In survival, the greatest needs for our survival are water, food, shelter, and physical and mental health care. But among all of them, the one that stands out the most is the need for water.
The first thing a survivor has to do is look for water, so that their chances of surviving are high, this is the main source of our life.
Human beings can live up to three weeks without food, but without water they will not be able to live more than three or four days, depending on their physical condition. The average amount of water eliminated by the human body in a jungle area, exposed to constant perspiration, is two to three liters per day.
In areas where water is scarce, it must be rationed, in order to try to maintain the daily water ration, since it is not known exactly how long we will be in this condition, but in the jungle and mountain regions it is not difficult to get water, since the rains are constant and there are numerous rivers, lagoons and swamps.
One of the greatest dangers that can occur is drinking contaminated water, due to the diseases they cause. The water can be loaded with pathogenic organisms, for which it is convenient to purify it, either by boiling it for at least 3 to 5 minutes, we can also use Micropur purifying tablets or add 2 or 3 drops of iodine or chlorine per liter of water and let it rest for 30 minutes before drinking it.
The diseases that can cause contaminated water are: Dysentery, Typhoid, Paratyphoid, Malaria, Cholera and Parasitosis.
Water can be obtained from a muddy swamp, even if it has a bad smell and is unpleasant to the taste, but it will need to be boiled first. To determine if the water is not contaminated, add a bit of sand, and if it sinks quickly, it is ready to be used, but if it does not sink easily, it is a sign that it is very dense, therefore, it is impure.
On rainy days, the draining of the trees can be used, the water runs along the branches and then descends through the main trunk. It is possible to cut this current using a garment tied on the same trunk, to drain it later or to guide the water by wick effect, towards a container.
Plants where you can get water
Coconut: It is convenient to look for green coconuts because they contain more liquid than pulp, but it is recommended not to take too much, since it is also a powerful laxative.
The Bamboo: Generally these plants contain water between the hollow knots.
The Sour Cane: It abounds a lot in the tropical forests, it contains abundant pleasant acid juice.
The Banana: The banana stem contains abundant water, for this an incision must be made in the lower part of the stem.
The Lianas or lianas: To obtain water from them, first you have to cut the highest part and then quickly, the closest to the ground. The piece should be 1.5 meters to facilitate handling. The water from these lianas has a transparent color and a neutral or fruity flavor. If an incorrect vine is chosen, its liquid will be milky or thick and its taste will be bitter or spicy; in this case we must discard it because it is highly toxic.
The water collected from the plants should not be stored for more than 24 hours, due to the fermentation process.
Observe and knowledge of fauna
On a jungle tour, watching and listening to wildlife is part of the Amazon travel experience. However, this is very useful in a survival situation. For example, if we follow the tracks or traces of some mammals, they can lead us to a water source. The birds usually fly towards a water source in the afternoon.
In the Amazon there are different species whose songs can indicate the presence of a water source. Learning to recognize the sounds of the jungle is useful for survival.
