If you really live in the wilderness, then: water is definitely the biggest factor in determining how long you can live. Not only must there be water but also clean and sterile fresh water.
Without food, a normal person can live for three weeks on average, but can't live for three days without water. The average person consumes 2-3 liters of water per day. Breathing, increased work intensity, rising temperatures, and sweating all cause the body to lose water. Water must be constantly replenished to maintain normal water balance. So water needs to be given priority. A flowing water source is ideal.
How to obtain clean, sterile and safe fresh water:
1. The first choice is to boil flowing water, such as stream water, spring water, river water, etc.;
2. If there is no fire, choose to go to the river water, spring water, and the upper reaches of the river to check for animal carcasses. If not, the water can be drunk without boiling and sterilization. .
3. If there is no stream, spring, or river water, then you can only drink the water from the pond. The only advice is to never drink this kind of water directly before you are dying of thirst. It needs to be treated (described later);
4. If you live on a desert island, then for most people, just wait for it to rain! Desalination cannot be explained by a small experience here.
In this step, let’s talk in detail about what the most basic tools can do in the field. Let’s assume that only dirty water, a knife and a lighter (we don’t worry about getting fire from wood, but it’s possible to get fire from glasses). In extreme environments, first raise the fire. When the wood is not completely burned to ashes, let’s take it out (commonly known as charcoal). A layer of charcoal and a layer of fine sand is the best way to filter the water. Physical methods of debris and bacteria.
Physical water purification alone is not enough, because charcoal and fine sand can only filter impurities and most of the bacteria, but they cannot filter out the bacteria 100%. In this way, the water must be boiled with fire. How to cook this wilderness, don’t worry. , First of all, I must tell everyone a common sense: as long as it is a water-tight container, it can basically be used to boil water, such as mineral water bottles, paper cups, etc., as long as you fill up with water and burn it on the fire, they will be deformed but in the end they will be able to Bring the water to a boil, if it doesn't work, try it right away.
You might say that there are no paper cups and no mineral water bottles in this wilderness, what should I do? There are many ways to teach you a unique skill (it is definitely feasible)! Find a piece of wood and use a knife to hollow it out. The principle is that the water can be filled without leaking. This is not enough, otherwise it will not be an exclusive invention, because at this time it is very likely that the wood will be burned before the water is turned on. We need to make peace. A layer of thin mud is applied to the outside of the wood, so that the mud hardens to protect the wood as soon as the fire is roasted, so that as long as the mud is on the wood, it will not burn, and a wooden-backed clay pot is produced.
At the same time, in order to minimize water consumption, the following measures can be taken: a. Rest more and exercise less. b Don't smoke. c Stay in a cool place. If you can't find it, you can build a pergola. d Don't lie on the hot ground. e Do not eat or eat as little as possible. If the body cannot get water, body fluids will be transferred from vital organs to digest food, which will accelerate dehydration. Fat is difficult to digest and requires a lot of water. f Don't drink alcohol, which will consume a lot of water in the organs. g Don't talk-don't breathe with your mouth.
To sum it up, fire and knife are your second life in the wild. Without these two things, you may not die right away, but basically you won’t live for long. This is not alarmist, so it’s good to bring a lighter and a knife when you go out. Things to do in the wild.
