5. Increased Mold spots
Mold spores are a common allergen, and their presence can increase with changing weather patterns. Warmer temperatures and increased humidity create ideal conditions for mold growth. Flooding and heavy rains can also contribute to mold proliferation, especially in damp environments like basements and bathrooms.
The American Academy of Allergy, Asthma, and Immunology (AAAAI) notes that mold spores can be present both indoors and outdoors, and they can be particularly troublesome in warm, humid weather. Higher mold spore counts can lead to more severe allergic reactions in individuals sensitive to mold.
