Never sleep near an open window. Keep the windows and vents closed when riding in a car. If you're sensitive to grass, walk on sidewalks and sit on benches, not on the lawn. Have someone else do your yard work. Mowing the lawn or raking leaves can cause an attack if you're allergic to the pollen of grasses, trees, ragweed or mold.
Pollen counts are lowest for an hour or two after a hard rain.
They're highest at about 6 a.m. on sunny days with light winds. Don't hang blankets, sheets or towels out to dry. They're natural magnets for pollen. Cigarette smoke is an irritant that can further aggravate allergy symptoms. Nasal passages naturally swell and secrete more mucus when you drink.
