Mold’s Favorite Places in Your Home

Fungi (mold) grow by releasing reproductive cells (spores) into the air, just as plants reproduce by spreading seeds. The airborne spores are invisible to the naked eye, which is a major reason mold is such a problem. It is not uncommon to find hundreds or even thousands of mold spores per cubic foot of indoor air. Spores are extremely small (1-100 microns)—20 million spores would fit on a postage stamp.

Spores can survive harsh environmental conditions, such as dryness, that do not support normal mold growth. In fact, many spores can lie dormant for decades until favorable conditions allow them to spring back to life.

Molds can be found almost anywhere; they can grow on virtually any substance, provided moisture and oxygen are present. There are molds that can grow on wood, paper, carpet, tile, sheetrock, insulation, leather, fabrics, and foods. Molds survive by digesting whatever substrate they are growing on, which is a real problem when it happens to be your floorboards. There is no way to eliminate all mold and mold spores from your indoor environment; the only way to control indoor mold growth is to control moisture. The most common indoor places for mold to take hold are damp areas, such as:

• Bathrooms and kitchens, especially under sinks—particularly leaky ones
• Behind or under appliances that hide slow plumbing leaks (refrigerators, dishwashers, washing machines, etc.)
• Roof leaks
• Around windows where condensation collects
• High humidity areas of your home, such as basements

Often, the first sign of a mold problem is a “musty” odor. You are probably familiar with the smell of mildew—mildew is simply a variety of mold. You could also notice bowed or buckled floorboards, discolored carpet, a new water stain on your wall, or black or white specks—all signs you could be developing a mold problem. But what type of life form is mold?

Mold Can Be Deadly

What many people don’t realize is that mold can make you extremely sick, or even kill you. According to the Environmental Protection Agency (EPA),1 all molds have the potential to cause ill health. The type and severity of your symptoms depend, in part, on the types of mold present, the extent of your exposure, your age and general health, and your existing sensitivities or allergies.

At a 2003 environmental medicine symposium in Dallas, studies of more than 1,600 patients suffering health issues related to fungal exposure were presented. These patients experienced major medical problems, including the following:

• Muscle and joint pain
• Headache, anxiety, depression, memory loss, and visual disturbances
• Immune system disturbances and fatigue
• GI problems
• Shortness of breath

Yet, medical professionals are sometimes not up to speed on how extensive and devastating mold can be to human health, often missing important biological clues that you’re being affected by mold. It is important to be aware of these potential problems because your physician may NOT be, and you need to take the wheel as your own health advocate.
