Is it possible for the human body to absorb H2O through the skin being submerged, to live without drinking?

Ok, although the oil and dead cells on the surface of your skin are intended to restrict it as much as possible your skin is very slightly permeable to water.  If you were submerged totally in fresh water you would still dehydrate and die if you didn't drink, but maybe at a slightly slower rate than you might do otherwise.  Because of the osmotic potential of salt water you would probably LOOSE (a very small amount of) water from your tissues to the surrounding water!

It is true, the value of the water is less than the harm done by utilizing body heat to melt it to a usable liquid. You need both heat and water to survive, but you will die quicker of exposure than thirst. Where there is snow there is almost always liquid water, water will pool in low lying areas, and the snow above it acts as an insulating blanket keeping it from freezing. Hydrating yourself will help your body function better, and keep you warmer, just don't hydrate at the expense of lowering your body temperature.\nSurvival is often times a simple cost/benefit analysis, making well thought out decisions combined with a bit of luck can save your life.

Ok obviously this is for a class - so why don't you consult your text book.  The answer will be in there.  Think about it logically too - your skin, in an of itself is a natual barrier.  It is made of tightly packed cells that are keratinized to prevent too much water getting in.  Get the drift...??

Water is required for the following for the body:1.for tissues, and for the blood, 2.for producing digestive enzymes, and lubricating fluids 3. for excreting the waste proucts from the body through, urine, motion, sweat etc.4. To make the body cool by evaporation by sweating  In additon to the water in the food we take about 1.5 to 2 litres is nececessary  for normal  adult.( In our body the water is 2/3 of our body weight)

I think when plant absorb water, or H2O, they use the H, or the hydrogen, and aspirate (or "exhale" in animal terms) the oxygen they take in as a liquid as a gas. The aspiration I believe is very slow and could take 100 plants 100 years, longer than the average lifespan of a human being, to see significant increases in oxygen levels.

??? i think it would vary depending upon how long someone can hold their breath, what type of situation it was...like, if someone were being violently drowned, they may suck in water making it quicker. same with drinking. being inebriated may decrease the time if the person was less in control of bodily function.... why are you asking.....

Because the skin cells absorb the water. Its not harmful and will return to normal very quickly after you dry yourself off.

Humans can survive for several weeks without food, but for only a few days without water. A constant supply is needed to replenish the fluids lost through normal physiological activities, such as respiration, sweating and urination. Water generated from the biochemical metabolism of nutrients provides a significant proportion of the daily water requirements for some arthropods and desert animals, although it provides only a small fraction for humans. There are a variety of trace elements present in virtually all potable water, some of which play a role in metabolism; for example sodium, potassium and chloride are common chemicals found in very small amounts in most waters, and these elements play a role (not necessarily major) in body metabolism. Other elements such as fluoride, while beneficial in low concentrations, can cause dental problems and other issues when present at high levels.\nVR

I hope that youre serious....yes, you can...I dont see why not. Your glands does not stop functioning just because youre underwater. In fact, I believe that you even sweat underwater. (",)

All sorts of factors affect the suitability of the human body fluids to sustain life; these include properties like temperature, salinity, and acidity, and the concentrations of nutrients such as glucose, various ions, oxygen, and wastes, such as carbon dioxide and urea. Since these properties affect the chemical reactions that keep bodies alive, there are built-in physiological mechanisms to maintain them at desirable levels.\n\nHowever, it should be noted that homeostasis is not the reason for these ongoing unconscious adjustments. Homeostasis should be thought of as a general characterization of many normal processes in concert, not their proximal cause per se. Moreover, there are numerous biological phenomena which do not conform to this model, such as anabolism.

Heavy water is deuterium oxide, or D2O or 2H2O. Its physical and chemical properties are similar to those of light water, H2O, but the hydrogen atoms are of the heavy isotope deuterium, in which the nucleus contains a neutron in addition to the proton found in the nucleus of the hydrogen atom. This isotopic substitution alters the bond energy of the hydrogen-oxygen bond in water, altering the physical and chemical properties of the substance. Gilbert Newton Lewis isolated the first sample of pure heavy water in 1933.\n\nNow D20 tastes almost exactly like H20. However, seeds will not sprout in heavy water, and when rats are given heavy water exclusively, they die of thirst although glutted with water.\n\nHeavy water present in ordinary water has been found to be extremely harmful to living organisms in many ways. For example, if a chemical reaction in a cell produces as much energy as it consumes, then the cells will become self-sustaining, neither growing nor dying. This level is referred to as critical mass and is analogous to the approximate age of 20 in human terms. This is the age when the body is most stable and physically perfected.\n\nHowever, deuterium oxide causes cellular metabolism to operate at reduced rates because its higher atomic weight slows down chemical reactions. In our cells, this dampening effect is the equivalent of aging (and eventual death) and begins naturally after the age of about 20. Deuterium accelerates the effect, leading to cellular putrefaction.\n\nGiven that we absorb heavy water by drinking and bathing (two thirds of our bodily water is absorbed through the skin), in the ratio of 1 drop for every 6000 drops of ordinary water, we see that such an accumulation would cause definite negative effects in the body. And unlike short-lived laboratory test animals, our longevity makes us increasingly vulnerable to cellular aging.\n\nIn addition to dampening the chemistry of cell metabolism, heavy water also impacts cell division, or mitosis.

Depends on whether they are hooked up to an IV, etc.  Ther eis no set time frame but generally a person can survive without water for only a couple of days ... no simple answer to your question.

yes.\n\nEverything you injest goes to your fetus.  For that matter, things you absorb through your skin can pass to your fetus, as well as what you breath.

Not very much.  The water pressure on your body would prevent you from being able to bring in air that is at normal atmospheric pressure.  You need a compressor on the surface and a hose to breath from.

Excellent question. It is possible. I assume you mean the solid form of water (ice). It is theoretically possible. At this time finacially impossible. You would lose a percentage of the surface area of the ice by sublimation. How do you propose to freeze the water to begin with? How will you keep it frozen (remove absorbed heat energy)? Where will your source of water be? If you are taking water from Earth, how will you get it into space?

You'll only lose water, so there will be an initial drastic loss, but once you drink water, your body will absorb it again and the weight will come back.  If you don't replenish the fluids, you risk damaging your liver and kidneys along with a constant thirst.  It's not a healthy or lasting diet alternative.

Even so water will still evaporate over time if it is in a room with a  high temperature. To obviously stupid answer is somebody drank it!!!
