During winter, many households use gas water heaters, coal stoves, or electric heaters for warmth. However, doctors warn that using certain heating devices—especially combustion-based ones like gas burners, charcoal fires, or coal stoves—in poorly ventilated, enclosed spaces can easily lead to carbon monoxide (CO) poisoning. Carbon monoxide is a colorless, odorless, and highly toxic gas. When inhaled, it binds to hemoglobin in the blood, blocking oxygen delivery throughout the body and potentially causing unconsciousness or even death.Therefore, it’s crucial to ensure proper ventilation when using such heating methods. Even in cold weather, experts recommend opening windows for 5–10 minutes every 1–2 hours to allow fresh air circulation and reduce the risk of harmful gas buildup. Installing a carbon monoxide detector is another effective preventive measure.Doctors strongly emphasize that if anyone experiences symptoms such as dizziness, nausea, fatigue, or confusion, they should immediately turn off the heating device, open windows for ventilation, evacuate the area, and seek medical attention promptly. Staying warm should never come at the cost of health or safety.
冬季寒冷，许多家庭会使用燃气热水器、煤炉、电暖器等设备取暖。然而，医生提醒：在密闭空间内长时间使用某些取暖设备，尤其是燃烧型设备（如煤气、炭火、煤炉等），极易导致一氧化碳中毒。一氧化碳是一种无色无味的有毒气体，吸入后会与血液中的血红蛋白结合，阻碍氧气输送，严重时可致昏迷甚至死亡。因此，在使用这类取暖方式时，务必保持室内通风，定期开窗换气，确保空气流通。即使天气寒冷，也建议每隔1-2小时开窗5-10分钟，以降低有害气体积聚的风险。此外，安装一氧化碳报警器也是有效预防措施之一。医生特别强调，一旦出现头晕、恶心、乏力、意识模糊等症状，应立即停止使用取暖设备，迅速开窗通风，并尽快撤离现场就医。安全取暖，不能只图暖和，更要注意健康与生命安全。
