Frostbite
Frostbite is damage caused to living tissue, due to extreme cold temperatures.
165 Questions
What types of frostbite can you get?
frostbite means that a part of the body has frozen to the point where blood is no longer flowing, and thus damage has happened to that area (lack of blood is bad). There is only one 'type' of frostbite, and you can get it anywhere, but you can have a mild case, or an extreme case, or anywhere in between. In extreme cases the item usually has to be amputated or gangrene can set in.
How long to get frostbite in -20?
5-10 minutes, depending on conditions. Wind, moisture, and direct exposure may hasten the process.
Serious protective gear is highly recommended if ambient temperatures drop that low (-45C = -49F). Cover all exposed skin (goggles and face mask), use mittens rather than gloves, and make sure to stay dry.
Nobody should go out in that kind of weather unless it's unavoidable.
Frostbite occurs when body tissue or skin is exposed to freezing temperatures. This can happen over a short or prolonged period of time depending on the temperature and wind chill. The nose, ears, fingers, toes, cheeks and chin are often the most susceptible to the freezing cold weather.
Permanent damage to the body can happen which could lead to amputation. People with circulation problems and people who are not dressed appropriately for extreme cold temperatures are most at risk.
Check the victim for symptoms of hypothermia, this could be a medical emergency.
Frostbite Symptoms
Redness or pain in any skin area.
A feeling of pins and needles, followed by numbness.
A white or grayish yellow skin color.
The skin could be hard, pale, cold or have no feeling.
Severe frostbite could appear very white and numb, this could indicate that the tissue has started to freeze. Seek medical attention immediately!
Very severe frostbite can cause blisters, blackened skin or dead tissue (gangrene). Seek medical attention immediately!
Until someone points it out, most victims don't realize they have frostbite due to the numbness and lack of feeling.
Frostbite Treatment
If possible move the victim to a warm place.
The victim should avoid walking if they have frostbitten feet or toes.
Remove any wet clothing or constricting jewelry.
Wrap the affected area with sterile dressing, separating affected fingers and toes and get the victim to medical assistance immediately.
If you can not get immediate medical attention, then the affected area should be immersed in warm (not hot) water. The water temperature should not be more than 104 degrees or should be comfortable to the touch.
If the affected area is ears, nose or cheeks, use warm cloths and apply for 20 to 30 minutes keeping the cloths warm.
If warm water is not available, the affected area can be warmed using body heat. Frostbitten fingers can be heated by placing in the armpit.
During the warming process, severe swelling, burning pain and skin color changes may occur. When the skin is soft and sensation returns, the warming process is completed.
The frostbitten area should not be rubbed using snow or massage. This can cause further damage.
Do not use direct heat from a stove, heating pad, heat lamp, fireplace or other similar heat source. This may increase the chances of burning the victims affected area.
Blisters should not be disturbed.
The victim should not smoke or drink alcoholic beverages. This could interfere with blood circulation.
The frostbitten area should not be thawed out if it can not be kept thawed out. Damage could be worse if the tissue re-freezes.
Frostbite Prevention:
Be aware of factors, such as extreme cold, high winds, wet clothes and poor circulation.
Clothing should be suitable for cold temperatures which would include, mittens (not gloves), water resistant, wind proof, layered clothing. Two pairs of socks (cotton next to skin), hat or scarf that covers the head and ears
Find shelter early if you are caught in a severe snow storm.
To maintain body heat increase physical activity.
When to get professional frostbite treatment:
In the case of severe or very severe frostbite.
If normal color or feeling of the affected does not return.
If symptoms develop such as fever, discoloration or drainage from the affected area.
Start chest compressions:
Put the heel of your hand in the middle of the victim's chest in between the nipples.
Interlock your fingers of your second hand with the first hand and start to compress down on the chest one and a half to two inches (4-5cm).
Let the chest recoil before the next compression.
The chest should be compressed at a rate of 100 per minute.
Continue at that rate until you have completed 30 compressions.

To treat a frostbite you should?
For all kinds of Frostbite 1st degree or 4th degree it should all be treated the same way. To treat frostbite you have to do rapid rewarming in a warm (100 degree to 110 degree) water bath, it is a treatment of choice. Slow rewarming may cause more tissue damage. - A.P
How cold does it have to be to get frostbite?
Cold enough to Freeze and kill the cells so around 0 degrees.
However, if the skin is damp, and especially if there is wind, frostbite can occur at slightly higher temps. This is due to several factors:
1) Moisture evaporating from skin pulls additional heat from the surface. This is why sweating cools you, but it can be a liability in cool conditions.
2) Air movement increases heat loss, both directly (by moving the layer of warmer air next to your skin away more quickly) and indirectly (by increasing the rate of evaporation of any moisture on exposed skin).
3) The human body's built-in reaction to cold conditions (any time core temperature starts to drop) is to constrict blood flow to the extremities to maintain core temperature for as long as possible. Thus, your body's natural reaction may prevent hypothermia, but make you more vulnerable to frostbite.
