How to prevent frostbite in winter



When the skin is exposed to severe cold temperatures of minus 2 to 10 degrees Celsius, soft tissue freezes and blood supply to the area is lost, it is commonly called frostbite.

It is a disease that usually occurs in the middle of winter. Occurs frequently between dawn and morning when the temperature drops sharply.

 

1. Cause

 Blood circulation in the skin is the most important factor in body temperature abandonment. Working outside in cold weather makes it difficult to maintain central body temperature. If placed in an environment exposed to the cold for a long time, vascular contraction will continue, resulting in a decrease in blood flow to the end of the body.

  There are few cases of frostbite in daily life, but they are exposed to cold conditions for a long time, or are involved in the occurrence of humidity, gout, and the medical conditions of the atmospheric body. Climbing, polar exploration, and prolonged exposure can lead to younger siblings.

 

2. Symptoms

 Symptoms of frostbite occur depending on the degree of exposure to the outside for a long time in cold winter weather. The most common symptom is sensory impairment of the damaged area and more than 75% of patients complain. The frostbite area can be cold and pale, sensory deterioration or numbness, swelling of the skin, and blisters.

 

3. First aid

 First, you have to warm the patient's body. Remove wet clothing and cover the entire body with a warm blanket. It is better to raise the body temperature gradually than to raise the temperature suddenly. It is recommended to soak in warm water of 37-39 정도의 for 20 to 40 minutes.

 

4. Precautions

● There is a risk of burns by immersing the frostbite area in hot water above 40 over.

● Blisters do not explode.

● Do not rub or massage frostbite areas (wiping can destroy the cells)

● Never give alcohol to a patient (alcohol can cause the body's heat to be released by blood vessel expansion, resulting in hypothermia).

● Climbing the frostbite area close to the fire, electric blankets, hot water kettle stoves, etc. may cause additional tissue damage due to excessive heat.

 

5. Prevention

 Above all, the body should be protected from exposure to severe cold. If it is inevitable, it should be kept warm with clothes, socks, etc. You have to change your wet socks and so on. It is important to keep your whole body warm as well as the extremities such as fingers, toes, and ears.   After treatment, care must be taken to protect the frostbite area so that it does not get hurt. You should also avoid standing for a long time and avoid alcohol and smoking thoroughly.
