Seasonal Allergy Management and Treatment
- Monitor pollen and mold counts. Weather reports in newspapers and on radio and television often include this information during allergy seasons.
- Keep windows and doors shut at home and in your car during allergy season.
- To avoid pollen, know which pollens you are sensitive to and then check pollen counts. In spring and summer, during tree and grass pollen season, levels are highest in the evening. In late summer and early fall, during ragweed pollen season, levels are highest in the morning.
- Take a shower, wash your hair and change your clothes after you’ve been working or playing outdoors.
- Wear a NIOSH-rated 95 filter mask when mowing the lawn or doing other chores outdoors, and take appropriate medication beforehand.
- If symptoms persist then consult an allergist.
