Imagine you are Robinson Crusoe and then ask yourself: do you know how to survive on a desert island? Of course, today the scenario would be different: a plane crash, a storm that hits the boat in which you sail, a yacht expedition that goes wrong. But the end result is the same: you get stuck on a tropical island with nothing but your strength and knowledge to help you survive. You are far from romance in “Blue Lagoon” and you have to do something to stay alive until help arrives.
You may find yourself in different situations: your plane crashed and there are other survivors or you are alone, with nothing but your clothes; You can gather things to use from your boat or boat or you have absolutely nothing to make it easier to survive.
Best case scenario: more survivors and some supplies.
Once the tragedy happened and you find yourself on an island you have never wanted to visit, you have to do something to survive.
First, take a look around and try to figure out the size of the disaster. Search other survivors, It will be much better to face the next few days together with other people. It could also be much more comforting. Ask the other people you find to help you. Some of them could be injured. Put them away from immediate danger, such as the tide or sharks (if they are still in the water).
After gathering everyone, Start to assemble all your belongings.: lighters, papers, chewing gum, everything you have could be helpful. It also gathers all the leftovers from your plane or boat. You can use wood or pieces of metal to build a shelter. It would be perfect if you could find some blankets, sheets, pillows or even medical supplies. Do not leave anything behind, do not know what use these little things can have.
You can have luck and find a cell phone. If you still have battery and reception, try to contact the authorities. Tell them the last exact place you know you were in before the accident. Using the wireless connection you can find your real location. In this case, you will only have to wait for the rescue team to arrive.
If you do not have a cell phone (which is very likely), you should make a plan for the next days. Try keep calm and tell others to do it. This is the only way you can think clearly and the only possibility of developing a good strategy to survive those difficult conditions.
Find out what jobs the other survivors have. A doctor could be very useful for wounded people seeking medical attention. It is important that they receive first aid so that their wounds do not become infected or even become lethal. Look in your supplies: see how many bottles of water, what foods and what useful objects you have.
Find water on the island.
Never drink water from the sea. Even if you are surrounded by water, drinking it can even cause death. These are the effects that seawater can have on your body:
- Blood pressure – Drinking salt water can have devastating effects on blood pressure. Seawater causes a sharp increase in blood pressure, which triggers other harmful effects in the body. High blood pressure exerts a great pressure on the heart that begins to beat strongly.
- Heart rate – To cope with high blood pressure, which occurs due to the consumption of salt water, the heart begins to beat faster and faster. There is difficulty breathing, followed by sweating and dehydration (through sweating).
- Physiological changes – After excessive sweating, dizziness, headaches and nausea followed by vomiting and bloody stools occur. These painful symptoms of the body accelerate the process of dehydration, shortening the patient’s survival time. Symptoms appear only if the sea of salt water is consumed in excess.
- Excessive thirst – And from here you get to the next stage: excessive thirst. As you become dehydrated, your body feels the need to drink water. The lips crack and injuries occur. Salt water will not help improve your condition or hydrate your body. Due to the excessive salt content of seawater, the body does not assimilate water, but salt. As such, there is no feeling of saturation but a continuous need to drink more water.
- Brain damage – The infiltration of the huge amount of salt in the body affects the entire immune system, stopping brain activity. Imbalance and delirium occur and beneficial fluids begin to decrease in alert mode.
- Loss of consciousness – As a result of salt water consumption and the physiological changes that occur after you may even lose consciousness. It is the result of the lack of drinking water and the existence of an excessive amount of salt that runs throughout the body. This thing that causes damage, sometimes irreparable, in brain function.
- Inability to make decisions – The ability to make decisions will be strongly affected by the salt of the body. The scientific explanation is that the ingestion of salt water from the sea will never satisfy you. Thirst increases with each sip and you continue to drink until the amount of salt reaches the brain. From there, delirium appears.
- Renal insufficiency – Kidney failure occurs when seawater is drunk in large quantities and for a long period of time. The kidneys are not designed to withstand this amount of salt, so inevitably a failure occurs and then the kidneys are blocked.
- Death – If you do not get professional help on time, drinking too much salt water can kill you. Dehydration, loss of consciousness, followed by kidney failure can cause death.
So, find fresh water sources. Choose some people who can look for food and water on the island. However, water is the first priority you have. You can survive up to 20 days without food, but lack of water will kill you after 72 hours.
Continue the survival preparation.
Start building a shelter With whatever material you have around. It must be strong enough to withstand the rain or the winds you may encounter. You can sleep in blankets, sheets or towels, depending on what you have available. Try to dry your clothes if they are wet and keep them that way if possible.
When the shelter is ready begin looking for food. Depending on the island you can find bananas, coconuts and other fruits. If you want, you can cook them using a coconut like your pot. This is how your meals will look for a while. Another great source of food could be fishing. You can make a stick with bamboo sticks.
Be careful with sharks while fishing. Do not leave shallow water, it is less likely that predators will come there.
You should also Stay alert not to be attacked by other animals. You really do not know what kind of wildlife there is on your island. The first nights you stay awake in turns and watch the predators that might be tracking.
Start the help signaling.. The best way to do it is to light a huge fire that can be seen from a great distance. Use twigs, small or large pieces of wood, anything that can burn is good and place the tinder in the middle. If you do not have lighters or matches, try lighting the fire with glasses or other lenses to concentrate the sun’s rays on the tinder.
