Get ready to discover the top worst states for seasonal allergies. I compiled the data from the Asthma and Allergy Foundation of America (AAFA) top allergy capitals article. From this article, I created averages to come up with these 35 states with the worst allergies in the U.S.
The AAFAs report was compiled by considering the following:
- Spring and Fall Seasonal Allergy Scores
- Over-the-counter allergy medications
- Availability of board-certified allergists in the local area
Worst States for Allergies Grading Scale
The grading scale is 1-100. The higher the number, the worst the state is for allergies based on the reporting criteria above.
To compile the worst states for allergies, I only included states that had an average state grade of 50 points or higher.
Heatmap of the 35 Worst States for Allergies
This heatmap is a good visualization to get an idea of what states and areas are not good for allergy sufferers.
The areas that are blacked out, did not have an average score greater than 50 on the grading scale (not included as a “worst” state).

Worst States for Allergy Sufferers Chart
Overall, there is not a huge difference in the state’s rankings. For example, Louisiana and Missouri are less than half a point from each other.
Although this state chart is busy, it does provide a great visual aid when looking at these states side-by-side.
Preventing Allergy Attacks in the Worst States
Allergens are everywhere. We don’t have to be miserable all the time, there are steps we can take to find relief!
Here are some quick pointers for allergy relief, regardless of where you live (even in the worst allergy states).
Avoidance of Allergens
Knowing what you are allergic to is step 1. Once you know what triggers your allergy, the best way to prevent allergy symptoms is to avoid the trigger.
If you don’t know what you are allergic to, it might be a good idea to start an allergy tracking sheet.
Tracking when you have symptoms (after eating, going outside, visiting certain areas) will give you and your medical provider a great starting point in finding what you are allergic to.
Our bodies release histamine to respond to the “unknown” substance (or allergen). Antihistamines are Anti-Histamine, which can help your body calm down its response.
Common antihistamines are Benedryl, Claritin, Zyrtec, which can be purchased over the counter.
Cleaning to Remove Allergens
Preventing an allergic reaction while living in one of the worst allergy states, might be achieved with cleaning.
Keeping high traffic areas clean, as well as your bedroom can go a long way to limit allergy symptoms. Here are some areas around the house to consider cleaning regularly.
Areas Around the House to Clean for Allergy Symptom Prevention
- All carpets and rugs
- Ensure your vacuum is equipped with a HEPA filter
- Clean/replace vacuum filters often
- Outdoor clothing brought into the house
- Frequent dusting of all horizontal surfaces
- Bedding to include pillows
- Window sills
Shower Away Allergens
Showing at the end of the day, or when you come in for the day is a great allergen prevention method.
Showering will rinse off the allergens (even worst state allergens).
When you are outside, pollen, mold, mildew spores are all around you in the air. These hitchhikers get into your clothes, hair, and hang out on the skin.
Air Filter Replacement
If you have central air or air conditioning in your house, there is an air filter.
This filter is the first line of defense against dust and pollen becoming blown all through the house.
Changing your HVAC filter often increases the heat/cooling efficiency as well.
Consider a HEPA Filter if You Live in a “Worst Allergen State”
A High-Efficiency Particulate Air Filter (HEPA) can filter over 99.9% of allergens from the air you breathe.
We have a WINIX Air Purifier for our home, and we absolutely love it. You can check out the full review here (WINIX PlasmaWave 5500-2 True HEPA Air Purifier Review)
Our family immediately noticed a difference in air quality, and we rarely have to dust.
Keep Windows Closed During Your Peak Allergy Season
Your windows are an instant gateway for the outdoor allergens to enter your home. Don’t let them in, and keep the windows closed!
