What happens when your skin is exposed to cold?
Frostbite is an injury caused by freezing of the skin and underlying tissues. First your skin becomes very cold and red, then numb, hard and pale. Frostbite is most common on the fingers, toes, nose, ears, cheeks and chin. Exposed skin in cold, windy weather is most vulnerable to frostbite.
How the body reacts when the weather is too cold?

What are some of the problems life faces at cold temperatures?
Here are the top dangers.
- Frostbite. This results from cold temperatures damaging parts of your body, most often your ears, nose, cheeks, chin, fingers, and toes.
- Hypothermia. This conditionoccurs when your body temperature drops below 95˚F (35˚C).
- Heart problems. Cold weather can increase your risk of a heart attack.
Is cold exposure good for you?
