Mold Health Risks

Molds are small organisms found almost everywhere, inside and outside, including on plants, foods and dry leaves. Molds are beneficial to the environment and are needed to break down dead material. Very tiny and lightweight, mold spores travel easily through the air. When molds are present in large numbers, they may cause allergic symptoms similar to those caused by plant pollen.

Exposure to a large number of mold spores may cause allergic symptoms such as watery eyes, runny nose, sneezing, itching, coughing, wheezing, difficulty breathing, headache, and fatigue. Repeated exposure to mold can increase a person’s sensitivity, causing more severe allergic reactions. These problems are worse indoors, where mold causes indoor air quality problems. Certain molds, such as Stachybotrys and Aspergillus, can produce toxins called mycotoxins under certain conditions. Exposure to mycotoxins can cause more serious illness.
