Outdoor allergens, like pollen, are a cause of seasonal allergies. They are small, light, and dry, so the wind can carry them for long distances. Pollen levels can vary day-to-day, depending upon several factors, including the weather.
Peak pollen production can occur in early morning, so try to plan outside activities for other times of the day.
Wear an inexpensive painter's mask when you're working in the garden or doing other outside chores.
A quick shower and change of clothes can remove pollens that may have collected on hair or fabrics while you were outside.
When driving, keep windows up and set the air conditioner on "recirculate". At home, keep windows closed and use air conditioning. Be sure to change filters often.
Looking to plant trees on your property? Go with species that don't aggravate allergies, such as Catalpa, Crepe myrtle, dogwood, fir, or redwood trees.
