How Long Can A Man Live Without Water?

abminara
Well, I've been doing some research about this, and some sources said that a man can only live up to 3 days without water, very few said about 5, and one said that a man can live for a whole week without water, then lose conscience, and live in that condition for another week while his heart and lungs still work. What do you think?

Wow... I've never encountered those sources. I know, however, that, on the average, humans can live for only 2 days without water. I doubt anyone can live without water for 5 days, much less, two weeks.

You coorect usually 3 days is the max for anyone to live without water, but I don't remember if the body starts shutting down or you just drop dead though. I found this interesting quote and I believe it is the most accurate of pictures with how long you can survive without water, "3 hours without shelter, 3 days without water, 3 weeks without food." After reading a couple of articles it would see that a slow shutdown of your body is the most likely course as dehydration sets and starts ruining some organz and such, but of course I don't think anyone would test that theory though but growing up I always heard 3 days.

Thanks. This is actually a way voluntary death is brought to life in several countries (where it is legal and hospitals are allowed to help you die if you want to). But the article said that a person can survive for almost 2 weeks - I doubted that, that's why I asked.

I went 2 days w/o water on accident once, and I was at work, and all the sudden my hands fell asleep (exactly like how you feet or legs do from lack of blood), it was on Black Friday no-doubt, and I work as a salesman, (so you know), it was freaky, but once I downed about 3 cups of water I was fine shortly thereafter. Its pretty scary when you can't feel your hands, you get dizzy from the simplest motions, and walking is tiring.

I think that's a rather inaccurate quote... Some people in our country have lived entire lives without shelter. Also, people can last up to two months without food. As for the three days without water... I think 3 days is the point where the dehydrated person dies, not where his body starts to shutdown. I could be wrong, though, lacking the initiative to back up my statements with verifiable sources at the moment tongue.gif

perhaps stmike is supposed to say "3 minutes without air" instead of "3 hours without shelter", at least when it pertains to Nature's 3-3-3 survival rule -- air-water-and-food in the sequence of surviving without, in timeframes of minutes, days, and weeks. the "3 hours without shelter", though not in the usual 3-3-3 quote is a generally accepted rule -- in extreme hot or cold conditions. another similar rule exists pertaining to 3 minutes in freezing water before hypothermia sets in.

I dont really know how long a man can survive without water. But i have heard of something crazy like this.


There is a village at north america ( if i remember correctly !!! ) occupied by some native tribals . And the water over there stays highly contaminated. So, the locals use some kind of a plant juice for all their needs . i.e, they take a liquid from these plants and use it as a substitute for water.

As i had seen it on a footage on a television channel, i do not remember the exact name of the village. But, if it is true, then a man could live for his whole life span without water, provided he has a substitute for it.

How much time a man can live without water is depends on many factors. For a healthy man, main factors are environment temperature and relative humidity.

If environment temperature is high, it will cause more water losses from body and lead to early die. But if the temperature is normal, it will cause less water losses from the body and the person will survive more.

Again if relative humidity is low, it will cause more water losses from body and lead to early die. But if the relative humidity is normal, it will cause less water losses from the body and the person will survive more.

In general, one person can survive 2 to 10 days without water depending on the rate of water loss from the body.

So, I think 3 days, 5 days, 7 days all data is correct depending on environment where the experiment is done. If this experiment is done in a hot low humidity area, the person will survive less time than a high humid and normal temperature area.

I always found this question quite interesting, so I decided now to do a bit of research by myself.
Most of the answers here seemed a bit speculative, so I thought I should turn to a somehow 'authorized' source.

From wikipedia, a page about survival skills:
'A human can survive a maximum of three days without the intake of water assuming you are at sea level, at room temperature, and a relative humidity'.

These conditions are the most favourable for 'without water' survival, wereas colder/warmer temperatures, different humidity just decrease the period.

You can also survive more if you prevent water loss.
And, from the same page, the record:
'The crew of a lifeboat reportedly lasted 8 days without water'.

in cooler places you could live more in hotter places you go unconscious faster.
2 days without water seems you could even 3-4 ...but that's not for everybody... if you're enough hydrated and stay in a cool enough place not in the sun you could survive more...if not you'll die most probably in the second or the third day.
Also is a sure thing that if you keep thinking about the last time when you drank enough water and you were well hydrated you can fool your senses and think that there is no problem... I don't recommend to try something like this because you can loose your consciousness and you'll be unable to call for help, anyway I daub that is somebody willing to try this laugh.gif

I was always told that you can live without water for 2 days.
But I began to doubt when I didn't drink anything for almost 2 days and I only had huge headache and felt weak.

So I think you can live 3 days with out water.

Well, I would say 3 days is the time where you drop dead because let's analyze it logically... Your body is made up of 70% water, you need around 1.5 - 2 liters of water daily, all metabolic reactions in your body require water, all your other body functions require water to be present, your blood is made up mainly of plasma (which is basically water)... so if you do not supply your body with water, soon your body functions will stop, your metabolic activity will cease, your blood pressure will drop, and finally within 3 days maximum you will drop dead lol! So yeah, I believe it's 3 days maximum and 2 weeks is tooooo much!! I strongly doubt that a man can stay alive for 2 weeks without drinking any water!

    symbols, themes and motifs. To fully comprehend the novel, an individual must read it more than
    once. Nathaniel Hawthorne uses very vivid imagery, yet the story unfolds quite slowly. One should
    have much patience while reading this classic, though in the end one will get rewarded. The Scarlet

    there is no such post. In 2005 the Legislature cut the position however they did not cut the funding

    F. Scott Fitzgerald’s The Great Gatsby is much like an onion. On the surface there is the hard outer

    Great Gatsby Fitzgerald portrays a romantic love between a man and a woman, but inside the real
    meaning is much deeper. Fitzgerald depicts the 1920’s as a time of decay social and moral values,
    evidence of this is the greed and the pursuit of pleasure. Jay Gatsby’s constant parties epitomized
    the corruption of the American Dream as the desire for money and worldly pleasures ov....

    Germans. Throughout the duration of the book, Paul Baumer, the main character, is portrayed as a
    once innocent adult that becomes emotionally desensitized by the war. The goal of All Quiet on the

    nutrients. Animal body contains more than 70% water. So all animal (including human) needs
    sufficient water for proper functioning of their body. How much water intake is required per day
    for an animal is not fixed. The intake of water depends on body size, level of activity,
    temperature, humidity, and other factors. The more water loss from the body results more requirement
