When you become dehydrated, your body has to work harder to retain water. Fever is a symptom only generally seen in children. Body temperature rises due to excessive sweating and inability to replensh with water. Sweating is the body’s natural air conditioning system. When we get hot, vasodilation occurs to stimulate heat conduction from our bodies to the environment (viens essentially enlarge- which is why the skin looks red). The body responds to vasodilation and heat conduction by stimulating sweat glands. In a dehydrated person, water is less easy to come by, so the body’s natural cooling system does not work as well (there is no sweat to evaporate from the skin to cool the surface of your body). Therefore, temperature rises more easily.
Check out this physician report on SYLLABUS. And if that link doesn’t work, go into Yahoo search and put in Pathophysiologic relationship of fever and dehydration. This article is a wealth of information. I clicked on Objecives (PDF) when all the results came up. So, the information is out there for you.
Hope this was helpful.
