Frostbite

Frostbite is when your fingers, toes, noise and your ears get so cold, the freeze. Eventually they will get numb and fall off. This is why it's important to pay attention to your body.

Symptoms: The body part (typically ones farthest away from the heart, like toes and fingers) is numb and cold. It may have a slight grayish-yellowish look to it.

First Aid: Warm the body part up. Use your hands, armpits, heat pads, anything to get them warm. Getting the victim to a warm place will help. Do Not rub, stroke or massage the frozen skin. Doing so may cause chunks of skin to fall off. Not a pretty site.

Prevention: Stay warm. Wear gloves, make sure your feet stay warm and dry. It's a lot harder to stay warm when you are wet.
