How to be in the desert; Survival in the park?

[tr] Common sense of desert exploration [/tr] April, 2007.13 Source: To travel in desert areas for simple life, EzLife should first learn as much as possible about relevant information, including the journey, distinctive landforms, climate change characteristics, animals and plants, etc. Especially the information about water sources: where there are oases, wells and puddles, and seasonal rivers during the journey. Be sure to make a detailed action plan in advance based on this information. What should I do if I am in distress in the desert for other reasons such as vehicle failure or disorientation? What are the chances of water living in the desert? The most important thing is whether you can replenish water and protect yourself from the sun. If you are far from a known water source, how can you find water? First, you can dig at the lowest point of the dry river bed and the lowest point of the sand dunes, and you may find groundwater. Second, the roots of desert plants contain some water, which can be dug out and juiced for drinking. 3. Due to the large temperature difference between day and night in desert areas, fresh water can be obtained by condensation. The specific method is to dig a pit with a diameter of about 90 cm and a depth of 45 cm on the ground. The air and soil in the pit heat up rapidly, producing steam. When the water vapor reaches saturation, it will condense into water droplets inside the plastic sheet and drip into the container below, so that we can get precious water. In this way, in desert areas with large temperature difference between day and night, at least 500 ml of water can be obtained one day and night. This method can also be used to distill and filter dirty water that cannot be directly drunk. Fourth, you can also look for water according to the plants and animals in the desert. Most animals should drink water regularly. Herbivores don't stay away from water. They usually go to a fixed place to drink water in the morning and evening. Generally, they can find water as long as they find the paths they often pass and look for lower places. Carnivores can get water from their prey, so they can't drink water for a long time, so there may be no water in this carnivorous area. Carnivorous birds such as eagles and waterfowl can go without water for a long time. So seeing them doesn't necessarily mean that there is water around them. In desert and arid areas, when you see reptiles, you can't say that there is water around. Because they are likely to suck dew or get water from their prey, they can not drink water for a long time. Finding insects is a good sign of water source. Bees, in particular, can't leave the hive more than 6.5 kilometers, but there is no fixed activity time. Most kinds of flies will not leave the water source more than 100 meters. If you find flies, it means there is water near you. How can we keep the water in the body from losing? According to the known experimental results, we know that in the case of water shortage, if people have been resting in a place that can block the sun. 48 degrees can last for two and a half days, and 2 1 degree can survive 12 days. If you are forced to go to a safe place, how far you can go depends entirely on how much water there is. If there is no water, when the temperature is 48 degrees during the day, rest during the day and March at night, you can walk 40 kilometers. If you must bask in the sun during the day, it will not exceed 8 kilometers. Under the same conditions, if you have 2 liters of water, you can walk 56 kilometers for 3 days. If there are more than 4.5 liters of water every day, the chances of survival will be greatly increased. ● In order to prevent the loss of water in the body, we should try our best to do the following: ● Take more rest and use less force. ● Don't smoke. ● Try to stay in the shade and avoid direct sunlight. If you can't find it, you can do something to prevent the sun. ● Don't lie directly on the hot ground. ● Try not to eat or eat less. Because in the case of water shortage, the body will absorb water from various organs and tissues to digest food. ● Never drink alcohol. Alcohol must also absorb water from various organs of the body before it can be broken down. ● Don't breathe through your mouth. Breathe through your nose and don't talk too much. When there is no water to drink for a long time and it is hard to find water, don't try your best to swallow it all at once. People who are about to dehydrate will vomit and lose more water in their bodies if they drink water violently. Never take off your clothes when you are in distress in the desert. Clothes can not only prevent your skin from being burned by strong sunlight, but also effectively keep your body from losing water. It is best to wear loose clothes to keep a layer of insulated air between your body and your skin. Cover your head and feet carefully. If you cover the distress in the desert during the day, you should first take measures to find a place where the sun can't shine directly. You can use the shadow provided by the protruding part of the rock and the rock wall of the main ditch to lie down and rest quickly, and then find a way after dark. Fire, fire and smoke in the desert are all eye-catching signals, which can be used for cooking or heating at night. In desert or arid areas, shrubs and weeds are very dry and flammable, which can be used as fuel, and the feces of animals such as camels can also be used as fuel. If you can't find natural fuel, you can put sand in a container, mix some gasoline and engine oil, and it will burn for a long time after ignition. The food is in the desert, and the hot weather will definitely affect the appetite. Don't eat reluctantly. High-protein food will increase the body's calories and accelerate the loss of water in the body. Digesting any food will consume water in the body. If there is water shortage, it is best not to eat food or only to eat water-containing foods such as fruits and vegetables. One thing, in desert areas, food is perishable, so any food should be eaten as soon as possible. Never eat bad food, so as not to affect your health. Health ● In the desert, extreme dryness or exposure can cause many diseases ● Continuous sweating can lead to a large loss of salt in the body and cause cramps. ● Sweating and the friction of clothes will lead to the blockage of sweat glands and make the body grow prickly heat. ● Spasm caused by overheating will cause heat exhaustion. ● Constipation and dysuria are also common. As long as you always cover your head, body, hands and feet, rest in the shade during the day and come out after sunset, you can effectively avoid these diseases. References:
