近期，有户外爱好者违规穿越秦岭鳌太线（鳌山至太白山的徒步线路）后失联，经救援队伍搜救成功获救。然而，其中部分人员在被发现时已出现严重失温症状，并伴随明显幻觉。医学专家指出，失温（即体温过低）不仅会削弱人体基本生理功能，还可能引发神经系统紊乱，导致意识模糊、判断力下降，甚至产生幻觉。在极端寒冷、高海拔、强风和湿冷环境下，人体热量迅速流失，若缺乏专业装备与应急知识，极易陷入危险。鳌太线因地形复杂、气候多变，已被官方明令禁止穿越，但仍有人无视规定冒险进入。此次事件再次警示公众：户外探险必须遵守法律法规，充分评估风险，做好充足准备，切勿心存侥幸。一旦发生失温，应立即寻求庇护、补充热量并尽快联系救援，避免情况恶化。幻觉在重度失温中较为常见，患者可能看到不存在的人或物，听到声音，甚至产生‘反常脱衣’行为（即在极寒中反而脱掉衣物），这进一步加剧了生存风险。因此，提高对失温症状的认知和应对能力，是每一位户外运动者的基本素养。
Recently, several outdoor enthusiasts who illegally attempted to traverse the Aotai Line—a challenging trek between Mount Ao and Mount Taibai in the Qinling Mountains—went missing and were later rescued by search-and-rescue teams. However, some of the rescued individuals exhibited severe hypothermia symptoms accompanied by noticeable hallucinations. Medical experts explain that hypothermia (abnormally low body temperature) not only impairs basic physiological functions but can also disrupt the nervous system, leading to confusion, impaired judgment, and even hallucinations. In extreme conditions—such as high altitude, freezing temperatures, strong winds, and wet environments—body heat dissipates rapidly. Without proper gear and emergency knowledge, hikers can quickly find themselves in life-threatening situations. The Aotai Line has been officially banned for public safety due to its treacherous terrain and unpredictable weather, yet some still disregard the regulations and venture in recklessly. This incident serves as another stark reminder: outdoor adventures must comply with laws and regulations, involve thorough risk assessment, and be supported by adequate preparation. Hypothermia-related hallucinations are common in severe cases; victims may see or hear things that aren’t real and sometimes engage in ‘paradoxical undressing’—removing clothing despite freezing temperatures—which further increases danger. Recognizing and responding appropriately to hypothermia is essential knowledge for every outdoor enthusiast.
