Mold—The Unwelcome Houseguest

Mold—The Unwelcome Houseguest

By Dr. Sarah Liu, Mycology & Environmental Health Researcher

Mold thrives in damp spaces—bathrooms, basements, crawlspaces. While common, certain molds release spores and toxins that seriously impact health.

The Risks:

  • Allergic Reactions: Up to 10% of the population is allergic to mold, with symptoms ranging from sneezing to skin rashes (Journal of Allergy and Clinical Immunology, 2013).

  • Respiratory Issues: Children exposed to mold have a 30–50% increased risk of developing asthma (Mendell et al., Environmental Health Perspectives, 2011).

  • Toxic Molds: Stachybotrys chartarum (black mold) exposure has been associated with neurological symptoms in sensitive individuals.

Prevention & Testing:
Maintaining humidity between 30–50% reduces mold growth (EPA, 2023). Professional inspections help uncover hidden problems behind walls or flooring.
