There are countless different hazards and challenges we can run across whenever we are in a survival situation, but you can break down the necessities of life and survival in the wilderness into a few critical elements. In this post we lay out what your top priorities should be in a survival situation. We organized them by threat level, basically what can kill you first and worked our way down.

Shelter
Protect yourself from danger, weather and temperature. 
Keep body core temperature. Hypothermia and heat stroke can kill you within minutes
Picture
Whether you’re in the woods or in the desert, you need protection from the elements and security from danger. A well constructed shelter can provide protection and security. It will protect you from the elements and the havoc they can wreak on one’s body. A shelter will also provide a place for you to sleep as restfully as possible, given your situation. A shelter can be a portable tent you have with you, or it can be as simple as using a plastic tarp to help you set up a lean-to. When you find a likely area, you will need to scout out the immediate vicinity. See our section on shelter building

Fire

Critical elements/gear in hot temperatures
Shade
- cover, tarp etc
Hydration. Which brings us to our next subject



Water
After keeping you body temperature, keeping yourself hydrated is your next priority. Dehydration can kill you in a matter of a coupe of days. 

Picture
In ordinary conditions, we need two to three liters of water per day. If challenged, we can actually survive without water for about three days. Conserving your water doesn't just mean that you need to be careful how much you are drinking; it also means watching how much you need to physically exert yourself. The less you move about, the less water you will need. In very hot climates, it won’t take much to over exert yourself: do that and you run the risk of dehydration. See our section on water sourcing

Once you find water, you will need to make sure it is drinkable. There could be unseen pollutants or pathogens, so you do need to be careful. Even if it’s from a mountain stream, there are usually bacteria or other microorganisms present in any natural water supply; filtering the water through charcoal will remove any dirt or debris, but you need to make sure you kill those microscopic pests by boiling any water you intend on drinking.



Fire
Uses: Heat, water purification & cooking


Next to water, or perhaps equal to in importance, finding the way to make a fire is at the top of your survival “to do” list. You need a fire to help you boil water to make it safe to drink; to cook any food, especially any wild fish, animals or eggs you manage to snare; to help you stay warm, especially when the temperature drops at night; to keep dangerous animals away; to provide you with a sense of security and last but not least, to visibly signal any possible search and rescue teams as to your location. 
Picture
The best and easiest way to ensure you can build a fire is to make sure you packed some matches, or better yet, a lighter, in a waterproof container. If you didn't, don’t panic; they may not be as quick or easy, but there are other ways to light a fire.

Building a fire is a gradual process that you cannot skip steps on. If you don’t have enough of a flame or ember base before you add the larger pieces of wood, the only thing you will succeed in doing is killing your fire before it even gets started. Make sure that you have enough wood stockpiled each day so you can keep your fire going all night long, and keep checking the fire to make sure it does not go out on you: you worked too hard to start it to begin with! Check out our post 101 Ways to Start a Fire

Food
Once your water sources have been secure its time to work on finding food.

Picture
Food is an important need, but not your most pressing matter in the event of a disaster. You can actually survive for several weeks without it. Long before you are in danger of dying from starvation, you will start noticing these symptoms, so you will still have time to find food:
· Weakness
· Irritability and low morale
· Confusion, disorientation and poor judgment
· Weakened immune system
· Inability or difficulty in maintaining normal body temperature

As long as you know where to look, and what to look for, it’s fairly easy to find food no matter where you are. If you make sure you have a basic knowledge of hunting, fishing and trapping animals, you should do fine. Check out our section food procurement here

You should also know what plants (lichens or fungi) you can and cannot eat. A good basic edibility test before you try to eat something that may be unfamiliar, is to make a minor fingernail scratch on your skin and then rub the plant over that area.

Once you've ascertained what you can eat, do your best to eat as balanced a diet as possible, especially if you are going to need to survive for a long period of time.

