Common sense to prevent frostbite in low temperature environments.
This is a kind of severe cold that has never been experienced in the south, and many "southern little potatoes" have gone north to enjoy the snow, have snowball fights, and build snowmen. However, there are also certain dangers that cannot be ignored, such as the appearance of chilblains in winter. A few days ago, burns and wound repair experts from the Affiliated Hospital of the Guangzhou Red Cross Society warned that redness, swelling or soreness on the body is likely to be a precursor to chilblains, and should be evacuated immediately from low-temperature areas and pay attention to keeping warm.
In order to make you better aware of and prevent frostbite, we will educate you about the following preventive measures for frostbite:
1.Limit your time outdoors: On cold, wet or windy days, keep your time outdoors as short as possible. Especially in extremely cold, windy climates, exposed skin is at risk of frostbite within minutes.
2.Wear warm clothing: Choose loose, warm clothing to create insulation for airflow between the clothes. When you go outside, wear a windproof and waterproof jacket to protect it from the wind and rain. Wear clothing that absorbs moisture in your skin, and change out of wet clothing such as gloves, hats, and socks frequently.
3.Wear a hat or bandana: Wear a hat or bandana that wraps around your ears, especially a thick wool or windproof bandana to protect your head from the cold weather.
4.Gloves with fingers: Because gloves with fingers provide better protection for your fingers, choose gloves with fingers. If you only use a finger type, you can put a thin layer of gloves made of PP or other materials on the inside to keep warm.
5.Wear warm socks and midsoles: Choose suitable socks and midsoles that are absorbent and insulated. Also, you can consider that if you want to keep warm, it's best not to make your shoes too tight so that it doesn't affect your blood circulation.
6.Watch for the first signs of chilblains: Be aware of the first signs of chilblains, including a change in color, tingling, and a feeling of numbness. If you have any of the above signs, move to a warmer place immediately.
7.Make a protective plan: When you go out on a cold day, you need to have a plan for self-protection. In case of emergencies outside, bring emergency supplies and warm clothes. If you want to go to a remote place, you should also inform others of your itinerary and expected return time to ensure your safety.
8.Eat a balanced diet and drink water in moderation: Pay attention to a balanced diet and drink water in moderation. Even in cold weather, ensure that a large amount of water is absorbed to maintain body temperature.
9.Exercise in moderation: Exercise in moderation improves blood flow in the body and helps keep you warm. Be careful not to do too much exercise in your life, and don't overexert yourself.
10.First aid for chilblains: In the event of chilblains, first aid must be taken immediately. You can use hot water at 39-40 degrees to soak the frozen part, and do not use fire, heater and other heat sources for reheating to avoid scalding the part. In addition, you can also use your own body temperature or someone else's body temperature to keep warm, or lift the frostbitten part to reduce swelling. If redness, swelling and pain worsen, blisters, blood blisters, bruising, etc. may occur.
It should be pointed out that some "soil methods", such as scrubbing with melting snow, are not very scientific, and after rubbing, they will continue to be stimulated by the cold, which will cause more serious injuries and should not be used.
In short, the key to preventing the occurrence of chilblains is to ensure that the indoor and outdoor temperatures are suitable, and at the same time pay attention to the protection of exposed parts. In a low-temperature environment, pay attention to keeping warm, wear hats, gloves, etc., to minimize the occurrence of frostbite. During this period, it is necessary to closely observe the occurrence of chills, tingling, numbness and other phenomena, and immediately give first aid, and if necessary, seek medical attention immediately to avoid serious consequences.
