Answer 2

People have survived without food for weeks or even months, but go without water for even just one day and you will be in desperate need.

Knowing that water is by far the most important nutrient for the human body (besides oxygen), just how long can the human body survive without adequate water?

To maintain a high level of health and efficiency even in ideal environments, a minimum of two quarts of clean water per day per person is the generally accepted rule of thumb. In very hot or cold or very dry environments, or if you are physically active, two quarts of water a day may not be enough to sustain life over a period of days or weeks.



Fresh Clean WaterWater lost through sweating and normal respiration must be replaced in order to stay healthy and function at top efficiency. Water is also needed to process the food you eat, especially if it is salty or you eat heavy foods like meat.

In general the higher the temperature the greater your water consumption needs to be. If you are active or exposed to the hot rays of the sun you may need upwards of a gallon of water per day to stay to healthy.

Perhaps surprisingly, very cold environments can be as dry as the driest desert. This is because cold air cannot hold much moisture. This cold dry air serves to dehydrate your body with every breath you take. Cold dry air can also rob your body of moisture via loss from exposed skin. This is one reason why your lips may be prone to chapping. So during cold weather even though you may not be sweating nearly as much as when you are in a hot environment you may still easily become severely dehydrated without even realizing the danger you are in.



For the average person in an average day at home, three days is the limit.  But for somebody who is exposed to very cold or hot temperatures, or who is very active, the length between drinks is much shorter.

Answer 3

the first answer was correct 3 days and you can survive 14 days without food before your body starts to eat itself.

Answer 4

around 3 days, depending on how healthy you are.

Answer 5