Communication
If you establish continuous shelter, water, fire and food sources, you should technically be able to survive for a while, but getting rescued can greatly improve your chances of survival,

Picture
If you are stranded in a backcountry setting and you need to be rescued, effective communication can be one of your most important resources. Know the distress and rescue communications conventions, and plan quickly to communicate your distress signal so that you can attract the attention you need before it’s too late.

Common useful communication equipment includes:
Ham Radio
Whistle
Signalling mirrors
Flashlights

See the following post 10 tips for getting rescued, Signaling and Communication in the wilderness

In a survival situation it may be very necessary to operate below the radar, and keep a very low profile to avoid detection. If your communication efforts are focused on communicating with team or family members you may want to choose a communication system that is silent or at least stealthy. Communications can be as sophisticated as a radio systems, or something as simple as a flashlight or signaling mirrors.

There has to be a level of coordination and communication setup before and disaster or survival situation arises, this is something you want learn before you need to actually use it.

Cold Weather Injury Prevention and Treatment

When you are healthy, your inner core temperature (torso temperature) remains almost constant at 37 degrees C (98.6 degrees F). Since your limbs and head have less protective body tissue than your torso, their temperatures vary and may not reach core temperature.

Your body has a control system that lets it react to temperature extremes to maintain a temperature balance. There are three main factors that affect this temperature balance-heat production, heat loss, and evaporation. The difference between the body's core temperature and the environment's temperature governs the heat production rate. Your body can get rid of heat better than it can produce it. Sweating helps to control the heat balance. Maximum sweating will get rid of heat about as fast as maximum exertion produces it.

Shivering causes the body to produce heat. It also causes fatigue that, in turn, leads to a drop in body temperature. Air movement around your body affects heat loss. It has been calculated that a naked man exposed to still air at or about 0 degrees C can maintain a heat balance if he shivers as hard as he can. However, he can't shiver forever.

It has also been calculated that a man at rest wearing the maximum arctic clothing in a cold environment can keep his internal heat balance during temperatures well below freezing. To withstand really cold conditions for any length of time, however, he will have to become active or shiver.

COLD TEMPERATURE INJURIES
The best way to deal with injuries and sicknesses is to take measures to prevent them from happening in the first place. Treat any injury or sickness that occurs as soon as possible to prevent it from worsening. The knowledge of signs and symptoms and the use of the buddy system are critical in maintaining health. Following are cold injuries that can occur.

Hypothermia
Hypothermia is the lowering of the body temperature at a rate faster than the body can produce heat. Causes of hypothermia may be general exposure or the sudden wetting of the body by falling into a lake or spraying with fuel or other liquids.

The initial symptom is shivering. This shivering may progress to the point that it is uncontrollable and interferes with an individual's ability to care for himself. This begins when the body's core (rectal) temperature falls to about 35.5 degrees C (96 degrees F). When the core temperature reaches 35 to 32 degrees C (95 to 90 degrees F), sluggish thinking, irrational reasoning, and a false feeling of warmth may occur. Core temperatures of 32 to 30 degrees C (90 to 86 degrees F) and below result in muscle rigidity, unconsciousness, and barely detectable signs of life. If the victim's core temperature falls below 25 degrees C (77 degrees F), death is almost certain.

To treat hypothermia, rewarm the entire body. If there are means available, rewarm the person by first immersing the trunk area only in warm water of 37.7 to 43.3 degrees C (100 to 110 degrees F).

CAUTION - Rewarming the total body in a warm water bath should be done only in a hospital environment because of the increased risk of cardiac arrest and rewarming shock.

One of the quickest ways to get heat to the inner core is to give warm water enemas. Such an action, however, may not be possible in a survival situation. Another method is to wrap the victim in a warmed sleeping bag with another person who is already warm; both should be naked.

CAUTION - The individual placed in the sleeping bag with victim could also become a hypothermia victim if left in the bag too long.
If the person is conscious, give him hot, sweetened fluids. One of the best sources of calories is honey or dextrose; if unavailable, use sugar, cocoa, or a similar soluble sweetener.

