Most Common Allergens in New York City

New York City is quite green with its tree-lined streets and sprawling parks. While the greenery is beautiful, many of the plants found around the city release pollen, which in turn can irritate people. Meanwhile, many New Yorkers are suffering from allergies caused by mold and other substances. Then there are food allergies and numerous other things that can cause reactions. In other words, a lot of things could be causing you to react. By understanding what ​allergens​ might be affecting you, you may be able to take steps to remediate the situation. So let’s take a look at some of the most common allergens found in NYC!

Ragweed and Hay Fever

Hay fever is one of the most common conditions in the world, with millions suffering each year. Many of those suffers can be found in NYC, which regularly experiences high pollen counts. All the pollen in the air, in turn, can set off allergic reactions. Hay fever​ is often caused by pollen from ragweed plants. Unfortunately, this plant is common in and around New York City and pollen counts can be very high. Further, ragweed pollen ​can travel​ for hundreds of miles. Many ragweed species release their pollen in the late summer and early autumn. Even after the plants are done releasing their pollen, it can linger. Pollen often becomes trapped under leaves and when you rake your yard, it’ll be kicked up into the air.

Other Pollens and Hay Fever

While ragweed is often the culprit causing hay fever, many​ other plants​ can cause a reaction. Weeds, grasses, and trees commonly produce pollen that may result in irritation. These plants frequently generate lite, dry pollen that can travel long distances by wind. This makes it more likely that you’ll encounter such pollens.
Grasses, like ragweed, are the most common causes of allergic reactions. Besides ragweed, sagebrush, pigweed, lamb’s quarters, and tumbleweeds are all known to cause allergic reactions. Luckily, tumbleweeds are uncommon in NYC! Unfortunately, common Timothy grass, sweet vernal grass, orchard grass, some species of sagebrush, and other species known for causing allergic reactions can be found in and around New York. Trees too can cause allergic reactions. Groundseltree, for example, is relatively common in the city and can cause reactions. Littleleaf linden, silver maple, and other trees could also be producing pollen, and thus allergens.


Mold is another common allergen found in NYC and across the world. Mold is a type of fungus, and frequently grows in dark, damp areas. The mold’s spores are allergens and can cause a reaction. Mold can grow pretty much year-round. Even in the winter, mold could be growing in your home. Mold often grows in the spring and autumn, especially when it’s damp outside. Mold loves to grow under fallen leaves​ and in other similar conditions. Unfortunately, many people react to even small amounts of mold.


Some people suffer allergic reactions to dust. While New York isn’t all too dusty, dust can still be a problem. This is especially true if you live in an older house or apartment. You can install a HEPA filter to filter out dust and mold. However, you’ll still be exposed to allergens outside of your home.

Food Allergens

Food allergens​ can be particularly dangerous as they occasionally solicit strong reactions. Someone allergic to peanuts or other foods could die if they are exposed to the offending allergens. New York has one of the richest, most diverse food cultures in the world. Unfortunately, that increases the risk of you being exposed. Shellfish, nuts, wheat, and soy are common allergens.

Other Allergens

Many different substances can cause a reaction. Some people are allergic to certain types of perfumes or cologne. Others will reach to chemicals, such as cleaners. Then there’s pet dander. If you live with a pet, you might be allergic to their dander.
Fortunately, you can undergo an allergy test and then undergo allergen immunotherapy, which will help you build up a tolerance. Learn more about identifying and managing your allergens​ ​contact​ Immunotherapy NYC Today!
