What is frostbite?

Frostbite refers specifically to the freezing of tissue fluids, which leads to damage in the skin and underlying tissues. This condition typically occurs when skin is exposed to extremely cold temperatures, especially in windy conditions. The affected areas often include extremities such as fingers, toes, earlobes, and the nose, where blood flow can be restricted in cold environments.

As the tissue freezes, ice crystals can form within the cells, disrupting the cellular structure and function, ultimately leading to potential long-term damage or loss of the affected area. Recognizing frostbite is crucial because prompt treatment can significantly improve outcomes and reduce the likelihood of serious complications, such as infection or necrosis.
