為什麼加濕......用於減少毒菌


Illnesses are transferred by various pathogenic microorganisms — especially viruses, bacteria and fungus. Bacteria can self-reproduce. Viruses, such as the constantly changing influenza virus which triggers the real flu, require a host for reproduction. In the process, they destroy the latter’s cells.

Illnesses are transferred by various pathogenic microorganisms — especially viruses, bacteria and fungus. Bacteria can self-reproduce. Viruses, such as the constantly changing influenza virus which triggers the real flu, require a host for reproduction. In the process, they destroy the latter’s cells. The body’s own defense cells of the immune system have to eradicate cells which have been attacked by viruses. Bacteria such as salmonella or legionella can for example trigger illnesses through their metabolic products. The washing of hands and regular ventilation reduce the transference possibilities through microorganisms. In order to protect others, coughing should be done hygienically into the crook of the arm.

In our climate, most germs are transferred through the air or by direct physical contact (RKI). A balanced relative air humidity significantly reduces the number of germs here. According to Prof. em. Dr.-Ing. habil. U. Marmai (Iselt et al) the “optimum range of relative air humidity is between 40 and 60%在正常環境空氣溫度下。“

許多研究(Harper,Noti,Lowen等)證實,增加的空氣濕度顯著降低了流感病毒的活性。因此,在實驗研究(NOTI)中,來自國家職業安全和健康研究所的美國科學家(NIOSH)表明,即使相對的空氣濕度超過40%,也顯著降低了病毒的傳染潛力。在現實的條件下,研究人員在冬季期間調查了在室內空氣中的傳輸路徑以及各種相對空氣濕度的病毒的傳染潛力。在低至23%的低空氣濕度下,大約三個季度具有超過一小時的傳染性,而大約是大約。43%的空氣濕度水平不到四分之一,趨勢下降。
