The reason why over hydrating can be dangerous is that when we consume large amounts of water when exercising, blood plasma (the liquid part of blood) increases, while the sodium concentration in the body fluids decreases, both as a result of the dilution by the water but also because sodium is lost by sweating.
Hyponatremia, or low blood sodium, generally happens after drinking too much plain water and can lead to adverse effects and tissue damage, and interfere with brain, heart, and muscle function.
