近日，有滑雪爱好者在社交平台分享经历称，自己仅在雪场滑行半小时，耳朵就出现冻伤症状，引发网友热议。专家指出，冬季户外运动时，暴露在外的皮肤（如耳朵、鼻子、手指）极易因低温和寒风侵袭而发生冻伤。尤其在高海拔或风速较大的滑雪场，体感温度可能远低于实际气温，加速热量流失。冻伤初期表现为皮肤发红、刺痛或麻木，严重时可导致组织坏死。预防冻伤的关键在于做好保暖防护：佩戴防风保暖的帽子、耳罩或头盔，避免长时间暴露；同时注意适时进入室内取暖，并保持身体干燥。一旦发现冻伤迹象，应立即用温水（37–40℃）缓慢复温，切勿揉搓或使用热水直接加热，以免加重损伤。滑雪虽是冬季热门运动，但安全防护不可忽视，合理装备与科学应对低温环境，才能享受冰雪乐趣。
Recently, a skiing enthusiast shared on social media that their ears showed signs of frostbite after just half an hour on the slopes, sparking widespread discussion online. Experts explain that during winter outdoor activities, exposed skin—such as on the ears, nose, and fingers—is highly vulnerable to frostbite due to low temperatures and wind chill. At high-altitude or windy ski resorts, the perceived temperature can be significantly lower than the actual air temperature, accelerating heat loss from the body. Early symptoms of frostbite include redness, tingling, or numbness; in severe cases, tissue necrosis may occur. Prevention hinges on proper protective measures: wearing windproof and insulated hats, ear covers, or helmets to minimize exposure, taking regular breaks indoors to warm up, and keeping the body dry. If frostbite is suspected, the affected area should be gently rewarmed using warm water (37–40°C). Rubbing the skin or applying direct heat (e.g., hot water) should be avoided, as this can worsen tissue damage. While skiing is a popular winter sport, safety precautions are essential—appropriate gear and smart cold-weather strategies ensure a safe and enjoyable experience on the snow.
