yes, I expected that... that is what they say.... they also say coffee will

dehydrate you too, but I drink my pot of coffee in the morning, run 5 miles

in the Mississippi sun, then come back and guess what I do before I drink a

drop of water (maybe it's the beer)?

Yes hyponatremia is pretty rare (one girl died at Boston marathon last

year), but I am still concerned about people who might tend toward dietary

extremes to blindly drink 10 extra glasses of water while probably also

cutting salt from their diet.

I concur that our (even my) thirst response is slow to respond. I ran in a

marathon a few years back where I didn't drink enough in the early stages,

and when I finally did " feel " the thirst it was difficult to make up for it.

I cannot tell " you " precisely what " you " need to drink, but perhaps " you "

can figure it out with a little common sense... general advice should be

taken with a grain of salt.... :-).

PS: I just saw a scary factoid on a website that said adults are 70% water

while elderly are only 50%.... I guess those elderly don't drink their 10

glasses a day.

PPS: don't believe everything you read on the internet especially this....

My husband is a runner too. Sorry, beer doesn't count. Alcohol is a

dehydrator, and a lot of hangover symptoms are actually due to

dehydration.

Some of the posts recently seem to come from a book

Your Body's Many Cries for Water

by Fereydoon Batmanghelidj

See his website at http://www.watercure.com/

I suspect a great deal of it is valid, but some of the claims are

pretty far out there.

Dehydration is implicated in some heart attacks - reduced blood

volume makes everything in the blood stickier. I believe this was

part of the issue with the news correspondent that died in Iraq of a

heart attack.

I was waiting for someone to bring up hyponatremia. This is actually

very rare and you really have to work at getting too much water.

There are guidelines for how much water to drink when exercising

vigorously in hot weather. See

http://www.spinalhealth.net/hyponatremia.html near the bottom of the

page. Also try http://www.runnersworld.com/ and put hyponatremia in

the search window. For vigorous exercise lasting longer than 60-90

minutes in hot weather, use sports drinks.

The color of your urine is a good indicator regarding your overall

hydration state in general, but it is not immediate enough to help

while exercising. Also, if you're really dehydrated, you won't be

urinating.

There's nothing wrong with a lot of things perhaps - doesn't it make it part of a nutrition regimen. I prefer to eat things for which there is scientific backing. Sodium is one of those things that is assumed to be ok.

Rather I'd like to see a justification for putting it in foods other than taste. Users can easily add salt. For some foods like greens, sodium is needed in canning, also for preservation of bread. We could explore other choices. There are peoples in the world who don't have a "craving" for salt and ingest very little sodium, so I think it's learned.

Folks are considered not "salt sensitive" if they're BP doesn't rise significantly more than others. But even a small rise in non-hypertensives is indicative of something happening. And I think an unnecessarily elevated level may be related to lifespan. There is more research coming.

Regards.

About salt--why do we crave it? Why we enjoy sugar is quite obviousfrom an evolutionary perspective, but why the salt? A long time ago Isaw a documentary on the benefits of salt and why we started cravingit but I can't remember any of it. From the little research I've seen,there isn't really any reason to worry about extra salt unless you'resalt sensitive. Interesting question, though. -Zulu
