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。
