With the freezing temperatures the Lakeland is reaching this winter, frostbite is a real concern as it can set in within minutes.
Frostbite is the freezing of the skin and tissues below the skin. It occurs when a person is exposed to freezing temperatures [ 0°C (32°F)] or lower for too long and can be easily prevented.
According to Alberta Health Services (AHS), frostbites severity can differ from case to case with temperature, wind chill, and humidity all being crucial factors
The most common places frostbite is seen are on the feet, hands, ears, nose, and face.
Frostbite occurs in several stages as the part is exposed to the cold.
- Superficial frostbite
- Deep (severe) frostbite
Frostnip is a mild form of frostbite, continued exposure leads to numbness in the affected area. As your skin warms, you may feel pain and tingling.
Frostnip doesn’t permanently damage the skin. You can treat frostnip with first-aid measures, including rewarming the affected skin. All other frostbite requires medical attention because it can damage skin, tissues, muscle, and bones. Possible complications of severe frostbite include infection and nerve damage.
Superficial frostbite appears as reddened skin that turns white or pale. Your skin may begin to feel warm — a sign of serious skin involvement.
If you treat frostbite with rewarming at this stage, the surface of your skin may appear mottled. And you may notice stinging, burning and swelling. A fluid-filled blister may appear 12 to 36 hours after rewarming the skin.
Deep (severe) frostbite:
As frostbite progresses, it affects all layers of the skin, including the tissues that lie below.
Your skin turns white or bluish-gray and you may experience numbness, losing all sensation of cold, pain or discomfort in the affected area. Joints or muscles may no longer work. Large blisters form 24 to 48 hours after rewarming. Afterward, the area turns black and hard as the tissue dies.
There are specific conditions that lead to frostbite which include:
- Wearing clothing that isn’t suitable for the conditions you’re in — for example, it doesn’t protect against cold, windy or wet weather or it’s too tight.
- Staying out in the cold and wind too long. Risk increases as air temperature falls below minus 15 C, even with low wind speeds. In wind chill of minus 27 C, frostbite can occur on exposed skin in less than 30 minutes.
- Touching materials such as ice, cold packs or frozen metal.
According to Healthwise staff, frostbite is described by degree, from the first degree through the fourth degree.
- First-degree frostbite freezes the outer part of the skin, and it usually does not cause lasting problems.
- Second-degree frostbite freezes all layers of the skin. It causes numbness followed by aching and throbbing pain. Blisters appear, filled with clear or milky fluid.
- Third-degree frostbite freezes the deep layers of skin and tissues below the skin. The skin turns white, pink-purple, or blue-grey and is hard and frozen “like a block of wood.”
- Fourth-degree frostbite freezes muscles, tendons, and bones. Patches of red or blue skin turn dry, black, and rubbery. Blisters may appear as small blood spots under the skin.
Here are ten tips to help you stay safe and warm:
- Limit time you’re outdoors in cold, wet, or windy weather. Pay attention to weather forecasts and wind chill readings. In very cold, windy weather, exposed skin can develop frostbite in a matter of minutes.
- Dress in several layers of loose, warm clothing. Air trapped between the layers of clothing acts as insulation against the cold. Wear windproof and waterproof outer garments to protect against wind, snow, and rain. Choose undergarments that wick moisture away from your skin. Change out of wet clothing — particularly gloves, hats, and socks — as soon as possible.
- Wear a hat or headband that fully covers your ears. Heavy woolen or windproof materials make the best headwear for cold protection.
- Wear mittens rather than gloves. Mittens provide better protection. Or try a thin pair of glove liners made of a wicking material (such as polypropylene) under a pair of heavier gloves or mittens.
- Wear socks and sock liners that fit well, wick moisture, and provide insulation. You might also try hand and foot warmers. Be sure the foot warmers don’t make your boots too tight, restricting blood flow.
- Watch for signs of frostbite. Early signs of frostbite include red or pale skin, prickling, and numbness. Seek warm shelter if you notice signs of frostbite.
- Plan to protect yourself. When traveling in cold weather, carry emergency supplies and warm clothing in case you become stranded. If you’ll be in remote territory, tell others your route and expected return date.
- Don’t drink alcohol if you plan to be outdoors in cold weather. Alcoholic beverages cause your body to lose heat faster.
- Eat well-balanced meals and stay hydrated. Doing this even before you go out in the cold will help you stay warm.
- Keep moving. Exercise can get the blood flowing and help you stay warm, but don’t do it to the point of exhaustion.
