What Causes Frostbite?

Touching Frozen Metal With Bare Hands

Perhaps you've seen those videos of individuals sticking their tongue to a frozen bar or block of ice and getting stuck. It all seems funny, but it can actually prove to be quite harmful. The same can apply for touching frozen metal with bare hands. Because the bar is frozen, and because your hands are bare and far warmer, when they make contact with the frozen bar, a sort of seal is created. Your skin basically seals to the metal of the bar. Depending on just how big the difference is between the two temperatures, you may be stuck there for good. Not only are you prone to developing frostbite during this interval, but your skin is basically starting to die, too.

The cold is making the tissues and skin decay since they're unable to produce enough heat to keep themselves alive. If you're all alone and unable to ask for help, you could end up stuck where you are. This only leads to further exposure to the cold air, which means developing further frostbite along your body.

Medical Conditions That Increase Cold Sensitivity

An individual might be suffering from medical conditions that increase cold sensitivity and not even know it. Medical conditions increasing cold sensitivity include hypothyroidism and Raynaud's phenomenon. In regards to hypothyroidism, the thyroid gland is unable to produce the amount of energy the body needs. It can make you feel weak, tired, and render your body incapable of producing enough body heat to stay warm in the colder temperatures.

Raynaud's phenomenon is especially risky, as it basically exacerbates frostbite. For seemingly no reason, the patient's body reacts strongly to the cold and makes blood circulation extremely difficult for certain parts of the body. This can make frostbite set in extremely quickly and spread over the body at a faster rate than it typically would. If you suffer from any of these conditions, take extra care in the colder temperatures.
