If you sense that the ship you are on is sinking ...... don't freak out, there is no time to lose! Hurry up and gather as much water and food as you can and prepare life-saving equipment (life jackets, life rafts, inflatable lifeboats). If you still have time, take a few extra things that might save your life in a pinch:
Flashlight
Batteries
Two-way radio
Mirror
Flame signal
Sunscreen
Matches
First aid kit
Of course, not every shipwreck has time to prepare for a shipwreck. Of course, not every shipwreck has time to prepare, so if you don't have the above resources to utilize them to the fullest, we recommend that you grab any lifesaving "straws" before you hit the water - floating shipwrecks, drifting objects, etc. Either way, use them to save your energy and find the nearest land as soon as possible.
Looking around at the ocean, it's scary to think that it's so vast that the biggest test will be your ability to cope with it. The biggest test of your mental capacity is your faith. At this point in time, faith is gold, despair will not help, think about the future, do not be knocked down by cowardice. Keeping a clear head is the most important weapon you can use to get out of danger - perhaps it's time to remember what we're about to tell you about the rules of survival.
Once in the water, the first thing to do is prevent hypothermia. This is because the body loses heat much faster in water than in air. Mild hypothermia can cause shivers or goosebumps, while in severe cases, blood flows from the brain to the body, helping the body scramble to maintain its core temperature, which can lead to violent shivering and dizziness. To avoid this, you're best advised to put on a lifejacket before escaping, and if you're soaked to the skin, you'll need to wring out the water first to warm yourself up as quickly as possible.
Dehydration is also terrible, and going without water for a few days is enough to kill you. So you should either bring plenty of fresh water with you before you escape, or rig up a desalinator in your life raft in case of an accident. If that's not an option, a little seawater is fine, although traditionally it's said that you shouldn't drink seawater because the salt makes dehydration worse and can damage the kidneys. However, some researchers have found that this is not entirely the case. In 1952, a French doctor, Alain Louis Bombard, in order to prove his own theory, crossed the Atlantic Ocean by rubber dinghy with only some fishing gear and nets, and along the way, he ate fish and plankton to replenish his protein, and drank seawater and rainwater to sustain his life, which lasted for 65 days without any harm and finally ended his life at the age of more than 80 years old. While this point is still debatable, depending on individual fitness, it's a good idea to use it as an inspiration in case you're ever in trouble.
Another problem with rafting at sea is the possibility of heatstroke, so if your life raft has a canopy, try to stay underneath it during the day. If you are unfortunate enough to experience symptoms such as increased body temperature, confusion, rapid heartbeat, weak breathing, headache and nausea, you are probably suffering from heatstroke. At this point, you'll want to try to stay in the shade, wipe yourself down with wet clothes, fan yourself, and, of course, drink water if you have it.
But if you're lucky enough to float to an island and survive, what do you do next? Read on for the next section.
If you're lucky enough to drift for a while, you'll find an island in front of you! It's as if the light of a fire in the darkness of the night is more of a surprise than a fear, and the dirt beneath your feet is now even more fragrant. After landing and taking a quick look around, if the island is uninhabited, the first order of business will be to build yourself a shelter.
If your life raft is still with you, it can serve as a temporary shelter, protecting you from the elements and from scorpions and snakes in the bushes. But if you swam or washed up on the island unarmed, you'll have to improvise by picking up any available trash you can find on the beach, or see if the island's plants can help you out. If the island happens to have palm trees or bamboo forests, you're in luck. You can build a simple hut using bamboo as rafters and palm fronds as a roof and walls. Remember not to sleep directly on the ground, it's best to use the leaves as a bedding to prevent the ground from getting too damp.
Next it's time to find water. Check to see if there's a river or lake nearby, or if there's a deep pit full of rainwater. Don't be afraid if you can't find a source of water. Morning dew is like syrup, and a shower of rain is sweet rain. Sea water, urine and even animal blood are not the best thirst quenchers, so don't try them unless you have to. At the same time, you should minimize your activity level to prevent excessive sweating and water loss.
After a long day's work, you'll be hungry. Finding food is inevitable, but don't forget one important thing first: fire! The importance of fire in wilderness survival goes without saying, but let's emphasize it again. Fire can:
Dry wet clothes
Cook food
Provide warmth and security
Signal the need for rescue by sending out a smoke signal
Scare away wild animals
Smoke out unwanted insects
Start gathering wood while the night is still young. Gather wood; you'll need flammable ignition primers, as well as twigs and logs for sustained burning. It's best to have something dry and small to ignite, like those barks and fibers. If you have matches or a lighter, that's great, but if not, you'll have to try your hand at primitive wood burning. Once the fire is lit, don't let it go out. In addition, you can make a pyrotechnic signal by building a large fire with lots of dry shrubs and leaves, covering it with green leaves, without starting a flame, but just keeping it full of smoke, and lighting it as soon as you spot an airplane or ship passing by.
As far as food is concerned, the ocean is a huge reservoir of resources, in addition to the wild fruits and prey found on the islands. But beware of food poisoning, as we know from experience that "ugly fish are bad," and there are some fish that are best avoided, such as jellyfish, fish with sharp spines, parrot-like beaks, and balloon-like swellings. If you don't have ready-made fishing gear on hand, why not try your hand at making a traditional harpoon? Split the end of a long piece of bamboo into four cross-shaped forks, tie them with thread to separate and secure them, and then sharpen the tips of the forks. Whether or not you can successfully spear a fish depends on your personal skill and proficiency.
Also, turtles are easy to find on the beach, which can be a great meal for the down-and-out. Turtle blood is a nutrient-rich, salt-free, high-quality beverage. Turtle meat is tasty and very filling, and turtle fat is also a great source of goodness. If you're lucky, you'll be able to feast on turtle eggs. But beware of the turtle's biting mouth and sharp claws. Otherwise, the conch that clings to the rocky shoreline and the shellfish in the shallow waters are also good enough to satisfy your hunger.
At this point, the only thing you have to do is wait for help. The hardest part of living on an island isn't shelter, food or water, because with a little ingenuity and hard work, you'll overcome them all. The hardest part is to stay optimistic and hopeful, especially if you are alone. So, no matter what, don't lose faith. Believe that you will be saved and you will be able to reach this moment.