CAUTION - Do not force an unconscious person to drink.

There are two dangers in treating hypothermia--rewarming too rapidly and "after drop." Rewarming too rapidly can cause the victim to have circulatory problems, resulting in heart failure. After drop is the sharp body core temperature drop that occurs when taking the victim from the warm water. Its probable muse is the return of previously stagnant limb blood to the core (inner torso) area as re-circulation occurs. Concentrating on warming the core area and stimulating peripheral circulation will lessen the effects of after drop. Immersing the torso in a warm bath, if possible, is the best treatment.

Frostbite
This injury is the result of frozen tissues. Light frostbite involves only the skin that takes on a dull whitish pallor. Deep frostbite extends to a depth below the skin. The tissues become solid and immovable. Your feet, hands, and exposed facial areas are particularly vulnerable to frostbite.

The best frostbite prevention, when you are with others, is to use the buddy system. Check your buddy's face often and make sure that he checks yours. If you are alone, periodically cover your nose and lower part of your face with your mitten-ed hand.

The following pointers will aid you in keeping warm and preventing frostbite when it is extremely cold or when you have less than adequate clothing:

•  Face. Maintain circulation by twitching and wrinkling the skin on your face making faces. Warm with your hands. 

•  Ears. Wiggle and move your ears. Warm with your hands. 
•  Hands. Move your hands inside your gloves. Warm by placing your hands close to your body. 
•  Feet. Move your feet and wiggle your toes inside your boots.

A loss of feeling in your hands and feet is a sign of frostbite. If you have lost feeling for only a short time, the frostbite is probably light. Otherwise, assume the frostbite is deep. To rewarm a light frostbite, use your hands or mittens to warm your face and ears. Place your hands under your armpits. Place your feet next to your buddy's stomach. A deep frostbite injury, if thawed and refrozen, will cause more damage than a non-medically trained person can handle. The table below lists some do's and don'ts regarding frostbite. 


Picture


Trench Foot and Immersion Foot
These conditions result from many hours or days of exposure to wet or damp conditions at a temperature just above freezing. The symptoms are a sensation of pins and needles, tingling, numbness, and then pain. The skin will initially appear wet, soggy, white, and shriveled. As it progresses and damage appears, the skin will take on a red and then a bluish or black discoloration. The feet become cold, swollen, and have a waxy appearance. Walking becomes difficult and the feet feel heavy and numb. The nerves and muscles sustain the main damage, but gangrene can occur. In extreme cases, the flesh dies and it may become necessary to have the foot or leg amputated. The best prevention is to keep your feet dry. Carry extra socks with you in a waterproof packet. You can dry wet socks against your torso (back or chest). Wash your feet and put on dry socks daily.

Dehydration
When bundled up in many layers of clothing during cold weather, you may be unaware that you are losing body moisture. Your heavy clothing absorbs the moisture that evaporates in the air. You must drink water to replace this loss of fluid. Your need for water is as great in a cold environment as it is in a warm environment. One way to tell if you are becoming dehydrated is to check the color of your urine on snow. If your urine makes the snow dark yellow, you are becoming dehydrated and need to replace body fluids. If it makes the snow light yellow to no color, your body fluids have a more normal balance.

Cold Diuresis
Exposure to cold increases urine output. It also decreases body fluids that you must replace.

Sunburn
Exposed skin can become sunburned even when the air temperature is below freezing. The sun's rays reflect at all angles from snow, ice, and water, hitting sensitive areas of skin--lips, nostrils, and eyelids. Exposure to the sun results in sunburn more quickly at high altitudes than at low altitudes. Apply sunburn cream or lip salve to your face when in the sun.

Snow Blindness
The reflection of the sun's ultraviolet rays off a snow-covered area causes this condition. The symptoms of snow blindness are a sensation of grit in the eyes, pain in and over the eyes that increases with eyeball movement, red and teary eyes, and a headache that intensifies with continued exposure to light. Prolonged exposure to these rays can result in permanent eye damage. To treat snow blindness, bandage your eyes until the symptoms disappear.

