Do learn when you're most likely to suffer symptoms. Dry or windy days are worse than rainy days, when residual pollen is washed away. Pollen counts are typically highest in the morning.
Do keep windows and doors closed and use your air conditioner to reduce pollen in your home.
Do wash your hair, face and hands before bed. Remove clothes and shoes before entering the bedroom.
Don't let pets that have been outdoors sleep with you.
Don't expose yourself to allergens to "desensitize" yourself. Learn what triggers symptoms and avoid the triggers.
Don't be afraid to have flowering plants in your garden. Flowers are pollinated by insects, unlike trees and grasses which are wind-pollinated plants. Trees and grasses cause the most allergy symptoms because their pollens are light, small and easily inhaled.
