This Graphic Shows You How to Treat Frostbite
If you're not careful out in the cold of winter, you could end up getting frostbite which can cause serious harm to your extremities or areas of exposed skin. This graphic shows you how to treat it before it gets bad.
As the image courtesy of advice site the Art of Manliness explains, you need to identify frostbite by sight and feel. Affected areas will start out sore, but they can become numb, leading you to think there's nothing wrong simply because there's no pain. Watch for skin that starts red, then becomes unusually pale and firm.
Once you've identified the area, dry it off and keep it covered. Avoid further exposure to the cold as soon as possible. Once you can find warm shelter, heat some water to 100-112 degress, so that's its warm but not too hot. Soak the affected skin, adding warm water to maintain the temperature as necessary. Continue soaking the area until the color and feeling returns. As the source link below explains, it's also a good idea to seek medical attention immediately, as the damage may run deeper than you can immediately see.
