When the skin comes into contact with very cold air or objects, causing vasospasm, congestion, and swelling, it is called frostbite. Severe frostbite may cause blisters and even ulceration. Additionally, touching the freezer compartment of the refrigerator can also cause frostbite.
Frostbite throughout the body is very dangerous, and multiple precautions should be taken. When suffering from frostbite, almost all patients will experience dizziness and drowsiness. If the patient is allowed to sleep, their body temperature will gradually decrease and they will freeze to death.
First aid measures
The key to first aid for local frostbite is to slowly soak the affected area in warm water that is the same as body temperature to raise the temperature. If it’s just a frostbite, you can place your hand under your armpit to warm up. Then wrap the affected area with clean gauze and go to the hospital for treatment.
2. Frostbite throughout the body can be dangerous if the body temperature drops below 20 ℃. It is important not to go to sleep at this time, as it is important to keep your spirits up and stay active.
3. When a person with systemic frostbite experiences slow pulse and breathing, it is necessary to ensure unobstructed respiratory tract and perform artificial respiration and heart massage. To gradually restore body temperature, then quickly go to the hospital.
Precautions
The purpose of first aid for local freezing is to restore normal body fluids. Therefore, if the affected area can be warmed up, it can be cured quickly. Do not soak the affected area directly in hot water or grill it with fire, as this can worsen frostbite. Since massage can cause infections, it is best not to massage.
2. Boil eggplant or chili straw in water, wash areas prone to frostbite, or apply ginger to local skin to prevent freezing.
