“干燥空气”是办公室类环境中主要且大量的室内空气质量投诉。尽管尚未提供投诉的明确定义，但感知的“干燥空气”和相关呼吸影响的因果关系仍在争论中。“干燥空气”的感知在没有相关受体的情况下在语义上是混乱的，但是模仿了感觉刺激的原始状态，如冷却感觉。“干燥空气”也可能与另一种常见的室内空气质量投诉“闷热空气”混淆，后者模仿没有新鲜空气和鼻塞的感觉。40多年前，低室内空气湿度（IAH）被认为是“干燥空气”投诉的原因，而室内污染物被认为是寒冷季节可能加剧的致病因子。然而，许多研究表明低IAH的不利影响和高IAH的有益影响。在这篇文献综述中，我们试图回答，“什么是室内环境中的“干燥空气”及其相关的因果关系。许多研究表明，这种感觉不仅是由长期暴露于低IAH引起的，而且还与室内空气污染物同时发生，并可能因室内空气污染物加重气道和眼睛泪膜中的保护性粘膜层而加剧。一般人群中鼻和气道的传染病也可能导致整体投诉率，包括其他风险因素，如人群年龄，药物使用和外部因素，如当地环境湿度。低IAH可能是老年人群中感知“干燥空气”的单一原因，而某些室内空气污染物可能在易感人群中起作用，除了鼻部疾病的基线贡献。因此，感知到的“干燥空气”与眼睛和喉咙干燥、某些室内空气污染物、环境湿度、低IAH和鼻部疾病相关。
“Dry air” is a major and abundant indoor air quality complaint in office-like environments. The causality of perceived “dry air” and associated respiratory effects continues to be debated, despite no clear definition of the complaint, yet, has been provided. The perception of “dry air” is semantically confusing without an associated receptor but mimics a proto-state of sensory irritation like a cooling sensation. “Dry air” may also be confused with another common indoor air quality complaint “stuffy air”, which mimics the sense of no fresh air and of nasal congestion. Low indoor air humidity (IAH) was dismissed more than four decades ago as cause of “dry air” complaints, rather indoor pollutants was proposed as possible exacerbating causative agents during the cold season. Many studies, however, have shown adverse effects of low IAH and beneficial effects of elevated IAH. In this literature overview, we try to answer, “What is perceived “dry air” in indoor environments and its associated causalities. Many studies have shown that the perception is caused not only by extended exposure to low IAH, but also simultaneously with and possibly exacerbated by indoor air pollutants that aggravate the protective mucous layer in the airways and the eye tear film. Immanent diseases in the nose and airways in the general population may also contribute to the overall complaint rate and including other risk factors like age of the population, use of medication, and external factors like the local ambient humidity. Low IAH may be the single cause of perceived “dry air” in the elderly population, while certain indoor air pollutants may come into play among susceptible people, in addition to baseline contribution of nasal diseases. Thus, perceived “dry air” intercorrelates with dry eyes and throat, certain indoor air pollutants, ambient humidity, low IAH, and nasal diseases.
