新冠肺炎疫情肆虐全球,为了健康安全起见,不少大人小孩出街都会长戴口罩。不过有韩国学者指出,小朋友若长期戴着医用口罩,会导致吸入的氧气量减少,恐怕对呼吸系统产生影响,因此呼吁家长多加留意。
韩国环境部早前公布《防霾口罩对健康的影响分析和未来推进方案》报告,韩国成均馆大学研究团队分别针对成人和儿童戴口罩进行测试,从而研究口罩对健康所带来的影响。
研究人员找来了20名儿童作为对象,让他们戴上KF80级别的口罩,再观察他们的健康指标变化。结果发现,小朋友戴了口罩后,每分钟换气量比平常减少约8%(每分钟换气量是指吸入和呼出的空气量),氧气量则减少了约10%。研究指出,每分钟换气量减少,将会令人失眠、头痛、疲惫等问题,影响健康。
负责研究的成均馆大学医学院研究教授金荣旻(音译)表示,每分钟换气量减少不算太大,对健康儿童影响其实也不大,但小朋友若有哮喘等呼吸系统疾病,可能风险较大,因此建议不宜长时间戴口罩出街,留在家中当然更加安全。