Put another way:
The ambient temperature does NOT have to be at or below freezing (32F or 0C) for frostbite to occur. If you are wet, the wind is blowing, and you have inadequate clothing, you can still suffer frostbite and/or hypothermia even in temperatures that are technically above freezing.
Even lower ambient temperatures do make it easier to get frostbite, however.
Yes, this happened a great deal on the Russian Front in world war II and related health problem could be hypothermia- death caused by freezing-literally low temperatures. CREEPY
Bites of any kind can make you die. Frost bites are no different. I hope that this helped.
Frost bite comes from skin being exposed to too cold of temperatures, and if too much of the body is exposed, then the blood circulation slows or stops, thereby "killing" the skin, and eventually the body...
Yes, if left untreated the person can die.
Either immediately by extension of the cold (or loss of heat to be precise) until hypothermia does him in.
Or (more likely) because of either gangrene OR there is so much tissue death that the patient becomes toxic from the released potassium.
How long does it take to get frostbite in 0 degrees Fahrenheit?
Frostbite can occur in temperatures around 0 degrees Fahrenheit within 30 minutes to an hour, depending on factors such as wind chill, moisture, and individual susceptibility. Exposed skin, especially extremities like fingers and toes, is particularly vulnerable. Wind can significantly accelerate the onset of frostbite, making it possible to develop it even faster in windy conditions. It's crucial to monitor for signs of frostbite and take precautions in such cold weather.
What is the best first aide fro frostbite?
Gently re-warm the frostbitten extremity in luke-warm water (approx. 94F). As the extremity may be numb, be very careful about using warm and not hot water. Do NOT warm the extremity if there is a change it will re-freeze (e.g. you are still in an exposed position). Also, be advised that, if circulation returns, the results are quite painful. If possible, be prepared to treat for pain. Subsequent blackening of the exposed tissue indicates potential of necrosis, which may require amputation. Note that the idea of rubbing the frostbitten area with snow is purely a wive's tale and invariably will do more harm.
What are the different stages of frostbite?
The three stages are usually called frostnip, superficial frostbite, and deep frostbite. In stage 1 (frostnip), the skin reddens and then turns white. The area may feel numb. In the second stage of frostbite(superficial), the external layer of skin is frozen, but underneath is still soft. The area may appear grayish-yellow. In the final stage of frostbite(deep frostbite) the entire area is solid, and may appear grayish-blue.
What is the difference in frostbite and forstnip?
Frostbite is the destruction of tissue due to exposure to very low temperatures.
If you see the signs of redness, pain, itchiness, hardness, and puffiness and the beginning of it turning black get OUT OF THE COLD AND CONTACT A DOCTOR. There is also a first aid advice kit online. To prevent frostbite though wear a warm coat, gloves, ear muffs, scarf, and a hat, warm shoes. STAY WARM AND DON'T GET COLD.

What are the systoms of frostbite?
Initially, watch out for itching and pain and eventually numbness on the surface of the skin, as well as discolored patches (white, red, or yellow). This is the first stage and typically only affects the surface layers of skin. If patches of skin are frozen hard and waxy, you may be into second or even third degree frostbite.
How does the cold weather effect your body eg frostbite?
Frostbite is freezing of the skin and body tissues just under the skin. It can occur when part of your body is exposed to temperatures or wind chills at or below freezing.
How do you tell if food is frostbitten?
You know you have frost bite if the skin appears pale, hard, and cold to the touch. When you go inside to warm up, your hands will turn red and become very painful.
Which action is most appropriate when caring for someone with frostbitten fingers?
First aid for frost bite is to re-warm the affected skin. Running a frostbit hand under warm (NOT HOT) water is an effective method for warming the skin. The victim should be checked out by a physician promptly because tissue damage can be extensive. In some rare cases, re-warming is not advisable. If you are far from help and your hand is liable to re-freeze, the re-freezing may do more harm than if the skin had remained frozen.
Where on the body is the most common place to get frostbite?
The area most at risk are fingers, toes, ears, and nose. Theses areas receive limited blood flow under normal circumstances. Adding the cold weather that is necessary to do damage, the body shunts blood from peripheral circulation to conserve heat. The tissues dies because a lack of blood flow.
What is the BEST prevention for frostbite?
Stefansson, the famed Arctic explorer, declared that "few things could be more absurd" than the snow cure for frostbite. What you should do, he said, "is to take your warm hand out of your mitten and press it on the frozen spot for a moment until the whiteness and stiffness is gone."
Who is most at risk for frostbite?
inadequate clothing, previous cold injury, fatigue, wound infection, atherosclerosis (an arterial disease), and diabetes. Driving in poor weather can also be dangerous: vehicular failure was a predisposing factor in 15% of the Saskatchewan cases
Why do you never rub someone that has just received frostbite?
If someone has frostbite, which means that their flesh is frozen, the expanded ice crystals inside the cells of the skin, muscle, blood vessels, etc will grate together and break down the cell walls if you rub it.
Think about taking a frozen cut of meat, then rubbing a corner of it. The tissue would begin to break down, you would eventually end up with a pulpy mass.
