Re: --answer-- tap water-low blood pressure

then you would want to look at magnesium which also plays a big part in regulating b/p. If you research info on magnesium you will find a deficiency in it can cause low or high b/p and givng your body waht it needs to adjust so it will run better. Sodium cannot cause low b/p. There is something else going on but it is not sodium, by its very nature and what it does in the body it cannot cause low b/p. Might want to check out
