What is a common result of high indoor humidity levels?

High indoor humidity levels can lead to mold growth, which is a significant concern in indoor environments. Mold thrives in damp conditions, particularly when humidity levels exceed 60%. When indoor air is humid, moisture can accumulate on surfaces, providing an ideal environment for mold spores to settle, germinate, and proliferate. This can have serious implications for both building integrity and occupant health, as mold can produce allergens and irritants that affect respiratory health and overall indoor air quality.

Improved air quality, increased comfort, and enhanced insulation are potential benefits associated with managing indoor humidity levels. However, when humidity is excessively high, these benefits are often outweighed by the adverse effects of increased moisture, which as mentioned, can lead to mold growth and related issues. Thus, understanding the relationship between moisture levels and mold development is crucial for maintaining safe and healthy indoor environments.
