A lot of drinks claims that electrolyte salts (like Na, Mg and K) keeps you hidrated, if you have diarrea or if you are a professional athlead.
And those salts are essencial in long fasts as well.
I don’t understand why
In: Biology
Your muscles and nervous system don’t function properly without adequate sodium, potassium, and chloride, and if you’re rapidly losing fluids through sweat or diarrhoea your supply of these is going to be depleted. Rehydrating with water alone is better than not rehydrating, but it can have the effect of diluting the remaing electrolytes in your body that are necessary to function (if sufficiently diluted, it can be fatal – see ‘water intoxication’). So, adding electrolytes means that muscle and nervous system function is supported as you rehydrate.
