Mold is a big problem in many homes, but many people are unaware of the potential risks. There is some debate regarding how mold affects humans, but much research—and common sense—tells us that sharing a home with mold isn’t beneficial.
Everyone checks for mold on the shower curtain, under the sink, or in the basement, but mold can grow just about anywhere. Mold can be found in drywall, in the roof or ceiling (if leaks are present), and even in one’s Christmas tree. One study found that Christmas trees can breed mold, quietly releasing millions of spores into the room, potentially causing winter allergies and asthma attacks.
Different Types of Mold
Allergenic Molds: Allergenic molds are on the low end of the danger scale. They only cause problems for those with asthma and a predisposed allergy to the specific mold. Children are more likely to have mold allergies than adults.Five Common Indoor Molds:
Alternaria: Commonly found in your nose, mouth, and upper respiratory tract; can cause allergic responses. Aspergillus: Usually found in warm, humid climates, and a common occupant of house dust; produces mycotoxins; can cause lung infections. Cladosporium: This very common outdoor fungus can find its way indoors to grow on textiles, wood, and other damp, porous materials; triggers hay fever and asthma symptoms. Penicillium: A very common species found on wallpaper, decaying fabrics, carpet, and fiberglass duct insulation; known for causing allergies and asthma; some species produce mycotoxins, one being the common antibiotic penicillin. Stachybotrys: Extremely toxic “black mold” that produces mycotoxins that can cause serious breathing difficulties and bleeding of the lungs, among other health problems. Thankfully, less common in homes than the other four, but not rare; found on wood or paper (cellulose products), but not on concrete, linoleum, or tile.“Mold illness” refers to the variety of health problems that can occur from mold exposure. Although mold allergy symptoms are the most common reaction caused by exposure to mold, mold can cause illness—such as infections, irritation, and toxic reactions—without an allergic reaction. Infections caused by mold can lead to a variety of problems, from flu-like symptoms to skin infections and even pneumonia.
