Black mold is the subject of much fear, stemming from the health issues many people believe it can cause. Thanks to recent research, we now know that black mold is not as dangerous as many think. However, it can still lead to certain respiratory problems, particularly if a person with a mold allergy, sensitive skin, or a pre-existing respiratory illness is exposed to the fungus.
Immune system reactions sometimes cause irritated eyes that are watery and itchy. Usually, this is due to the production of histamine, a compound that increases vascular permeability. This means that more fluid is traveling through the capillaries into tissues, causing many of the classic symptoms of an allergic response. Histamine is also a mediator of itching, so an excess can lead to more itchiness.
