Expert Reveals Why Pollen Allergies Are Getting Worse

Pollen allergies are becoming more severe due to a combination of factors, including climate change and increased storm activity. Wind-pollinated trees, which produce vast amounts of lightweight pollen, are particularly problematic for allergy sufferers. As climate change causes longer and more intense pollen seasons, studies have shown that pollen concentrations have increased by 21% since 1990.

Rising carbon dioxide levels also contribute to higher pollen production. In regions like the Southeastern U.S., stronger windstorms, including tornadoes and thunderstorms, exacerbate the problem by keeping pollen airborne longer and breaking it into smaller particles that penetrate deeper into the lungs, intensifying allergic reactions.
