In order to function properly, the human body needs water and ample supplies of it. Contrary to the popular belief that water is needed during a marathon or long run. More and more research is showing that dehydration does not merit the concern we have been mislead to believe.

On the contrary, health experts theorize that too much water can be a bad thing and there is an appropriate way to remain hydrated.

During exercise, the body loses we water primarily through sweating. While the body is comprised of water, there is not any significant scientific evidence supporting the concept that dehydration is a detriment for all runners. Dehydration can be triggered by being lost in a desert for an extended period of time staying out in a desert for a long period of time. Running a race and exercising are not the prerequisites for dehydration.

Dehydration means the body is limited in water and fluids. Not to mention, while the body does emit enough fluids during a run, most people do not run long enough for dehydration to be a detriment. Alternatively, there is a growing number of the absolute opposite of dehydration, hyponatremia. Hyponatremia transpires when the serum salt level is lower than a specific number in the blood.

The indications of hyponatremia happen with when the salt level plummets. The first side events include dizziness and faintness. Certain people experience vomiting, diarrhea and nausea. More advance stages of the hypoantremia entail seizures where the brain swells and pulmonary edema. If the symptoms are left untreated, the brain stem will herniate and potentially expire if serum sodium drops too low.

So, the next time you consider over-indulging in water before running, remember too much of a good thing is not good either.
