Ragweed in the air

Ragweed is a flowering plant that’s widespread throughout North America. It releases billions of pollen grains that drift easily in autumn breezes, so even if it’s not growing in your neighborhood, the pollen can travel for miles and linger well into fall. This makes it one of the hardest allergens to avoid, so it’s important to check pollen counts and wear a mask before heading out.

Mold in fallen leaves

Those pretty leaf piles quickly become damp breeding grounds for mold. When leaves are raked or disturbed, spores rise into the air, triggering sneezing and congestion. The best way to avoid this is to wear a mask during any kind of yardwork, and shower immediately after being outside.

Dust from heating systems

The first use of heat each fall stirs up dust, pet dander and other particles that settled in vents during the summer season. That sudden blast of allergens indoors can feel just as harsh as outdoor triggers, so try to replace HVAC filters and wipe vents before turning on the heat.
Autumn’s beauty hides powerful allergy triggers, but by knowing where they come from and taking small precautions, you can enjoy the season without being sidelined by teary eyes and harsh sneezes.
