How are electrolytes lost in sweat/why is salt?

  1. Feb 2, 2004 #1
    I understand that when you sweat, the water is to cool you and urea is excreted because it's a waste, however I don't know why salt is excreted, nor to I know how electrolytes are used in the process of sweating. Would someone care to enlighten me?

    probably because the water your are sweating is not pure. it is coming out of your body and it is picking up electrolytes as it comes out.