You can prevent snow blindness by wearing sunglasses. If you don't have sunglasses, improvise. Cut slits in a piece of cardboard, thin wood, tree bark, or other available material. Putting soot under your eyes will help reduce shine and glare.

Picture
Constipation
It is very important to relieve yourself when needed. Do not delay because of the cold condition. Delaying relieving yourself because of the cold, eating dehydrated foods, drinking too little liquid, and irregular eating habits can cause you to become constipated. Although not disabling, constipation can cause some discomfort. Increase your fluid intake to at least 2 liters above your nor

Cold Weather Survival Basics

One of the most difficult survival situations is a cold weather scenario. Remember, cold weather is an adversary that can be as dangerous as an enemy soldier. Every time you venture into the cold, you are pitting yourself against the elements. With a little knowledge of the environment, proper plans, and appropriate equipment, you can overcome the elements. As you remove one or more of these factors, survival becomes increasingly difficult. Remember, winter weather is highly variable. Prepare yourself to adapt to blizzard conditions even during sunny and clear weather. 

This post is meant to address a few basics when dealing with cold weather, we will go more in depth in the medical aspects and potential cold related injuries and conditions in our post Cold Weather Injury Prevention and Treatment.


Cold is a far greater threat to survival than it appears. It decreases your ability to think and weakens your will to do anything except to get warm. Cold is an insidious enemy; as it numbs the mind and body, it subdues the will to survive. Cold makes it very easy to forget your ultimate goal, to survive.

COLD REGIONS AND LOCATIONS

Cold regions include arctic and subarctic areas and areas immediately adjoining them. You can classify about 48 percent of the northern hemisphere's total landmass as a cold region due to the influence and extent of air temperatures. Ocean currents affect cold weather and cause large areas normally included in the temperate zone to fall within the cold regions during winter periods. Elevation also has a marked effect on defining cold regions.

Within the cold weather regions, you may face two types of cold weather environments-wet or dry. Knowing in which environment your area of operations falls will affect planning and execution of a cold weather operation.

Wet Cold Weather Environments

Wet cold weather conditions exist when the average temperature in a 24-hour period is 10 degrees C or above. Characteristics of this condition are freezing during the colder night hours and thawing during the day. Even though the temperatures are warmer during this condition, the terrain is usually very sloppy due to slush and mud. You must concentrate on protecting yourself from the wet ground and from freezing rain or wet snow.

Dry Cold Weather Environments

Dry cold weather conditions exist when the average temperature in a 24-hour period remains below -10 degrees C. Even though the temperatures in this condition are much lower than normal, you do not have to contend with the freezing and thawing. In these conditions, you need more layers of inner clothing to protect you from temperatures as low as -60 degrees C. Extremely hazardous conditions exist when wind and low temperature combine.

WINDCHILL

Windchill increases the hazards in cold regions. Windchill is the effect of moving air on exposed flesh. For instance, with a 27.8-kph (15-knot) wind and a temperature of -10 degrees C, the equivalent windchill temperature is -23 degrees C.The table below gives the windchill factors for various temperatures and wind speeds. 


Picture
Remember, even when there is no wind, you will create the equivalent wind by skiing, running, being towed on skis behind a vehicle, working around aircraft that produce wind blasts.

BASIC PRINCIPLES OF COLD WEATHER SURVIVAL

It is more difficult for you to satisfy your basic water, food, and shelter needs in a cold environment than in a warm environment. Even if you have the basic requirements, you must also have adequate protective clothing and the will to survive. The will to survive is as important as the basic needs. There have been incidents when trained and well equipped individuals have not survived cold weather situations because they lacked the will to live. Conversely, this will has sustained individuals less well-trained and equipped.

