Causes of Mold and Mildew

• In order for mold and mildew to grow, the environment has to be perfect. The right temperature, moisture, amount of oxygen and nutrients have to be present in order for the bacteria to develop mold and mildew spores. Nutrients like those found in wood, fabrics and paper allow mold and mildew to thrive when combined with proper temperature and moisture. Typically, mold and mildew will grow indoors at room temperature in damp, warm areas like a basement, bathroom or kitchen. They can also grow outside, but can't live in conditions over 100 degrees F or under 40 degrees F.
  
  

Nasal, Throat and Eye Irritation

• Typically, exposure to certain kinds of molds and mildews can cause short-term irritation to the nasal passage, throat and eyes. In addition to these irritations, those exposed to mold and mildew may experience persistent coughing, sneezing and itching, as well as a sore throat, nosebleed, upper respiratory infection and headaches.
  
  

Allergic Reactions

• Not everyone is affected by the harmful effects of mold and mildew. Those who are, however, may be allergic to them. Allergies caused by mold and mildew exposure are known as rhinitis and asthma.
  
  

Neurotoxin Effects

• Mold and mildew can also cause harmful neurotoxin effects, which is damage to nerve tissue. Such damage can lead to visual sensitivity and poor neurological function, according to Dr. Ritchie C. Shoemaker, a family physician from Maryland.
  
  

Cancer

• Exposure to mold and mildew toxins may be a trigger for cancer, according to Luke Curtis from Nexus Magazine. This is because the toxins slowly suppress the immune system and, from there, can damage the heart, lungs, intestines or skin, thus increasing the susceptibility of these areas to cancer.
  
  

Prevent Mold and Its Effects

• Although it is impossible to completely eliminate mold since it is always in the air around us, you can prevent it from growing in and around your house by:
  
  1. Keeping your windows open for at least a half hour each day when the weather is nice. Allowing fresh air to come in will reduce the amount of humidity in your home.
  
  2. Use air purifiers around your home. Air purifiers take out contaminated air, leaving only clean, fresh air for you to breathe.
  
  3. Don't keep wet, porous materials around the home, if at all possible. You should avoid having damp wooden furniture, fabrics and cushions, as they retain moisture and can provide a perfect environment for mold to grow.
  
  4. Clean places that come in contact with water regularly, like sinks, showers, pipes and water bowls for pets.
  
  5. Treat any leaks or water damage around your home as soon as possible.
