Air humidity

Properties

Humidity is defined as the water vapor content of the air. Thanks to its presence, condensation processes (the process of condensing water vapor in the atmosphere) occur and lead to the formation of clouds and precipitation. The amount of water vapor in the air depends on the air temperature (as the temperature increases, the amount of water vapor increases).

Impact on health

Too low humidity

In dry air, the human body draws water from the mucous membranes and skin, leading to dry mucous membranes in the nose and throat. As a result, their protective functions decline, thus increasing the risk of infection. It leads to an itchy and sore throat, breathing problems, coughing, itching, skin inflammation or eye hypersensitivity. Dry air is also harmful to allergy sufferers, making dust and microorganisms float in the air.

Too high humidity

Too much humidity contributes to the growth of mold, fungi or dust mites, which lead to allergies or respiratory disorders.

Standards

The optimal humidity in the room should count 40-60% and is dependent on the temperature:

  • 19-20 degrees C about. 55-60%,
  • 21-22degree C about. 40-45%.
