As for an increase in carbon dioxide levels, often associated with the effects of climate change, Phillips said they can "supercharge" some plants' growth, such as ragweed, a common irritant for allergy sufferers.
"More carbon dioxide makes them grow faster, more robustly and makes them release more pollen," she said.
"So that's one of the ways we're seeing the climate change the type of allergens that are in the air. People who didn't have allergies in one area might now," Phillips said.
In order to combat allergies this season, Phillips recommends people attempt to keep allergens out of the home with tactics such as shower upon re-entering the home and immediately taking off outer garments. Additionally, she recommended allergy sufferers avoid early morning outdoor activity, use an air-conditioner, explore new medicinal options and avoid stress and anxiety.
