Could you tell me what happens if your body is exposed to mold for a long period of time?

Mold exposure: It would be hard to tell. We have been living in the environment with lots of aero allergens and pathogens and not all of us responds to the exposure the same way. It also depends on the exposure load too. You might not have any problems. You might get sensitized or allergies to the molds, or get an invasive lung infection. If you already have environmental allergies, you should avoid it.

Fungus: Mold and fungi are the most prevalent living thing on the planet. We are all exposed to mold in some form at all times. Most often it causes no harmful effects and can even be important for our health such as yeast used to ferment alcohol and raise bread or make cheeses. Other times it may take advantage of us like athletes foot or candida yeast infection. Allergy or infection can also occur.
