Asthma, a disease that causes the airways to contract and restrict, thus blocking the flow of air, can be irritated by mold exposure. The Environmental Protection Agency reports that asthma sufferers should avoid mold because inhaling its spores can trigger asthma attacks. To reduce the likelihood of a mold related incident, the EPA recommends keeping indoor humidity levels between 30 and 50 percent, thoroughly ventilating rooms and removing any absorbent materials that could become infected by mold. Children with asthma are at a higher risk of suffering a mold-related incident if there is a history of allergies and breathing problems in their family, according to Web MD, and studies at Finland's University of Helsinki show the risk of developing asthma can double with significant mold exposure.
Skin and Eye Problems

Exposure to mold can potentially exacerbate existing health issues in those suffering certain illnesses.The Centers for Disease Control state people with chronic lung conditions, like obstructive lung disease, are also more likely to develop respiratory infections, impairing their ability to breathe. The elderly and small children may also be more susceptible to mold related illness and less able to fight off infection, according to the Minnesota Department of Health, and may fall ill with lesser amounts of mold exposure than healthy adults.
