Frostnip definition is...

• A. Freezing of skin and underlying tissue
• B. Superficial freezing, reversible
• C. Dehydration due to cold
• D. Numbness only

Answer: (B)

Frostnip is the mild, superficial form of a cold injury, where only the outer layers of the skin freeze. It is reversible because the underlying tissues aren’t damaged if you rewarm promptly. You’ll often see the skin become pale or waxy and feel numb or tingly as warmth returns. This distinguishes it from frostbite, which involves freezing of deeper tissues and can cause lasting damage. Dehydration from cold or the idea of numbness alone don’t capture the full picture of frostnip because the key feature is the superficial freezing that is recoverable with quick warming. To treat frostnip, rewarm the area gradually with body heat or warm (not hot) water, keep it dry and insulated, and avoid rubbing; seek medical care if symptoms persist or blisters form.
