Improving your health
A temperature of 20 to 24 °C and a relative humidity of 40 to 60 percent – people find this kind of indoor climate pleasant and comfortable. These room conditions are also ideal from a medical perspective and provide active health protection for you and your family.
The risk of infection due to germs, fungi, and bacteria is considerably reduced at a relative humidity of between 40 and 60 percent. These conditions create an indoor climate that is optimal for humans and minimizes the risk of flu and common cold viruses.
While warm air in summer can absorb far more water and is perceived as comfortable, the cold winter air reduces the absorption of moisture, which makes the air dry. Relative humidity drops rapidly when the cold, dry air enters your house through the ventilation system and is heated, leaving the indoor climate even drier.
Moisture is extracted from the skin below a relative humidity of 40 percent. This is especially noticeable in the winter months and can make the skin crack and feel itchy. Irritations and inflammations may even occur in extreme cases. But the protective layer around the skin is preserved in sufficiently humid air, which keeps us looking fresh and radiant.
An intact tear film protects the surface of the eye from environmental influences. But tear fluid evaporates to a greater extent if your eyes are exposed to an excessively dry indoor climate. Over time, the tear film may even become thinner or tear. Relative humidity of 40 to 60 percent is urgently recommended to ensure the wellbeing of your eyes.
