What are the two types of frostbite?

The two types of frostbite are classified as superficial frostbite and deep frostbite. Superficial frostbite affects only the outer layers of the skin, typically causing numbness, tingling, and a pale appearance to the skin. It is often reversible with prompt warming and proper care. On the other hand, deep frostbite extends beyond the skin into underlying tissues, such as muscle and bone. This more severe form can lead to permanent damage and may necessitate medical treatment to prevent complications, such as infection or even amputation.

The other classifications, such as minor and major frostbite or partial and complete frostbite, do not reflect the medical terminology used to describe the varying depths of skin and tissue damage. Likewise, cold-induced and heat-induced frostbite is misleading, as frostbite specifically results from exposure to extreme cold, while heat-induced conditions relate to heat exhaustion or heat stroke.
