Frostbite ( frostbite ) - damage to tissues and organs due to exposure to low temperatures of 5-10 degrees and below. Recall that burns occur at a temperature of 60 degrees and above.

Frostbite is always accompanied by a general undercooling of the body, but it also happens that the body's hypothermia can occur and without frostbite of tissues and organs due to the effect of temperature not lower than 0 degrees, with loss of consciousness in the open cool air, getting into cold water a person may die.
Reasons for frostbite
The reasons for frostbite can be: high humidity, tight or wet shoes, immobile position of the victim and so on. To promote hypothermia and frostbite, factors such as alcohol intoxication, wind, blood loss, reduced body resistance and exhaustion can contribute.
Signs and symptoms
The most commonly exposed areas of the body are frostbitten with low blood supply: ears, nose, limbs, fingers and toes. The patient first feels a feeling of cold, tingling. Then comes numbness and the sensitivity of the affected area is completely lost.
Under the influence of low temperature during frostbite, inflammation of the tissues develops with subsequent necrosis.
In the initial, latent period of cold exposure there is a feeling of tingling, cold, burning, loss of sensation. Then all the phenomena intensify, the sensitivity is lost finally, the limb becomes "like a stranger."After warming in the development of the disease, several periods are noted( after 5-7 days).
Degree of frostbite
- 1st degree - signs of inflammation and necrosis;
- 2nd degree - bubbles are formed, filled with liquid contents;
- 3rd degree - granulation forms on the bottom of the bubbles( growing new tissue);
- 4-th degree - there is moist gangrene and necrosis of damaged tissues.
At the first and second degree, the changes occurring in the tissues are reversible, at the third and fourth degree they are irreversible.
First aid for frostbite and hypothermia
When rendering first aid, the injured person should be transferred to a warm room, covered with blankets, and warmed with warm water bottles.

The victim is given a hot drink, tetanus antiserum is administered, and in case of severe lesions - antibiotics of a wide spectrum of action.
Then, within 5-7 days, the degree of frostbite is determined. Treatment frostbite depends on the degree of tissue damage.
Bubbles arising from frostbites should be removed if they are large or contaminated. They are also punctured and pruned at the base. It is best not to remove the blisters within 6-7 days. Usually by this time they are damaged and removed with the next dressing.
When frostbitten face treatment should be carried out in an open manner( without dressings), to achieve the rapid drying of dead tissue and healing them under the scab.

Survival in the taiga: hypothermia and frostbite in the frost -55
In the taiga in the frost, one must be very careful, if there is no practice, it will easily frostbite. It is advisable to read the work of Jack Londan Koster before the release, otherwise it will turn out like in this video.
Nothing boded ills, in the taiga in the frost -50 everything seemed to be in order, and already in the hut I felt that with my fingers on my leg, something is not right. There was a huge swelling on my leg after 2 hours as I went into the hut. The tumor over time was very sore and was becoming increasingly tearing near lying tissue of healthy skin.
I had to remove a large area of skin on the tumor to stop it. Frostbite of the second degree. And if the cooling comes to the bone, then perhaps Gangrene, blood infection and amputation of the limb, and even life. Be very careful in frost. It is better to wait in the hut or at home.
