    You can only survive for about three days without water. I would advise against putting this theory into practice

    according to national geographics "worst case scenario" a human only have 24 hours of survival without water in a desert.. but normally as what nevet's research has, a normal situation can make human to have a 3 days of survival. for those people "who are highly knowledgeable" in here you can watch nat geo for more info...

    You would live about 3-4 days without water if you were not getting it from any other source, such as food or other beverages. Rule of 3's/

    3 minutes without air
    3 days without water
    30 days without food

    Each day, on average, some two quarts [2 L] of water is eliminated through the skin, lungs, intestines, and kidneys. We lose approximately one pint [0.5 L] of liquid every day just by exhaling. If this water is not replaced, we will become dehydrated. Some signs of dehydration are headache, fatigue, muscle soreness, dark urine, heat intolerance, and dry mouth and eyes.
    if you are fat i give you 5 days less for lighter people.

    You can't survive more than 3 days without water in normal conditions.

    You would be lucky to survive more than 24 hours in a desert.

    Its not just the lack of drinkable water that kills you on the desert...
    We have salt in every cell of our bodies - about 250 grammes (a cupful) in an adult human. That’s why our tears and sweat taste salty.

    Salt plays a crucial role in keeping our bodies functioning properly. When we exercise, when we’re hot, and when we’re going through physiological changes, such as pregnancy or growing old, its role becomes even more fundamental. Most crucially, it maintains the balance of our fluids, which carry oxygen and nutrients around our bodies

    The two elements of salt - sodium and chloride - each play a variety of crucial roles in our bodies.

    Sodium:

    * enables the transmission of nerve impulses around the body, regulating the electrical charges moving in and out of the cells
    * controls our taste, smell and tactile processes
    * helps our muscles - including the heart - to contract
    * is key in the operation of signals to and from the brain.

    Chloride is key for:

    * the digestion process
    * preserving the acid-base balance in the body
    * absorbing potassium
    * helping the blood to carry carbon dioxide from respiring tissues to the lungs.

    The body is able to adjust to the amount of salt that we consume, such as through making us thirsty when it needs extra water to dilute the salt. A healthy body processes just the amount of salt it needs and the kidneys dispose of any excess.

    Without enough salt, our bodies cannot perform all the vital functions listed above. Symptoms of insufficient salt include muscular weakness, muscular cramps and, in the extreme, heat exhaustion and heat cramps. Severe salt deprivation can even prove fatal.

    Even with water you won't last long as your system requires salt.
