迄今为止尽管空气离子对机体的作用尚有不同看法,但大量研究表明,空气离子具有广泛的生物和医学效应,在一定浓度下的空气轻阴离子对人体呈现有益的作用,而阳离子呈现不良的作用。因而空气离子在卫生保健及防治疾病等方面都正在被广泛探索和应用。停留在轻阴离子和浓度很低(小于50个离子/cm~3)、阳离子浓度很高的环境中,或在拥挤的室内停留一定时间后,人们会感到头昏、恶心、不适、甚至易怒、忧虑,以及使患风湿、支气管哮喘、枯草热者病情加重。也有学者报道在热环境下空气阴离子可改善体力劳动者的心血管、热调节功能与主观感觉。
Although there are different opinions on the role of air ions in the body so far, a large number of studies have shown that air ions have a wide range of biological and medical effects. The air light anions at a certain concentration show a beneficial effect on the human body while the cations show an adverse effect . Therefore, air ions in health care and disease prevention and control are being widely explored and applied. People stay dizzy, nauseous, upset, or even irritable after staying in light anions and in very low concentrations (less than 50 ions / cm 3), in high cation concentrations, or in crowded rooms for a period of time , Anxiety, as well as suffering from rheumatism, bronchial asthma, hay fever. Some scholars have reported that the air anion in the hot environment can improve the cardiovascular, thermal regulation function and subjective feeling of manual workers.
