How to get water ?

Water is the second important element in a state of survival. If we just spend several days without food, we do not spend more than a day without water, our body becomes dehydrated. Summer and winter, look for the running waters of streams and rivers flowing into the valleys. There are drinking water in all regions where the population is sparse and there are no places where water is contaminated enough to cause death. The contamination usually occurs in the vicinity of towns and villages, where one rarely used survival techniques.
If we do not find running water, here are some ways that can be used to purify water: Boil water for 3 to 5 minutes, allow to cool before drinking, then agitate for oxygen. We just get water by digging one or two meters from a lake or a river doubtful. Water filters and will filter by passing through the sand. You can also retrieve soil moisture using a polythene (see illustration). You can also t'abreuver with the sap of certain trees (birch, maple) or with water from rain or dew. In winter do not eat the snow, it has the opposite effect, it tends to dehydrate us. Better to melt in a saucepan or in his hands.
