Man is more than 75% water.
This fluid performs a lot of functions in the body, so it
should regularly receive the required amount of water.

How long will you live without water, is it true that you die through
a week?
Before you answer this question, you need to understand
what exactly water needs a man.
In the body, water performs the following functions:
1. Supports all human systems and organs in the workplace.
condition.
2. Regulates the overall body temperature.
3. Dissolves oxygen so that a person can breathe.
4. Displays digested foods after metabolism.
5. Helps in transporting vitamin, mineral and various
trace elements.
6. Promotes detoxification.
7. Makes muscles contract.
8. Carries electrons throughout the body.
9. Does not allow dehydration, thanks to which the brain
can function normally.
If a strong human health put in good
climatic conditions, then on average, without water he will be able to live
seven days. At the same time every day his condition will be
to deteriorate.
Primary signs of dehydration (stage 1)
are:
• feeling of dry mouth;
• feeling of thirst;
• dark urine.
In the second stage of dehydration (2-4 days) in humans
The following symptoms may occur:
• itching and dry eyes;
• joint pain;
• disturbance of a rhythm of heartbeat;
• weakness due to slower blood circulation;
• diarrhea.
In the last stage of dehydration, a person suffers from
such manifestations:
• complete cessation of urination;
• nausea;
• drowsiness, confusion of consciousness, aggression and other
disturbances in the central nervous system;
• lethargy;
• shock;
• blue skin and death.
When severe dehydration is broken blood density and its
fluidity. Because of this, the kidneys, heart and brain suffer greatly,
that most need nutrients.
In addition, with excessive blood density in the body will
do much less oxygen (cells cannot quickly
to transport oxygen through the body). It is for this reason that without
water man will live less than without food.
How many people can live without water?
According to research, an untrained person with
air temperature of 18-20 degrees can live without water around
eight days. At the same time, the situation changes drastically if the organism
will remain without water under the scorching sun. In that case, he
can live no longer than four days.
Famous scientist E.F. Adolph studied environmental effects on
the rate of excretion of water from the body. He found this:
• if a person is in the shade at a temperature of 16 to 20
degrees and not engaged in physical activities, he may not
drink up to ten days;
• if a person is at a temperature of 29 degrees, then he
live without water for up to seven days;
• at a temperature of more than 35 degrees without water a person can
live no more than two days.
In addition, if during dehydration a person is also actively
moves, then it will quickly lose time, as when working muscles
The rate of water consumption by the cells increases significantly.
Such indicators are justified by the fact that in just 1 day
hundreds of liters of water flow through the human brain, and through the kidneys and
more than that. This allows all systems to work smoothly.
When a person does not receive the required amount of fluid, then
he is rapidly losing all the minerals necessary for life and
trace elements. Thus, tissues and nerves do not receive “food” for
livelihoods and die off.
In 1985, a nine-year-old was found under a destroyed building.
the boy who stayed there for thirteen days without food and
water. After the rescue, the child survived and was able to recover.
Another incredible incident was recorded in 1947, when
rescuers found a 53-year-old man in an abandoned house.
The victim was without water and food for sixteen days.
According to the Guinness book, it was possible to live the longest without water
an Australian who was locked in a cell by the police and forgot
that he is there. That person was imprisoned.
Eighteen days in a row without food and water and remained alive. Secret
this phenomenon is simply explained: it was damp and cold in the dungeon,
therefore, the body did not lose moisture so quickly. Only this fact saved
prisoner from an early death.
These facts indicate that, despite the statistics,
in an emergency, the human body can even survive
the most difficult conditions.
How long you live without water depends on what
engage
It is important to know that water from the human body can
not only through urine, but also through sweat
discharge, and even breathing. On a sunny day at air temperature
27 degrees in an adult along with sweat in just one day
выходит до одного литра water.
Because of the intense heat the body temperature all the time increases
so if there is little fluid in the body, then a person can
easily die from overheating or heart attack. The water plays
the role of cooling. It keeps the temperature normal.
Like any living thing, the human body is always
works (even at night). As a result, he constantly needs
beneficial trace elements and fluids. For normal
the functioning of all systems, a day you need to drink at least two
liters of water (not counting juices, compotes, soups, etc.).
In addition, if a man or woman is active
physical activity, they need to drink more water, because
fluid flow will be faster.
In case of accidental contact with an emergency situation in which
there will be access to water, you can use the ancient method
survival. It consists in putting in the mouth rounded
pebble. At the same time you need to breathe through your nose, not your mouth, so that your body can
more moisture was stored. Thus, pebble sucking will be
promote saliva secretion and help temporarily forget about
thirst.
You should always maintain a normal fluid balance in
because water is the basis of life.
