These conditions occur due to inadequate cooling mechanisms in the body coupled with dehydration. The body normally cools itself through sweating, where evaporating sweat removes thermal energy from the body. However, without adequate water intake, sweat production decreases, and body temperature may rise dangerously high, especially in a humid environment where evaporation is less effective. A fever by itself, such as might be caused by a viral or bacterial infection, is an upward adjustment of the body's temperature set-point and can lead to dehydration if fluid intake doesn't increase accordingly.
