Dampness, spills, water leaks, burst pipes, plumbing leaks, storm damage, high humidity, and more, under the right conditions can support the growth of harmful microbes. The more we tightly seal our dwellings to prevent escape of cooled and heated airflow, the further we increase the indoor humidity and toxicity of our breathable air.
As per Shoemaker, over 80% of confirmed CIRS cases are reported to stem from HLA positive people exposed to the interior of a WDB. These poisonous, toxic interiors, can contain fungi, bacteria, actinomycetes and mycobacteria. WDB’s may also be the source of inflammatory producing substances including endotoxins, hemolysins, proteinases, beta glucans, mannans, spirocyclic drimanes, and VOC’s (volatile organic compounds).
As moisture and water is ubiquitous in a built home (kitchens, bathrooms, laundry) it is not hard to inadvertently create the right conditions under which humidity builds to support microbial growth which is harmful to human health.
To this end, water intrusion or spills are recommended to be repatriated to complete dryness within 24-48hrs to prevent fungal spores finding a food source to be able to proliferate.
