In order to recognize allergies to mold, so that you can take the necessary precautionary measures to avoid serious health issues, you need to be able to identify the signs of mold-triggered allergic reactions and learn how to alleviate them. The most common symptoms of mold exposure involve respiratory problems, neurological complaints, and irritations of the skin and the eyes. Well-insulated homes trap moisture indoors, creating perfect conditions for mold growth. Therefore, living in a home with poor ventilation can also increase the chance of developing a mold allergy (or aggravate already existing mold allergy symptoms).
