Different sizes of pollen particles could mean more problems for your allergies

Smaller pollen particles that are known to cause problems with allergies will linger in the air longer.

COLUMBUS, Ohio — Pollen is in the air and depending on the type of pollen, it might be sticking around. 

The average size of a pollen particle is 25 microns, which is equivalent to the size of a strand of human hair. 

Pollen can range in size, some may be as small as 2.5 microns or can be as large as 200 microns. Plants and trees all produce different types and sizes of pollen. 

Smaller pollen particles are usually found in more common types of allergens like weeds, trees and grasses, and can travel easily in the wind. 

Larger-sized pollen particles have a difficult time traveling or staying in the air. 

"We have a lot of corn here in Ohio and corn pollen is going to be toward the larger end of the range, so it won't travel as far. So, corn pollen allergies usually you must be right next to the corn field to have symptoms," said Dr. Andrew Dang, a Premier Allergy & Asthma board certified allergist,

Weather conditions can also play a factor in how easily pollen can be a bother. Rain and higher humidity can make it difficult for pollen to be released. Particles can be lifted by air currents during the day and travel far distances before settling when conditions calm down. 

Studies have found that the early morning hours, before sunrise, is when most pollen is released from plants.
