THE EFFECTS OF RAIN ON ALLERGIES

During dry spells, trees and other plants release more pollen and there is less moisture in the air to weigh the pollen down, allowing the wind to carry it further distances. Sometimes rain helps weigh down the pollen and wash it away, providing a break from allergy symptoms. But rain also promotes the growth of other allergens such as weeds, grass, mold, and dust mites, which thrive on moisture and humidity and often spike soon after a rainstorm. Heavy rain can also temporarily make pollen allergies worse by breaking up clumps of pollen that then disperse. Steady rain can provide temporary relief from pollen allergies, while heavy downpours can make pollen allergies temporarily worse during a storm.
