Most of us, in an effort to conserve resources (and a few pennies) turn down our thermostats at night and when we are away from home. However, good habit may have unintentional consequences if not done properly.
Mold can grow in any environment where there is adequate moisture and a lack of airflow. Keeping the indoor temperature to at least 60° F helps prevent condensation from forming on windows and other cool surfaces. If you have a particularly damp home, ensure there is adequate air flow in closets and around beds. This is just one of the many ways you can mitigate excess moisture from building up in your home. For more tips on how to help prevent mold, and keep your home dry, take a look at these recommendations from the American Lung Association and EPA.
