why mold is bad for health
Why mold is bad for health becomes evident when you consider how indoor mold exposure can affect air quality, trigger allergic reactions, and worsen chronic respiratory conditions. According to Mold Removal Lab, damp environments are fertile ground for mold growth, and leaving moisture unchecked increases the chance that occupants will experience symptoms. In homes with visible spots or musty odors, the phrase why mold is bad applies to both immediate discomfort and long term risks.
