Common misunderstandings for outdoor survival

Myth 1: You can suck out the venom after being bitten by a snake

Fact: If a snake leaves venom in your body after biting you, it will immediately enter the blood. Putting your mouth on the bite will bring extra bacteria to the wound, and it may also suck venom into your mouth and esophagus. If someone is bitten, please try to keep a low heart rate and keep the affected limb below the heart position on the way to the doctor.

Myth 2: Always play dead when attacked by a bear

Fact: If you see a bear in the forest, the usual advice is to leave as soon as possible. If the bear is in your yard or around your campsite, please try to make yourself look tall and shout, which may scare it away. But if you are really attacked by a bear, your reaction should depend on the bear and the type of attack. It's useless to play dead when a black bear attacks, but it's useful to fight back.

In most cases, brown bears or grizzly bears attack you to protect themselves or their children. In these cases, it will scare you away by making noise or pretending to attack. At this time, you can slowly retreat from this defensive attack. If the bear touches you, you can lie prone with your neck under your hand. But if it is a predatory attack without warning, then please fight for your life.

Myth 3: If you get lost in the wild, you should look for food at once

Fact: it doesn't need to be so fast. You can live for six weeks without food. The extra time may change, depending on your initial state and other health problems, but water and shelter are more important than food.

Myth 4: The liquid in the cactus can quench your thirst

Fact: If you have the experience to pick out the barrel cactus that allows you to safely filter out the water, then there is no problem with this statement. But in most cases, the liquid in cactus will make you sick, make you spit out precious liquid, and make you more dehydrated.

Myth 5: There is more moss on the north side of the tree

Fact: Moss can cover all directions of the tree, depending on environmental conditions. Don't try to navigate with this folk custom. Common tips for outdoor survival 2

How to make a fire outdoors

Friends who often go outdoors may have had the experience of making a fire outdoors. In a harsh outdoor environment, if necessary, they can build a fire, which can not only drive away the cold, give people warmth, but also enhance people's self-confidence. The raw fire can also be used for cooking food, which is very useful. So how to make a fire outdoors?

1. Use a convex lens

After the intense sunlight is focused by the convex lens, it can generate enough heat to ignite the fire. Among them, the fastest way to get fire is to irradiate gasoline and alcohol, which can ignite the fire within 1-2 seconds. Magnifier or telescope and convex lens in camera can serve you instead of convex lens. In addition, setting fire to the focus of the flashlight reflective bowl can also make fire towards the sun. If there is ice and snow, it is also possible to process the ice into a shape with thick middle and thin periphery instead of convex lens.

2. Strike a stone to make a fire

As we all know, our ancestors used flint to make a fire. In fact, when I go outdoors now, we can also find a hard stone to make flint, and knock it down with the back of a knife or a small piece of steel to make the spark fall on the big fire. A hacksaw with teeth on the edge can produce more sparks than an ordinary knife. When the fire begins to smoke, blow or fan it slowly to make it ignite an open flame. Of course, not any stone can ignite the fire, and the spark struck by the stone must have a certain amount of heat and duration to ignite the fire. Drawing on the same idea, now, donkey friends prefer to make a fire with magnesium rods; Moreover, magnesium rods are easy to ignite and carry.

3, battery fire

If there is a battery with a large amount of electricity, connect the positive and negative poles at both ends of the peeled pencil lead, and in an instant, the pencil lead will burn as red as electric furnace wire. If you travel by car, you can take two long wires and connect them to the positive and negative terminals of the battery. If there is no wire, you can use two wrenches or other metal tools instead. If the lead is not long enough, the battery can be taken out of the car. Touch the ends of two wires slowly, and short circuit will produce sparks. At this time, a piece of cloth dipped in gasoline is the best kindling.

4. Drilling wood for fire

Using the most primitive and traditional ways to drill wood for fire and bow wood for fire are the most difficult and primitive ways to use natural materials for fire. Tie shoelaces, ropes or belts with tough branches or bamboo pieces to make a bow. Wrap a dry stick around the bow and use it to spin quickly on a small piece of hardwood. This will drill out black powder, and finally, these powders will smoke and produce sparks to ignite the fire.

Method of building a fire

1. Cross type

Overlap some smaller round logs layer by layer at a proper angle, so that a fire will project a lot of heat, and this structural foundation is relatively solid and will not collapse easily. At the same time, such a structure can also form deeper ashes or embers, which is perfect for cooking food. Preferred method for outdoor fire.

2. Star-shaped

Thick round wood can be slowly added to the central area to make it star-shaped. This method can avoid the possible problems caused by the burning of some oversized wood, and also provide a stable cooking platform for the cooker.

3. Conical tent type

This shape is similar to the conical tent of Indians. The flame can burn upwards in the middle hole, just like a well-ventilated chimney in the home, which can continuously draw fire and smoke upwards. Using this structure can provide a greater degree of lighting, but the shortcomings are also obvious, the fire burns quickly, and it is not stable enough to collapse easily.

4. Trench type

This type is suitable for windy outdoor. Before building this structure, it is necessary to dig a trench with a depth of 3cm, a width of 3cm and a length of 1m on the ground, and pile it with stones at the edge of the trench. You can also bury it after using the fire as an excellent source of geothermal energy. However, be careful with wet rocks with pores, because they may explode when heated, which will not pay off.

5. Snake Cave

You can dig a hole in the downwind of the river bed and pile branches or other things to form a hole above it, which is equivalent to making a chimney. Making a fire underground can provide a focused heat source, which can be used to cook food and preserve fuel. In addition, in this way, the fire can absorb a lot of air from the gap, reduce the amount of smoke, and can be ignited in a windy place.

Precautions for outdoor fire

1. Site selection must be paid attention to. After the camp is selected and the tourist tent is set up, some dry wood (such as dead wood, dead branches and leaves, hay, etc.) should be collected for ignition, and then a pit-shaped kitchen bottom with moderate depth should be dug in the field (such as building the kitchen bottom with stones in rainy days), so as to prevent the strong wind from blowing out or blowing off the fire, and at the same time, it can be used up.

2. Spread a layer of logs on the bottom of the stove, build a cone-shaped firewood pile, then put in kindling and fill it with igniters to light the bonfire, and then add firewood appropriately to maintain the fire; If you need to light a bonfire overnight, it's best to arrange personnel to take shifts to avoid unexpected accidents.

3. Put out the used bonfire completely, then cool the ashes and put them in the into the pit and fill them with soil. Make sure that the ashes are completely extinguished.
