Pollens in the air can trigger asthma symptoms in children and adults who are allergic to trees, grass, and weeds. When pollen levels are high, you or your child may need to:

• Stay inside. Pollen levels vary with the seasons, area of the country, and local plants. Watch local weather reports for pollen counts in your area.
• Keep doors and windows closed. People who are allergic to pollens may need to keep their doors and windows closed day and night.
• Wear glasses outdoors. Wearing glasses may keep pollen from getting in your eyes.
• Keep your grass mowed frequently. This may help reduce grass pollen. If you can, have someone else mow your grass.
• Take a shower and change clothing after working or playing outside. Make sure you wash and rinse your or your child's eyes with cool water to get rid of any pollens that have stuck to eyelids or eyelashes.
• Avoid hanging clothes or bedding outdoors to dry.