There are many different items of cold weather equipment and clothing issued by the U.S. Army today. Specialized units may have access to newer, lightweight gear such as polypropylene underwear, GORE-TEX outerwear and boots, and other special equipment. Remember, however, the older gear will keep you warm as long as you apply a few cold weather principles. If the newer types of clothing are available, use them. If not, then your clothing should be entirely wool, with the possible exception of a windbreaker.

You must not only have enough clothing to protect you from the cold, you must also know how to maximize the warmth you get from it. For example, always keep your head covered. You can lose 40 to 45 percent of body heat from an unprotected head and even more from the unprotected neck, wrist, and ankles. These areas of the body are good radiators of heat and have very little insulating fat. The brain is very susceptible to cold and can stand the least amount of cooling. Because there is much blood circulation in the head, most of which is on the surface, you can lose heat quickly if you do not cover your head.

There are four basic principles to follow to keep warm. An easy way to remember these basic principles is to use the word COLD: 
C - Keep clothing clean.
O - Avoid overheating.
L - Wear clothes loose and in layers.
D - Keep clothing dry.


C - Keep clothing clean. This principle is always important for sanitation and comfort. In winter, it is also important from the standpoint of warmth. Clothes matted with dirt and grease lose much of their insulation value. Heat can escape more easily from the body through the clothing's crushed or filled up air pockets.

O - Avoid overheating. When you get too hot, you sweat and your clothing absorbs the moisture. This affects your warmth in two ways: dampness decreases the insulation quality of clothing, and as sweat evaporates, your body cools. Adjust your clothing so that you do not sweat. Do this by partially opening your parka or jacket, by removing an inner layer of clothing, by removing heavy outer mittens, or by throwing back your parka hood or changing to lighter headgear. The head and hands act as efficient heat dissipaters when overheated.

L - Wear your clothing loose and in layers. Wearing tight clothing and footgear restricts blood circulation and invites cold injury. It also decreases the volume of air trapped between the layers, reducing its insulating value. Several layers of lightweight clothing are better than one equally thick layer of clothing, because the layers have dead-air space between them. The dead-air space provides extra insulation. Also, layers of clothing allow you to take off or add clothing layers to prevent excessive sweating or to increase warmth.

D - Keep clothing dry. In cold temperatures, your inner layers of clothing can become wet from sweat and your outer layer, if not water repellent, can become wet from snow and frost melted by body heat. Wear water repellent outer clothing, if available. It will shed most of the water collected from melting snow and frost. Before entering a heated shelter, brush off the snow and frost. Despite the precautions you take, there will be times when you cannot keep from getting wet. At such times, drying your clothing may become a major problem. On the march, hang your damp mittens and socks on your rucksack. Sometimes in freezing temperatures, the wind and sun will dry this clothing. You can also place damp socks or mittens, unfolded, near your body so that your body heat can dry them. In a campsite, hang damp clothing inside the shelter near the top, using drying lines or improvised racks. You may even be able to dry each item by holding it before an open fire. Dry leather items slowly. If no other means are available for drying your boots, put them between your sleeping bag shell and liner. Your body heat will help to dry the leather.

A heavy, down-lined sleeping bag is a valuable piece of survival gear in cold weather. Ensure the down remains dry. If wet, it loses a lot of its insulation value. If you do not have a sleeping bag, you can make one out of parachute cloth or similar material and natural dry material, such as leaves, pine needles, or moss. Place the dry material between two layers of the material.

Other important survival items are survival knives, waterproof matches in a waterproof container, preferably one with a flint attached; a durable compass; map; watch; waterproof ground cloth and cover; flashlight; binoculars; dark glasses; fatty emergency foods; food gathering gear; and signaling items. See our Battle Proven Bugout Bag Here.

Remember, a cold weather environment can be very harsh. Give a good deal of thought to selecting the right equipment for survival in the cold. If unsure of an item you have never used, test it in an "overnight backyard" environment before venturing further. Once you have selected items that are essential for your survival, do not lose them after you enter a cold weather environment.
