Low temperatures inhibit mold growth, rendering the organism dormant rather than killing it. While freezing conditions stop mold from reproducing and spreading, the spores remain viable and can reactivate in warmer, more humid environments. For example, mold growing on a damp surface outdoors may become inactive during winter but re-emerge in spring as temperatures rise and humidity increases.
Understanding the relationship between temperature and mold growth is crucial for effective mold prevention and remediation. Controlling indoor humidity and temperature can significantly limit mold growth, protecting both buildings and human health. Historically, cold climates have presented fewer challenges with mold compared to warmer, humid regions. However, modern building practices, which often prioritize energy efficiency, can inadvertently create environments conducive to mold growth regardless of the external climate.
