What is freezing?

Frostbite refers to the freezing of body tissues (usually the skin) that occurs when blood vessels constrict, reducing blood flow and oxygen to the affected area of ​​the body.

 Normal sensory loss and color change in these tissues.

 Frostbite is far from the center of the body and is more likely to affect parts of the body where blood flow is low. This includes feet, toes, hands, fingers, nose, and ears. three types are freezing

 of freezing: freezing, superficial freeze, ing, and deep freezing. Children, the elderly, and people with cardiovascular problems are at high risk of frostbite, but it mostly occurs in adults between the ages of 30 and 49, as the affected area can become paralyzed. With emergency medical care, most people recover completely from frostbite. However, in severe frostbite, permanent damage can occur depending on the time and depth at which the tissue is frozen. In severe cases, blood flow to the area may stop, causing permanent damage to blood vessels, muscles, nerves, tendons, and bones. If the frozen tissue dies, it may be necessary to amputate the affected area.

 What causes frostbite?

Frostbite is usually caused by prolonged exposure to low temperatures, especially with a low air cooling factor. It can also occur after brief exposure to very low temperatures.

 What are the symptoms of frostbite?

For the ice:

•  White patches on numb skin. In case of freezing (surface or deep):
•  The skin is white or grayish-yellow, rough, waxy, numb or blistered, darkened or blackened. Other symptoms are swelling, itching, burning sensation, and deep pain during the rewarming/healing process. How is frostbite diagnosed? Frostbite is first diagnosed based on symptoms and physical examination.
•  Three to five days after rewarming, doctors use imaging tests to determine how much tissue has been damaged.
•  After 1-3 weeks, the images will help locate damaged blood vessels and identify areas that may require amputation.

 What is the treatment for the common cold?

Most people recover completely from frostbite, but the affected area is susceptible to cold and sun damage and is more likely to frostbite again. The first goal of treatment is to rewarm the affected area.

 Frost Nip can be treated at home. If you suspect you have

 Don nip, get out of the cold ASAP. If wet, change to dry clothes. Soak the affected area in warm water (100-105 F) to thaw the frozen tissue. Do not use hot water as it may cause burns. If hot water is not available, use your body temperature by placing your hands under your armpits or covering your nose, ear,s, and face with dry hands.

Note: Do not rub the affected area. It can damage tissue. Do not use hot compresses, heat lamps, stoves, fireplaces, or radiators to rewarm the affected area. These methods can heat the skin unevenly or cause burns, especially if the skin is numb and you don't know how hot it is.
