Importance of indoor air humidity

For the benefit of our health, the optimal level of relative indoor air humidity lies in the range between 40 % and 60 %.

It is a known fact that a relative humidity level below 40 % can lead to the drying up of mucous membranes, thus increasing the susceptibility to infectious colds, as dry air has a negative impact on the cleaning function of the inner surfaces of the airways.

A higher level of relative humidity, in the range between 40 % and 60 %, has a positive influence on the comfort of the indoor climate for several reasons: It reduces the concentration of respirable dust in the air, activates the skin’s defences against microbes, lowers the life expectancy of bacteria and viruses, reduces unpleasant odours and prevents the troublesome build-up of electrostatic charges in the room.

However, humidity exceeding 70 % is usually perceived as uncomfortable, presumably because the absorption of oxygen in the blood is reduced in warm, humid conditions. Cold, damp air appears to increase the incidence of rheumatic disorders. It is of particular concern that levels of humidity above 70 % can lead to the rapid growth of mildew in closed rooms.

Adverse effects due to excessively dry indoor air

with regard to comfort

• A decline in performance capacity and in our sense of well-being.
• A greater exposure to dust and microorganisms

with regard to aspects of building physics

• Cracks in parquet flooring, furniture, etc.
• Damage to antiques and out-of-tune musical instruments

with regard to health

• Problems with throat and pharynx
• Dry eyes and skin (itchiness)
• Nosebleeds and headaches

During the cold season, particularly in the winter months, the indoor humidity can drop to uncomfortable levels below 30 per cent!
