ART OF SURVIVAL #4:Water Procurement


More than three-fourths of your body is composed of fluids. Your body loses fluid as a result of heat, cold, stress, and exertion. To function effectively, you must replace the fluid your body loses. So, one of your first goals is to obtain an adequate supply of water.

Before we discuss how to obtain water,here are some of the fluids which shouldnt be replaced for water:

1]Alcoholic beverages: Dehydrates body n adds to your woes incase you are thirsty

2]Urine:Contains body waste.Has over 2% salt.

3]Sea Water:Is about 4 percent salt. It takes about 2 liters of body fluids to rid the body of waste from 1 liter of saltwater. Therefore, by drinking seawater you deplete your body's water supply, which can cause death.

4]Blood:Is salty and consider a food; therefore, requires additional body fluids to digest. May transmit disease.

5]Ice:Ice shouldnt be eaten without melting.Eating ice drops your body temperature and might worsen your condition if you are stuck up somewhere.

Environment:Frigid areas

Source: (Snow and Ice)

Technique: Melt and purify the water

TIPS: Do not eat snow/ice without melting! Eating snow and ice can reduce body temperature and will lead to more dehydration.
Snow/Ice can be impure.Purity of snow is equal to purity of water from which it is formed.Sea ice can have salt content

1.Desalinating.Boil salt water with a shirt suspended above the boiling water, which absorbs the steam leaving you with a shirt full of potable water. wring out and drink..
2.US special forces carry portable seawater desalinator kits.Dont know if they are available in market


Catch rain in tarps or in other water-holding material or containers.More on rain water catchment later...

TIPS:Do not drink seawater without desalting.
