It is possible to over hydrate, and over hydrating happens in extended timeframes when you're drinking just water without any electrolytes in it. So, if you're doing an exercise program for an extended amount of time, make sure that you are rehydrating with a fluid that includes sodium and potassium. Don't drink plain water if you're running a marathon.
