I'd like you to qualify this. "Not remotely accurate." Do you suggest sea water is a remedy for dehydration. Or are you suggesting osmosis doesn't occur across cell membranes. Or maybe you're disputing the process of osmosis altogether and the transfer between varying salinities. Which one is it exactly?
The article is talking about the dangers of drinking sea water when severely dehydrated if stranded on the coast or at sea. You can't extrapolate the sodium in Gatorade to drinking straight sea water. That's not only haphazard, but completely irresponsible considering we're discussing health and survival.
Also, the images depict cells all over the body; not just in the small intestine and certainly not villi.
Sure, this isn't the most robust explanation of a bodily function. This is an expedition travel website. It's not the Journal of Medical Science. The purpose of the article is to stop people drinking sea water as a remedy for dehydration. As some people have mentioned, small controlled quantities may help. But when you're that delirious, I can't help but think even having that thought in your mind would cause more harm than good.
- jforman 15y agoYes, I read the article. "Do you suggest sea water is a remedy for dehydration. Or are you suggesting osmosis doesn't occur across cell membranes. Or maybe you're disputing the process of osmosis altogether and the transfer between varying salinities. Which one is it exactly?" I just mean this: whether seawater causes dehydration in small quantities is a complex question, one which reading this article will provide absolutely no insight into. "You can't extrapolate the sodium in Gatorade to drinking straight sea water. That's not only haphazard, but completely irresponsible considering we're discussing health and survival." I never said that seawater is hydrating? Seawater lacks glucose and may have too high a salt concentration to promote hydration even if it did contain glucose. My apologies to anybody who misinterpreted my post after finding themselves stranded on a desert island. "Also, the images depict cells all over the body; not just in the small intestine and certainly not villi." The images are clearly presented in such a way as to suggest that simple osmosis between cells and seawater-containing blood is the operative factor in determining hydration. This is totally untrue. "Sure, this isn't the most robust explanation of a bodily function. This is an expedition travel website. It's not the Journal of Medical Science." That doesn't give them license to just make stuff up.
