Tips to Help Manage Your Allergies During High Pollen Count in Chicago, IL

Keep windows closed during peak pollen hours, usually in the morning, and use air conditioning to circulate cool, filtered air. Regularly vacuum your home with a HEPA-filter vacuum and wash bedding weekly in hot water to remove any accumulated pollen.

During high pollen days, enjoy indoor attractions like the Art Institute of Chicago, the Field Museum, or the Shedd Aquarium, where you can escape from allergens in a controlled environment. You can also visit the Museum of Science and Industry or explore the indoor areas of Navy Pier for a fun and comfortable experience.

Try to spend time outdoors in the late afternoon or after it rains, as pollen levels tend to be lower at these times. Wear sunglasses and a wide-brimmed hat to protect your eyes and hair from pollen. If you're planning to be in grassy or wooded areas, consider wearing a mask. After outdoor activities, change clothes, shower, and leave shoes outside to avoid bringing pollen into your home.
