Health The human body consists largely of water -- muscle tissue, for example, is a surprising 75%. In the course of a normal day, we lose some of this water, and, like a car with a leaky radiator, if we don't constantly replace what we lose, we can go from well-oiled machine to wheezing wreck. Everyone has seen television footage of marathon runners stumbling towards the finish line, their disorientation and spastic-like movements clearly indicating an extreme state of dehydration. These graphic images highlight the crucial role that water plays in virtually every bodily process, and the problems that can occur when it is deficient.

It's very easy, especially in summer, to spend too long playing or working in the sun and forget to replace the moisture lost through even relatively mild exertions. That throbbing headache is the body's friendly reminder to, "Drink more water next time, dummy!" Many health practitioners believe that a large proportion of the North American population suffers chronically from mild dehydration.
