| Benefits of Dehydration?
Posted: 11/6/2009 2:36:10 PM | Hello,
For the past few years I have been doing some forestry work and am often working in very remote and isolated conditions. The work is very physically demanding and the shifts long, and always open ended(a 5 day contract turned into 29 straight).
In the past I have heard about some military units such as the french foreign legion, that train their troops through a constant state of dehydration. It is something I have been 'practicing' during my work season and was surprised to see how much I could actually reduce my water intake (and food to a degree)during the day without noticing serious or even moderate effects of dehydration.
I am wondering if anyone has had any experience or has any information to offer on this subject.
Google has provided me with many sites about it's negative effects but nothing on it's potential benefit or it's long term negative effects.
Thanks

As long as you do not get thirsty then you are not dehydrating too much.
If you felt thirsty then you would have been feeling the effects.
I do not know of any advantages you would gain as water is a vital fuel and restricting its intake is going to hurt your performance.
Your body needs "x" amount of water to do "x" amount of work and if you are not giving it directly it is going to take it from somewhere else and at some point you will need to replace that.
I am wondering if anyone has had any experience or has any information to offer on this subject.
Yep.
I was delivering a sail boat from Cape Breton to Halifax (~290 miles)
It ended up being a 24hr trip of pounding into 20ft and 30ft swells in the fog and rain.
I puked so much I ended up losing ~12lbs.
It took me 4 days to recover.

That should be telling you something. | |

So for the past 15 years I drink very little during the day in the summer month when I work... I don't have any problems... I have heard that it can cause kidney problems in some people though... | |

To be fair, I think most of the population is dehydrated all the time. Not enough people are drinking enough water. | |

It's highly dangerous and can cause kidney damage amongst other things.
It's abusing the body. | |

Posted: 11/9/2009 12:23:17 AM | | lol.. maybe asthetics? body builders only do it for their skin to tighten before competitions.. that's the only upside.. as with regards to your health? lmao no. not one benefit. ur body will just suffer and won't be able to function properly. it won't be able to transfer nutrients to ur muscles properly, ur muscles won't be able to get rid of lactic acid and they will become permanently damaged and organs will start to deteriorate. they maybe used that method for them to become use to being in such bad shape or pain.. so basically for pain and thirst thresholds. not any physical leverage. | |

Concentrated urine causes crystallization and formation of kidney stones, which is why nephrologists encourage plenty of liquids.
You're welcome to form kidney stones and get back to us whether it's "negative effect" :)
That said, there is no scientific study recommending the famous 8 x 8 0z of water per day.
Excess water is poisonous to the point of death.
The best liquids are from fruits and vegetables with are about 90%+ (nutrient-laden) water, not corporate bottled water.
If you're thirsty, drink (or have a fruit/vegetable salad). | |

Various types of sugars often interfere with the body's natural electrolyte absorption processes.
Despite many years of researching the water intake thing , I can't find any conclusive,
100% positive , absolute evidence from any medical/scientific/athletic journal that
says beyond a doubt you need X amount of water per day.
I kayak wide open water many,many miles from shore
- we don't exactly easily just run to shore to piss .
This is actually real, real important to us sea kayak folks - whizzing in the wet suit is a sin !
Prolonged hard exercise will actually shut down the kidneys a bit, reducing urination.
Marathon runners quite often weigh more at the finish line from drinking excessive water.
Moderation is definitely a key factor with water/electrolytes playing a key role in performance.
Estimates are that our liver stores about 400 kcal worth of glycogen
and that our muscles store about 1400 kcal worth.
During exercise, the muscle glycogen is the preferred source and the
liver glycogen is secondary because the liver has another task
- maintaining normal blood sugar (glucose) levels,
or more specifically, guarding against hypoglycemia.
Drinking fluids allows around 300 kcal per hour based on common consumption.
Generally assume 2 1/2 hrs max if we get our energy from consuming 300 kcal per hour
of sports drink and deplete the glycogen stores from our muscles and liver.
Pedialyte contains dextrose, fructose and minerals aka electrolytes.
It has sweeteners like ace K (acesulfame potassium) and sucralose, avoiding sugar or sucrosre.
This allows Pedialyte to be relatively low in calories and carbohydrates.
Scientists claim carbohydrates are handled fairly easily by our bodies.
They are converted quickly to glucose and used for energy or stored as fat.
For fructose to be metabolized, the body has to create both fasted and fed conditions.
Eating a lot of fructose will really cause your liver to work hard.
Gene-expression analysis showed that Both insulin-responsive
& insulin-repressive genes are induced during this process
Many Americans consume large amount of Fructose.
Refined sugars such as sucrose or table sugar (which is half fructose) and in
high-fructose corn syrup, used in soft drinks, protein bars, and fruit juice, etc., etc.
Published in a recent issue of Biochimica et Biophysica Acta
University of Illinois at Urbana-Champaign (2008, December 11).

Posted: 11/10/2009 7:08:11 AM | That just sounds dangerous to me. I want my organs to last all my life.
I think I walk around in a constant state of dehydration. I'm always looking for something to drink.
I keep cases and cases of water in my car, in my house, in the back room at work, etc. | |

Posted: 11/10/2009 10:53:00 AM | | Dehydration is the evil to your muscle. It can cause rips, tears, and strains due to dehydration. So not sure why one would see a benefit. Now for the military, maybe they want them to experience it so if on battlefield they know what to expect? | |
