Does drinking water reduce blood sodium?

What I can say is, for dehydrated patients (I'm an EMT), we usually give what's known as "normal saline," which is a 0.9% solution of sodium chloride in water.

However, to have any significant impact just drinking another glass or two generally does not cut it, if one maintains a high sodium diet.

You can actually take in so much free water that you drop your serum sodium level. In fact there is a condition called primary polydypsia (also called psychogenic polydypsia) in which this occurs.
What with the current war on salt, I was wondering if a simple way to reduce sodium would be to just drink lots of water. As I understand it, it will reduce your electrolytes of which sodium is one of the major ones. What with all the people who are dehydrated it might have other beneficial side-effects, rather than the more dubious side effects "normal" drugs have.
Serum sodium levels, however, are carefully regulated by your kidneys. It's very difficult to outpace a healthy set of kidneys (as John noted).
