Pollen - Asthma Triggers: Asthma
Content provided by the Faculty of the Harvard Medical School
Pollen
Pollen is a powdery substance given off by seed plants and trees in the spring, summer, and fall. If you are allergic to outdoor pollens, you cannot fully avoid them without living in a bubble. But you can lessen your exposure to pollens, at least while you are indoors. Here are some suggestions:
-
Install an air conditioner, which filters the outdoor air and cools the inside so that windows can be kept shut on hot summer days.
-
As an alternative, install a window fan with attached filter.
-
Remove your shoes and outer garments after coming into the house from outdoors; this will help you avoid carrying pollen indoors.
