Take the following steps, especially during periods of high pollination, to avoid excessive exposure to pollen:
Avoid intense outdoor activities, such as exercise or strenuous work, during the early morning and late afternoon hours when pollen counts are highest. If you need to work outside, wear a pollen and dust mask.
Keep your house clean. Pollen and other allergy-causing agents can be reduced, although not eliminated, through regular cleaning. Use a HEPA vacuum cleaner or if that is not an option upgrade air filtration in your current vacuum to include exhaust filters and multi-layer bags for high allergen containment.
