Recently, news of a young child being diagnosed with heatstroke (heat stroke) during winter and admitted to the ICU has drawn widespread attention. Heat stroke is typically associated with extreme heat, so how could it occur in cold winter months? Experts explain that heat stroke results from a failure in the body’s thermoregulation system, causing a dangerous spike in core body temperature—and it’s not limited to hot outdoor environments. In winter, if a child stays for prolonged periods in an overheated, poorly ventilated indoor space (such as a room with excessive heating), wears too many layers of clothing, engages in vigorous activity, and doesn’t drink enough fluids, their body temperature can rise abnormally. Infants and toddlers are especially vulnerable because their thermoregulatory systems are not fully developed, making them more sensitive to environmental changes. Symptoms like high fever, altered mental status, or seizures can quickly escalate into life-threatening heat stroke. This case serves as a crucial reminder for parents: even in winter, appropriate clothing, good indoor ventilation, and close monitoring of a child’s condition are essential. If a child shows signs of unexplained high fever that doesn’t respond to cooling measures, seek immediate medical attention to avoid critical delays in treatment.
近日，一则‘幼童在冬季确诊热射病被送入ICU抢救’的新闻引发广泛关注。热射病通常被认为是高温环境下才会发生的重症中暑，为何会在寒冷的冬季出现？专家指出，热射病的本质是体温调节失衡导致核心体温急剧升高，不仅限于户外高温环境。在冬季，若孩子长时间处于密闭、高温、不通风的室内（如暖气过强的房间），或穿着过多衣物包裹严实，加上活动量大、水分摄入不足，就可能引发体温异常升高。婴幼儿体温调节中枢尚未发育完全，对环境变化更为敏感，一旦出现高热、意识模糊、抽搐等症状，极易发展为热射病，危及生命。此次事件提醒家长，即使在冬季，也需注意合理穿衣、保持室内通风，并密切观察孩子的身体状态。一旦发现异常高热且无法降温，应立即就医，避免延误治疗时机。
