Mold exposure causes sneezing, skin irritation, coughing, runny nose and watery eyes, according to MedicineNet. It can also cause shortness of breath and fever, reports the Centers for Disease Control and Prevention. People who suffer from chronic lung illnesses may suffer from lung infections when exposed to mold.
Mold produces irritants, toxins and allergens that cause health complications in humans, explains the Illinois Department of Public Health. Mold exposure is connected with upper respiratory tract symptoms, such as wheezing and coughing, explains the CDC. People who suffer from asthma may have asthma symptoms, while people who are likely to have immune-mediated conditions may suffer from hypersensitivity pneumonitis.
The most common symptoms of mold exposure are allergic reactions, states MedicineNet, which include nasal congestion, skin rashes and itching, according to the Illinois Department of Public Health. People with mold allergies may suffer from asthma attacks that cause tightness in the chest, wheezing and shortness of breath. People with weak immune systems may get infections in the lungs, eyes and skin after exposure to mold. In rare cases, mold exposure may cause pneumonia. Molds also give off volatile organic compounds, which can cause headaches, dizziness and fatigue, and they can produce mycotoxins that cause problems for humans.
