* Decreased sweating

* Decreased urination

* Increased body temperature

* Extreme fatigue

* Muscle cramps

When these systems are disturbed due to loss of fluids there will be several common symptoms shared by most bodies, but there may also be unusual or unexpected responses depending on the particular person in question. Age also plays a part in the manifestation of symptoms. Signs of dehydration in a child will not be the same as those experienced by a teenager, adult or in the elderly. Dehydration prevention is the best treatment for every age group. heatstroke is always around the corner.
