I did have a problem with that

Rules on home maintenance and general household practices can vary drastically from one region to the next.  The United States is a large country that encompasses a long list of diverging climates and ecosystems. The ecodiversity from one state to the next can be huge.  That’s why you might see palm trees living in one climate and large boreal pine trees growing in another. What gives rise to this degree of biodiversity is the unique weather each region lays claim to.  A warm and muggy year-round climate dominates many of the southern states, as well as many states out west. When you’re dealing with a climate with high humidity, there are certain steps you must take as a homeowner that someone living up north may never run into.  A common one, which is always a heated topic of debate, is whether or not it’s ‘safe’ to leave your windows open. A lot of people grow up in colder climates where air conditioning is unnecessary and get by for years with fans and good breezes through open windows. These same people move to a hot and muggy environment assuming the same rules apply.  What they don’t realize is that they’re already living in a prime environment for mold propagation—always above 70 degrees, below which mold goes dormant, and often over 70-80% humidity. When they leave their windows open constantly, these spores blow in and settle all over the surfaces of their homes. Since these indoor environments never get dry or cold enough to kill or deactivate the mold spores, they simply grow unabated on every surface that won’t inhibit their growth.  Soon, the homeowner now has a life threatening problem in their home that could have been avoided by simply running an air conditioner a reasonable amount of time. Always be careful knowing that one tip that works well for one area may lead to irreversible life threatening consequences in another.
