Facts and Myths Surrounding Black Mold Exposure


Mold is a type of fungus that is present almost everywhere including in the air we breathe. It is widely believed that black mold causes serious health concerns. But the truth is that there is no convincing research that suggests exposure to black mold causes severe conditions such as lung disease or cancer. In small amounts, which is normal for the environment, people with healthy immune systems are not at any particular health risks by being exposed to mold.

That said, however, some people are more sensitive to mold spores than others. These people could develop respiratory symptoms if they breathe in these spores. In large amounts, mold spores can cause health problems in almost anyone. This is why it’s essential that if you find mold in your home, you must remove it—and take steps to keep it from coming back

There are many different types of molds—and most molds are black or dark purple in color. When most people use the term “black mold,” they are referring to the type called Stachybotrys chartarum (S. chartarum). This is also known as Stachybotrys atra.

Black Mold and Poor Health

Many people believe that because fungi such as mold release mycotoxins, they can cause several health problems. Some experts suggest that mycotoxins from S. chartarum might result in serious health problems in people who live in contaminated buildings. Mold poisoning is one concern. Other risks include the development of:

  • Aches and pains
  • Mood swings
  • Headaches
  • Nosebleeds
  • Memory loss

Mold exposure can cause other symptoms, however—particularly in people who have allergies or lung issues such as asthma. According to the National Institute of Environmental Health Services, it can cause other health issues:

  • Allergy and irritation
  • Watery, red eyes
  • Runny nose
  • Sore throat
  • Dry cough
  • Skin rashes
  • Wheezing

Age can be another factor in sensitivity to molds. Infants and young children who are exposed to mold in their home are more likely to develop asthma. People with immune systems already weakened from other conditions such as HIV or cancer can also be impacted by mold.

It appears that any kind of indoor mold—not just black mold—can create health issues in some people, particularly infants and children, older adults, people with allergies or asthma, or people with weakened immune systems. Long-term exposure to mold is not healthy for anyone.

Preventing Mold in Your Home

The best way to deal with mold is to prevent it from growing in the first place. Here are some tips:

  • Good ventilation is important in areas where there is moisture. Run the exhaust fan in bathrooms, kitchens, and laundry rooms.
  • Make sure the wet areas in and around your home are draining and drying up properly.
  • Keep water from gathering and sitting around the foundation of your home. Check that there is proper drainage from your home with improvement such as gutters, landscaping, and retaining walls. When it rains, inspect these items to ensure they are working as they should.
  • Waterproof your basement. Ensure that your basement stays dry and comfortable. If it smells musty, this could mean you already have a problem with mold. Have questions about black mold in Gunnison? Contact the experts at SC Environmental today!
