The most "ingenious" way to hydrate yourself!

We would tell people in the Army that if we couldn't get this IV in we would stick the tube up your ass and step on the bag. Luckily we always hit a vein.

That is what I was taught in a combat medic class. Also for severe burn victims.
 
I've tried digging behind the dunes..went like 5 feet and didn't get squat.

Nope, you're not alone.
Hey -jaymeister99, it depends where you are. I'm up North so I could resort to some tree saps, birch maple or alder for example. You could collect dew with cloth, find rain water in the crooks of trees, bury cloth in moist ground and wring it out...
As for solar stills consider the fact that you need clear plastic, I know what They say but I don't think They applied the theory; a green poncho really doesn't work well at all, and if the humidity is too low you better have a real big piece of plastic. It works good if you have a slope on a hill that has a lot of grass or wet ground though.
So what kind of environment will you face?

Nothing new really ... Bear Grylls already demonstrated this.

IMO, we should all be thanking Bear for showing the utility of vaseline coated cotton balls for more than starting fires. :D

It may be my thing, but I always thought the southern port is an exit, not an entry.

It works! I just tried it out in the bathroom and it made a big mess, but I feel great! I used coffee! Afterward some walmart employees came in the bathroom as I was washing up and were freaking out when they found the mess. I told them it must have been someone else. :D

Haha, this alone may have made my day. Of course in my visualization there are black bars blocking out a majority of the picture.

That was his penis......

:D

Edit - I'd like to check on this in the physiology literature. The water absorbance capacity of the colon and large intestine is well known. That is its main function, to recover water from the bowels before moving it on out. However, I'm dubious about the salt water part. I cannot see how this would not contribute to excess salt entering the body. We excrete salt through the kidneys and thus the intestines aren't likely to be equipped for barring salt from entering our bodies. If it were, then water would flow out of our bodies into the intestines [full of seawater] to reachieve osmotic balance.

I don't think the sea water would be in the body long enough for osmosis to be an issue (that's the other thing about an enema)and the salt content needs to be a lot higher before excess salt becomes a problem. If you're still in a survival situation at sea when hardening of the arteries starts to become a problem, we'll have to call you Robinson Crusoe.
 
Ah I see. he's got a multi use tool, must be all that Special Forces Training, and I bet the little woman has a sharp tongue.:D:D:D

I disagree - speaking as a biologist here, and now having done a small bit of reading on the subject matter.

Basically, the human colon is designed to effectively removed both water and salts from the lumen contents. In fact a primary function of the colon is to recollect/recover the large amount of water (up to 9L/kg) added by the body to facilitate digestion in the upper portion of the digestion tract. There still appears to be debate regarding that physiological mechanism by which the colon is able to effectively dehydrate feces against an osmotic gradient relative to body fluids. The mechanism of water absorption differs relative to the small intestine which essentially allows water to flow freely across enterocyte membranes via aquaporin channels, but water here flows in whichever direction (from lumen to cells or vice versa) the osmotic gradient favors. However, in the colon, as the fecal material gets further dried out it achieves a higher osmolarity relative to the body fluids and this would tend to direct water from the body back to the feces. Here it is believed that the epithelial cells of the colon possess special properties and are able to generate micro-osmolar gradients within crypts formed by collections of enterocytes that facilitate net flow of water from feces to the body. This is believed to occur through a process wheresalt is actively pumped into these specialized crypts forming a hypersaline solution (relative to feces) which then permits further fecal dehydration. Interesting enough, the creation of this hypersaline solution involves active transport of sodium and chlorine ions from the lumen side into the crypts by exchange with potassium, hydrogen ions and bicarbonate ions.

What this means is that in order to realize a high efficiency of water absorption by the colon, the colon must also realize (and expend energy doing so) a high efficiency of salt absorption. By introducing salt water into the colon, the colon must compensate for the decrease in osmolar gradient by further absorption of salts. In the end, you get the same thing happening as occurs when you drink salt (ocean) water. Your body absorbs too much salt per unit of water - your blood becomes too salty and this essentially sucks out water from your cells wreaking havoc with homeostasis. Your kidneys compensate by cranking up its rate of salt excretion. However, your kidneys are not capable of clearing salt at concentrations approaching that of salt water if too much seawater is consumed. In fact your kidneys will start to excrete water in its effort to excrete salt such that you will lose more body water than what you have taken in by drinking seawater. This is why sea water dehydrates you rather than re-hydrates you. The same process should also happen by engaging in a salt water enema.

Where I have read independently the use of enema under drift at sea conditions is when you have fouled, but non-salty water. For example, contaminated rain water that is in your raft that has come into contact with feces or blood ect that should you drink it will make you vomit. Performing an enema with this nasty water would enable you to circumvent the vomiting act. Sure, you might just squirt that stuff back out, but by vomiting you would be evacuating precious water contained in your stomach and you would rather hold onto that. I admit, I did not watch either Bear or Mike shoving a tube where the sun doesn't shine. It strikes me that doing so with salt water won't help things. Do so with fresh water (or at least less salty than seawater) that could not be purified independently might be useful.
 
Thanks for clearing up that salt water enema misconception KGD, I didn't think that was going to work.
 
Pffft.... that all you got, Ken?....... Read a book, why don'tcha. Listen, Bear did the salty-pooper maneuver and didn't shrivel up like a jerky stick... coolness confirmed... you lose, professor.

Hey, if you have a film crew rehydrating you off camera, than his method will work fine without too much danger :D
 
Yup... seawater enima works fine if yur sippin' on a Big Gulp during commercials.
