POLLEN ALLERGIES

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.

• CHECK YOUR LOCAL POLLEN FORECAST

• Weed pollens

  The most potent and widespread cause of pollen allergy symptoms is ragweed. This tall, branched plant is found throughout the lower 48 states in dry fields and pastures, by roadsides, and at construction sites.

• Grass pollens

  Of more than 1,200 species of grass, the main culprits of allergies are Timothy, Johnson, Bermuda, blue, orchard, and sweet vernal grasses.

• Tree pollens

  When it comes to trees, watch out for hardwood deciduous trees - birch, oak, elm, maple, ash, alder, and hazel.

Smart tips

Beat the clock

Peak pollen production can occur in early morning, so try to plan outside activities for other times of the day.

Cover up

Wear an inexpensive painter's mask when you're working in the garden or doing other outside chores.

Change is good

A quick shower and change of clothes can remove pollens that may have collected on hair or fabrics while you were outside.

Clear the air

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.

Branch out

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.
