Semantics are important when it comes to hydration to distinguish between two common terms associated with sweating: dehydration and hyponatremia. Differentiating terminology related to over and under consuming fluids and the concern for each is important. Consuming an insufficient amount of water that results in total body water weight loss is a condition called dehydration. Drinking too much water during exercise can cause water intoxification, (exercise associated hyponatremia (EAH)), a condition defined by dangerously low serum sodium levels.
