本文转自【杭州交通918】； 近日，杭州一女子小丽在睡觉时用热水袋捂在脚边取暖，第二天醒来，她发现脚背竟起了一个大大的水 泡，3天后，水泡自行破溃，创面发红化脓，疼得她无法正常走路，最终只能前去就诊。医生提醒：大 家一定要警惕冬季高发的"隐形杀手"——低温烫伤！ 通常情况下，皮肤接触44℃-50℃的热源，持续6小时以上，就可能造成烫伤；接触55℃的热源，只要1 分钟，就会出现明显烫伤痕迹。 它的可怕之处在于：初期皮肤只是发红、发痒，没有明显的疼痛感，很容易被忽视；等发现水泡、溃烂 时，损伤已经深入皮肤深层，甚至累及皮下组织、肌肉，愈合周期长达数周甚至数月。 这4种行为，大家千万别再做！ 暖宝宝/热水袋直接贴皮肤 哪怕是"低温款"，持续贴敷4小时以上，就可能烫伤；建议隔一层薄衣服（如秋衣、毛巾），且每1小时 更换一次位置。 电热毯整夜通电 睡前打开预热，上床后务必关掉电源；切忌边充电边使用，也不要在电热毯上堆放厚重被褥。 天冷了，谁还没个"取暖神器"傍身？睡前暖手宝捂被窝、追剧时电热毯铺身下、老人久坐靠热水袋暖 腰、孩子写作业暖宝宝贴衣服……这些看似温和的取暖方式，其实藏着"致命隐患"——低温烫伤！ 低温烫伤比 ...
