What does frost nip primarily affect?

Frost nip primarily affects areas of the body that are more susceptible to cold exposure and typically includes the ears, nose, and cheeks. This condition represents a mild form of tissue cooling with the skin having surface-level damage, primarily affecting the outermost layers. These areas are often the first to be impacted due to reduced blood flow during cold weather, making them more vulnerable to frost nip.

While fingers and toes are also at risk of cold injuries, they tend to be places where frostbite can occur if exposure continues without protection. However, frost nip specifically refers to the skin's response to cold rather than deeper tissue injury, which is more common in extremities. Thus, the notable focus on the nose, ears, and cheeks highlights the specific anatomical areas where frost nip is most commonly recognized, differentiating it from other cold-related injuries.
