Are You Sick?

Symptoms of Frostbite

• Cold, tingly and painful skin.
• Pale, hard, numb skin. It can be serious. It always needs medical care after re-warming.

Cause of Frostbite

• Health Conditions. You are more likely to get frostbite if you have Raynaud's Disease, diabetes or have had frostbite in the past.
• Clothing. Wearing wet clothes makes frostbite worse. Touching bare hands to cold metal during freezing weather can cause frostbite right away.
• Length of Time in Cold. You are more likely to get frostbite the longer you are in freezing weather. Wind-chill causes you to get frostbite quicker.
• Other Causes. Some medicines, smoking, alcohol and recreational drugs all raise your risk of frostbite.
