When spring arrives, so does outdoor pollen. The flowers bloom, the frost melts, and seasonal allergies make their despicable return. Looking out the window to the trees, weeds, and grasses—all while having itchy eyes and a runny nose—you might be tempted to simply curse pollen for those irritating symptoms and resign yourself to an increased tissue and antihistamine budget. However, it’s often not just spring pollen that’s causing that itchy throat and sneezing. In fact, up to 90 percent of people with allergies are allergic to multiple allergens.1

So guess what? It could actually be any number of allergens, from dust mites to pet dander, combining to trigger your symptoms. While you might assume it’s pollen that’s causing you pain, allergies just aren’t that simple.

But you must know that since you are here looking for answers. And boy do we have them for you.

Join us as we break down five common seasonal allergy myths.

1. Spring allergies are only caused by pollen.

While it’s true that there’s an increase in pollen during spring, summer, and even into early fall, it’s wrong to assume that pollen is the only allergic trigger, pop an antihistamine, and call it a day. Not only are you playing a guessing game with your body, but also you might be trying to treat symptoms without knowing what is causing them. That’s a no-no.  

“But Allergy Insider, my allergy symptoms always act up during the spring, and Instagram influencers also complain about their spring allergies, so that MUST be what it is.” Maybe. Maybe not. Consider this: When you encounter multiple substances you’re allergic to at the same time, they can add up, and that’s when you’ll start experiencing symptoms.2,3 This is called the symptom threshold.

Think about your symptom threshold like the rim of an empty cup, and the different substances you’re allergic to as liquids. A splash of pollen, a shot of pet dander, a scoop of dust mites, and the next thing you know, your cup is overflowing and your face is exploding. But, if you can modify this cursed cocktail by reducing exposure to one or two of those allergens, your cup might not overflow, which may mean no itchy eyes, no sneezing, and no repeated trips to the store for more antihistamines.   

Obviously, we can’t control nature (And Mother Nature can get pretty grumpy). But there’s a lot we can do to reduce exposure to sneaky indoor allergens that are just as capable of causing the sniffles.    

2. You can only be allergic to one thing at a time.

Reducing exposure to one or two allergens that you can control (such as pet dander or dust mites) could keep you below your threshold, even when spring pollen is in the air. 

Examples of indoor allergens to which you can help control exposure:

Pet Dander
Dust Mites

3. Only allergic triggers cause symptoms.

It’s not just allergens that can cause allergy symptoms such as itchy eyes, a runny nose, and sneezing. Non-allergic triggers can cause them too. Using a new cleaning product or being around cigarette smoke are a few examples of non-allergic triggers. It’s possible that the symptoms you’re experiencing could be due to a non-allergic trigger, and it’s important to note that these triggers don’t biologically work the same way as allergic triggers, so antihistamines won’t help with relief. Some more examples include:

  • Cigarette smoke
  • Air pollution
  • Cleaning supplies
  • Perfumes and colognes
  • Outdoor dust (e.g. dust storms)


4. It’s impossible to know exactly what you’re allergic to.

One of the most important actions you can take when, or even before, your allergy symptoms start acting up is to get tested for allergies. Specific IgE blood testing will help your healthcare provider pinpoint your allergic sensitizations. You’ll know what is causing allergic reactions and the steps to take to reduce or avoid exposure to them. And guess what? Reducing exposure to those triggers can also help you manage symptoms—or even avoid them altogether. Win-win.

While you can’t get a test to determine those non-allergic triggers we talked about, your healthcare provider can use the process of elimination based on your symptoms and test results. If your test results come back negative, and yet allergy-like symptoms persist, your healthcare provider may suggest you take a look at other possible causes, including your environment, and do what you can to avoid those non-allergic culprits. 

5. Suffering through allergy season is the only option

We just told you some really cool facts about pollen, indoor allergies, and non-allergic triggers what to do about them. The rest is up to you. Impress your friends, educate your healthcare provider, and walk around with your runny nose held high. There’s no reason to suffer.

Oh, and get tested already. You can do so by asking your primary care provider about specific IgE blood testing or exploring the options linked below.
