While the toxic effects of mold on people is insignificant, the allergic effect is not. Many people are allergic to mold and will experience negative health effects if exposed to elevated quantities of mold. Wheezing, shortness of breath, congestion, headaches, etc. are all possible side effects to mold exposure. Thankfully, this means that if you remove the mold from our home or building, your body’s response should return to normal.