There is a possibility that the lenses are also not available. Then you should use the “Plow of Fire” method:
During the day, add some wet wood and leaves to the fire. The thick smoke will be noticed by any plane or boat that passes nearby. You can also write SOS in the sand with the help of some large branches. The letters must be large so that they can be seen from the air.
After doing all this, wait for help to arrive. The waiting time can be more pleasant if you can fill it with enjoyable activities such as mental or sports games.
The worst possible scenario: alone and without supplies
The most important thing for you is keep calm and analyze the situation. The STOP “STOP” device is perfect for you at this time: stop, think, observe and plan. You will have a better chance of surviving if you do not get scared.
It is too late to regret that he has not taken a first aid course or that he has not brought the medical equipment. There is no doctor or ambulance, there is no hospital nearby. You have to do something. Try to give your best with what you have at hand. It does not make sense to stop smoking, surrender or die. If you have a strong will, you can escape alive.
In a survival situation, you will have to use all your bodily and mental abilities. You have to face many tensions: fear, pain, illness, injury, cold and / or heat, thirst, hunger, fatigue, lack of sleep, boredom, loneliness, isolation. You’ll have to be able to resist all that.
In a crisis situation, the first step in the struggle for survival is prioritize and decide what the first emergency intervention should be. Always highlight problems and order them hierarchically. You can not solve them all at once.
For survival, some basic conditions or needs are necessary: air, water, food, fire, shelter. The proper functioning of the human body can stop (and death occurs) and this can be caused by the deterioration of health (wounds, shock, hemorrhage, respiratory arrest, crushing, serious diseases, etc.), lack of water, food, cold or excessive heat.
First, Examine yourself for any possible injury. The most urgent thing is to perform the first medical assistance: stop the bleeding, stabilize the acute problems, so that you can take charge of the whole situation.
The next thing to do is find water. There are many sources of fresh water:
- Rain: collect it using any container you may have, such as coconuts, large leaves, tree holes or rock gutters. If it looks like it’s going to rain, dig a hole in the ground and align it with a sheet of canvas or plastic if you have something at hand. Or with oiled paper, sheets, etc. Its use can prevent any leakage of water in the soil that is as thirsty as you are.
- Waterfalls, springs – you can find them inside the island.
- Dew – you can pick it up from the leaves
- Still solar – if you have a piece of approx. Plastic sheet of 80 x 80 cm, you can try and # 8220; milk and # 8221; ground. The method does not always work, but sometimes it can even produce more than 0.5 l / day.
- Dig a hole with the upper diameter of approx. 1 m It must be deep enough to fit a cube in it. Stretch the plastic over the hole and fix its edges with dirt or rocks. In the center of the sheet put a stone that will give a cone upside down. The bucket or collecting container will have its mouth about 5 cm below the top of the cone.
- The sun will heat the walls under the plastic, forcing the evaporation of water from the ground. When the air under the plastic becomes saturated with water vapors, drops of water will appear on the surface of the film due to condensation, since the sheet is cooler than the air below it. The drops will fall into the container. Sunlight is also working at night, because the floor is hot and the sheet is cold. All you need is patience.
- Rub the bottom of the sheet with sand and the water droplets formed will flow more easily, but be careful that the surface of the film remains clean. If you have a hose, a pipe or a stick, you can place it on the end of a bucket. You can suck the water through the pipe, without removing the plastic.
Build a “Lean-To” shelter
or a “tepee” shelter:
The next step is start a fire so you can be found and searched Food or go fishing.
Being rescued – You have 2 options:
- wait for help to come to you
- leave the island for help
There are some facts that you should keep in mind: all airplanes are strictly controlled, so if something happens to them, the authorities immediately begin the rescue search. Boats in difficulty are searched only if they have launched the SOS signal.
The decision to leave the scene of the accident instead of sitting and waiting for help is of vital importance. They must analyze together all the factors on which they base their decision. Your choice should be made with good judgment because the two alternatives have advantages and disadvantages. For example, if you sit and wait, you save your power and energy. Instead, on the way you will need a lot of will and audacity to continue.
If he is forced or decides to leave the desert island, he could have problems. You can consider the island as a place where you can get food and water and it is potentially safe. Before deciding to leave consider the following questions:
- Are you healthy enough to go through the whole trip? He does not know how long it can take to reach someone who can help him.
- Are you completely sure that there is no possibility that any plane or ship will find it?
- Is there any real chance of being seen at sea? Because the only way out of the island is by raft.
If your answer to all these questions is “yes”, then you should start planning your trip.
Build a raft – The best way for the raft is the rectangular one. The raft for a person must be approximately 3 to 3.50 m wide and 1.50 m long and must be made of trunks or trunks approximately 15 cm thick.
Here is how you can do it:
Drink everyone supplies you think you’ll need: fresh water (as many containers as you can carry), food, clothes, something that protects you from the sun’s rays. You really do not know how many days you’ll spend in the water.
You never know where life will take you. At this moment you are sitting comfortably on the plane, watching your favorite movie and the next moment you can be on the seashore, with no one at your side, without food or water. This may be the key moment in which your decisions will determine whether you will survive or not. All up to you. You will survive with calm, little knowledge and good judgment.