If you think you have frostbite, get medical attention to save the toe/limb/frozen area.
It is 30 degrees out can you get frostbite?
It takes 18 hrs with a child with medical issues. without medical issues it takes several days being completly exposed
------------------------------------------------
Are you mad?! You're going to lose someone digits with an answer like that!
Frostbite can set in within a matter of a few minutes to a few hours, depending on conditions in addition to the ambient temperature and windspeed, factors such as: degree of exposure, wet vs. dry skin, and the degree of circulation in the area in question. Windchill is of chief concern, as high winds dramatically increase the rate of heat loss from exposed areas.
At any temperature near or below freezing, the human body automatically shunts blood flow away from the extremities to preserve core temperature (and help prevent hypothermia). Fingers, toes, nose, cheeks, and ears are the most at-risk areas.
Those with medical conditions such as diabetes that reduce circulation in the extremities in particular face an increased risk.
Also, tight or restrictive clothing can be problematic. Wearing too many layers of socks inside one's boots, for example, is a common mistake leading to further reduction of bloodflow to feet and toes. The increased insulation is of little value once new heat is no longer flowing from the body's core.
Initial symptoms of first-degree frostbite include itching, pain, and eventual numbness in the exposed area; as well as yellow, white, or red patches of skin.
Caution should be exercised any time temperatures are near or below freezing (32 degrees Fahrenheit or 0 degrees Celsius), particularly in windy and/or damp conditions.
Gingivostomatitis simply means an infection that involves the gums and mouth. Herpes simplex virus (HSV) is the virus that causes both oral and genital herpes. There are two types, HSV-1 and HSV-2. HSV-1 is the primary cause of oral herpes. This virus is acquired quite easily after contact with infected secretions. Up to 70 percent of adults are infected with HSV-1.
Most primary infections with HSV-1 cause no symptoms. However, if a person does have symptoms, the infection can be severe, with fever, swollen glands, sore throat and painful vesicular (blister-like) lesions that quickly rupture, forming ulcers. The lesions can be anywhere. They can involve the tongue, the inside of the cheeks, the lips and the gums. Adults tend to have a particularly severe sore throat. The pain can be intense, and some patients have to be given intravenous fluids because they cannot swallow at all.
Most cold sores are due to the same herpes virus. However, a cold sore represents a recurrent flare-up of illness. This is typically mild, with no fever or malaise (ill feeling). The lesions mostly occur on the lips. The outbreak typically resolves over four or five days, a considerably shorter time than the duration of the primary episode. Since most primary infections are asymptomatic, a recurrence is often the first manifestation of infection.
Your child could have acquired the virus from almost anyone. Contact with the saliva of family members (remember that about 70 percent of us have the virus) could have transmitted the virus. He was just an unlucky person who had a symptomatic infection. There was no way that the infection could have been prevented.

What do you do if you get frost bit?
As soon as possible, get to a safe, warm environment. Make sure the body's core temperature is stable and normal before you begin working on the extremities.
If a warm, stable environment is not readily available, do not begin warming, as re-freezing will do additional damage. Do your best to protect the area from excessive motion and additional freezing and get to a safe environment as soon as possible.
Begin warming the affected area carefully and gently. The idea is to minimize tissue damage, so do not expose it to sources of intense heat or cold, as additional burning or freezing may result (also, reawakening nerves can be hypersensitive).
DO NOT RUB OR MASSAGE the affected area. Ice crystals can form in the tissue, and the motion will cause them to cut and tear, doing additional damage. Minimize movement of the damaged tissue.
Wrap the individual in warmed blankets. This allows gentle, passive warming. It has the added benefit of helping to ensure that core temperature remains stable if hypothermia is a concern (a sudden influx of cold blood from warming extremities as the body's natural constriction of blood flow relaxes can cause clots or shock the heart).
Active warming should be typically be performed by professionals, due to some of the potential complications discussed above. Passive warming should be sufficient for minor, surface frostbite. If any deeper freezing is suspected, medical attention should be obtained as soon as possible. Hard, waxy patches may be a sign of 2nd degree frostbite. Bluish or blackened areas are especially concerning, particularly if an entire digit has changed color.
What temperature does frostbite occur?
Not sure about wind speed, but I do know the temperature at which frostbite sets in.
At negative forty (-40) degrees Fahrenheit, frostbite will begin to set in around your fingers and toes and slowly "creep" towards the center of your body as the temperature steadily falls. Frostbite occurs when the body detects extreme cold. The brain sends a message to blood vessels to "call in the troops" to protect and warm the vital organs. Your brain basically uses your limbs as cannon fodder to keep your heart, lungs, and other vital organs safe from the extremely cold temperatures.
No at negative forty Fahrenheit frostbite will not creep up it will set in fast. It will be within ten min on fingers and toes if you are not dressed properly. With any kind of wind on top of that it will be faster yet. wind plays a very large factor on what the air temperature feels like. For example, at -10F with a 5 mph wind the air temperature feels like -22F.
