Frost nip is most commonly associated with which environmental conditions?

Frost nip occurs when skin is exposed to cold temperatures, typically in conjunction with wind, causing the surface layers of skin to freeze. The condition is particularly associated with high wind and severe cold because the combination exacerbates the body's heat loss. Wind can remove the insulating layer of warm air around the body, leading to hypothermic conditions even at temperatures that may not seem dangerously low. This is crucial to understand in the context of athletic training, as athletes may be at risk during outdoor activities in cold, windy environments. Proper protective measures, such as wearing layered clothing or windproof gear, can help mitigate the risk of frost nip.
