Surprisingly Bad Effects of Relative and High Humidity on Human’s Health and How to Solve It

Relative Humidity: Why is it unsafe?

When they say about the issue of humidity, usually there are tons of prejudices, rumors on low humidity and how it can affect human’s health. However, only a few pay attention to how relatively high humid level could bring negative effects and the incidence of allergies Moreover, oftenly it causes respiratory infections.

According to experimental studies which were made on airborne-transmitted infectious viruses, the survival or simple infectivity of these organisms is very low. The exposure to relative humidities is between 40 and 70. Other epidemiological studies showed the tie between the number of respiratory infections or absenteeism and the relatively soaring humidity of the residence (houses, office, school, etc.)

Thus, it goes without saying that the square meters and the amount of allergenic mite and fungal populations as well surely depend on the high humidity.

Moreover, the worst part stands for serious chemicals: relative humidity also has the rate of outgassing of formaldehyde from different indoor building materials. In addition, the rate of formation of salts and acids from nitrogen dioxide and sulfur, and the last but not least the rate of formation of ozone.

These are just a few reasons why the influence of high humidity on the abundance of allergens, pathogens, and noxious chemicals should be taken into attention. It’s obvious that indoor soaring humidity levels must be considered as a factor of indoor air quality. So, is there any more important than health?
