Why is dampness in buildings a health concern?
The majority of the health effects linked to dampness and moisture of buildings are those of the respiratory system. They range from irritation of mucous membranes, respiratory symptoms, and infections to diseases such as asthma and allergy.

Humidity problems in buildings may originate from leaks, condensation, or the ground. Excess humidity promotes the growth of micro-organisms such as moulds and bacteria that lead to release of pollutants into indoor air. Inadequate ventilation may increase humidity and the levels of pollutants. Further research is needed to assess how serious or widespread the problem of building dampness and moisture is at EU level.
