众所周知,冬季空气比较干燥,白天的平均相对湿度一般都低于50%。加之气候寒冷,室内采暖,居室内的湿度常常只有30%左右。较低的空气湿度对人体健康是不利的,尤其不利于防治呼吸道疾病。湿度过低时,水分蒸发加快,干燥的空气易夺走人体的水分,使人皮肤干裂,口腔、鼻腔黏膜受到刺激,出现口渴、干咳、声哑、喉痛等症状,甚至诱发咽炎、气管炎、肺炎等病症。 As we all know, winter air is relatively dry, the average relative humidity during the day are generally less than 50%. Coupled with the cold climate, indoor heating, indoor humidity is often only about 30%. Lower air humidity is detrimental to human health, especially not conducive to the prevention and treatment of respiratory diseases. When the humidity is too low, the water evaporates faster, the dry air can easily take away the body’s moisture and make the skin dry, the mouth and nasal mucosa are stimulated, throat, cough, dumbness, sore throat and other symptoms, and even induced pharyngitis, trachea Inflammation, pneumonia and other diseases.
