Black mold can pose health risks, particularly for people with allergies, asthma, or weakened immune systems, but it is not usually deadly for most healthy individuals. It produces spores and sometimes mycotoxins that can cause respiratory symptoms, irritation, and allergic reactions. Prolonged exposure to any indoor mold, including black mold, may lead to asthma, lung inflammation, mood changes, or immune system effects. However, black mold is not considered more dangerous than other molds in general, though it should be removed promptly to prevent health issues and damage to the home.
