Fungus among us all year long
Mold and mildew are tiny fungi. They can live anywhere at any time of the year. So if you have persistent allergic symptoms that occur through several seasons, you might be allergic to mold.¹
There are hundreds of types of molds, but not all of them cause allergy symptoms. The most common allergy-causing molds include Alternaria, Aspergillus, Cladosporium, and Penicillium.²
Places where mold grows
Molds thrive in many environments, both indoors and outdoors. They flourish in damp, humid dwellings. Four primary things contribute to mold growth:²
- Air
- Appropriate temperature
- Moisture
- Food
Mold allergy causes and symptoms
Molds live everywhere, and they have spores. When the spores are disturbed, either by touch or air currents, they can spread rapidly. They flow around in the air — and cause allergic reactions when inhaled. When you inhale mold spores, your immune system treats it as an allergen and releases allergic antibodies to fight it off.¹,²
Typical allergic symptoms like sneezing, watery eyes, and runny nose are all ways your body rids itself of allergens.3
