Pollen and mold can both have a harsh effect on people who suffer from environmental allergies.

Pollen are tiny grains that come from plants and are needed to fertilize plants, according to the American Academy of Allergy, Asthma and Immunology (AAAAI).

Plants often rely on insects to transport their pollen, and some pollen is spread around easily by the wind, according to the AAAAI.

Molds are tiny fungi that can be found almost anywhere, both indoors and outside, according to the National Institutes of Health (NIH). They grow best in damp, humid places.

Mold creates spores that can float through the air like pollen, according to the American College of Allergy, Asthma and Immunology.

Talk to your physician for more information about pollen and mold and where both come from.
