Allergic Reactions

Some individuals can experience allergic reactions after being exposed to certain molds. As an immune response to high levels of mold, sensitive people can develop the following symptoms: fever, runny noses, itchy, watery, burning eyes, coughing, wheezing, sneezing, throat irritation, sensitivity to light, dermatitis, headache, and fatigue. More severe symptoms can develop in people with chronic sinusitis or asthma. According to a 1999 Mayo Clinic Study, most chronic sinus infections are a result of molds.

Irritation

Molds are fungi and digest organic material such as leaves, wood, paper, sheet rock, and insulation. In the process of digestion, molds release spores into the air which are called Volatile Organic Compounds. These compounds are responsible for the moldy or musty smell indoors. When there are high levels of these compounds, irritation of the mucous membranes and the central nervous system can occur. This could result in the following symptoms: headaches, decreased attention span, dizziness, difficulty in concentration and mood changes.

Infections

People with weakened immune systems are at risk for infections due to mold. Although rare, invasive diseases such as hypersensitivity pneumonitis, aspergillosis and trichoderma can occur by inhaling mold spores.

Mycotoxins

Some molds produce toxic compounds known as mycotoxins. When mycotoxin levels are high, any of these symptoms can occur: suppressed immune system, respiratory problems, burning, watery eyes, dry, hacking cough, nose or throat irritation, skin rashes, memory loss, body aches, irritable bowel syndrome, food allergies, headaches, and nasal and sinus congestion. These symptoms can occur in people with no previous allergies.
