201808.16 0 Is mold in my house dangerous? It can be dangerous. The degree of risk depends on numerous factors, including the type of mold (some strains are more hazardous to your health than others, although it’s not good for you to be inhaling any type of mold spores), the amount of mold, whether or not you’re allergic to mold, and the state of your health and the health of your family members. Health problems commonly associated with household mold include coughing, sneezing, sore throat, runny nose, headaches or migraines, sinus infections, pneumonia and asthma attacks. Infants, elderly people and those with respiratory disorders like asthma or emphysema are most susceptible to mold-related health problems, but even healthy young adults can be affected.
