憋开新冠肺炎不说,肺部疾病其实一直伴随人类,堪称一大杀手。从肺结核、慢阻肺、SARS到今日的新冠病毒,甚至是普通的流感病毒,都总是侵袭我们的肺。为什么受伤的总是肺?

 

肺的重要性

肺作为人体的呼吸器官,与喉咙、鼻子相连,与外界相通,每时每刻与外界发生着联系,一呼一吸的过程时刻都在进行。肺在吸入空气,完成氧气及二氧化碳吐故纳新的同时,细菌、病毒、真菌、尘埃都有可能随着空气进入肺。其中夹带的肺炎链球菌、葡萄球菌、大肠杆菌、克雷伯杆菌、绿脓杆菌等都可能导致肺炎。

而暴露的呼吸道粘膜极易与空气中的病原体接触,被病原体侵袭、感染。如果机体免疫力较差,或者病原体致病力较强,则可能出现下呼吸道感染,导致支气管炎、肺炎等疾病。事实上,这次新冠肺炎的传染就包含这样一个路径。

一边是娇贵脆弱的肺,另一边则是恶劣且不断变化的外部环境。

 

肺的保护措施

肺部是如此脆弱,而且无可替代,我们能做的就是尽量保护好它。

保护措施如下:

远离污染环境

污染的空气,日常室内环境,比如烹饪煎、炒、炸等中餐烹调产生的油烟等,都不可避免地会影响到人的呼吸系统,当处于污染环境中时,应佩戴口罩。

杜绝吸烟

大部分烟草烟雾中的致癌物会扩散到空气中,这些烟雾颗粒基本小于PM0.5,危害远高于PM2.5。对爱抽烟的人来说,长期经过烟熏和空气颗粒物的残害,咳嗽、痰多、嗓子疼等是常见的事,抽烟者的肺,早就“不堪重负、惨不忍睹了!为了保护好肺,尽量避免吸烟。

锻炼身体

可以选择有氧运动,如散步、慢跑、瑜伽、打太极拳等等,通过这些运动有效改善肺功能,保护好肺部。

将肺功能检查纳入常规身体体检

肺功能检查是早期诊断的重要手段,有助于把握早期治疗的机会。

 

保护我们的肺,就从现在开始。
