Default 冬季注意缺氧综合症

每到冬季,有些人感觉呼吸不畅,感冒次数增多,健尔马足疗机三代,甚至还出现嗜睡、反应迟钝、疲劳乏力、精神不振、胸闷、气短、头痛等症状。
专家指出,上述症状的出现,与换季时人们对外界的反应有关,但另一个重要诱因是氧气供给不足。冬季气温低, 人们呆在封闭空间里的时间大大增加,又不注意通风换气,室内空气不能及时
更换和补充,空气质量下降,加之冬季人们室外活动的减少,身体缺氧时有发生,专家谓之“缺氧综合征”。缺氧 时间过久,人体可能会出现一系列不适,严重时甚至可能危及生命。据国家有关部门检测,通常在氧气较好的地方 氧气浓度为21%左右,密闭卧室经过人们一夜睡眠后,氧气浓度会降到17% 19%,甚至更低。
开窗通风是预防“冬季缺氧综合征”最简便易行的方法。
