北方的冬天非常寒冷,必须靠暖气、空调等取暖。同时,门窗紧闭会使室内空气中二氧化碳的含量增加,影响空气质量。因空调器及其管道中的有害物质污染,以及空气湿度大大降低,常常会发生与“暖气”有关的疾病,称为“暖气病”。冬天干燥,人体呼吸系统的抵抗力下降,供暖以后依旧门窗紧闭,房间温度过高。偶尔出门,突然接触冷空气,很容易诱发气管炎、哮喘、咽炎等呼吸道疾病。特别是原来就有这些慢性呼吸道疾病的人,就更容易旧病复
North winter is very cold, you must rely on heating, air conditioning and other heating. At the same time, tight doors and windows will increase the indoor air carbon dioxide levels, affecting air quality. Due to contamination of air conditioners and their pipes with harmful substances and greatly reduced air humidity, diseases related to “heating ” often occur and are called “heating sickness”. Winter is dry, the body’s respiratory system resistance decreased, the heating is still closed doors and windows, the room temperature is too high. Occasionally go out, suddenly exposed to cold air, it is easy to induce tracheitis, asthma, pharyngitis and other respiratory diseases. In particular, people who originally had these chronic respiratory diseases are more likely to get sick
