Do you know that living in damp houses is living with Bacteria, Fungi right in your bedroom, which is one of the major causes of Asthma and Respiratory diseases:

A 2009 World Health Organisation report entitled "Children Living in Homes with Problems of Damp" stated that:

"Excess moisture leads – on almost all indoor materials – to growth of microbes such as moulds, fungi and bacteria, which subsequently emit spores, cells, fragments and volatile organic compounds into the indoor air. Moreover, dampness initiates chemical and/or biological degradation of materials, which also causes pollution of the indoor air. Exposure to microbial contaminants is clinically associated with respiratory symptoms, allergies, asthma and immunological reactions. Dampness has therefore been suggested to be a strong and consistent indicator of risk for asthma and respiratory symptoms such as cough and wheeze." read more http://www.constructionandproperties.com/index.php/blog/123-living-in-damp-homes-health-risks-prevention-and-remedial-actions.html
