Year-Round Allergies

Year-round allergies, also called perennial allergies or indoor allergies, are a result of coming into contact with something that you’re allergic to, regardless of the season.

If you’re always sniffling and sneezing, you may think of your home as your place to escape and recuperate from what seems like an endless cold. But some things hidden in your home may actually be the cause of your symptoms.


Hidden symptoms

Common Year-Round Allergy SYMPTOMS

Common year-round allergy symptoms are similar to most other allergies, which include:

  • Itchy, stuffy nose 
  • Runny nose
  • Sneezing
  • Itchy, watery, swollen, bloodshot eyes 
  • Scratchy, swollen throat 
  • Coughing
  • Wheezing 
  • Tightness in the chest


Accurate Diagnosis

If you suffer from these symptoms throughout the year, you’re probably interested in what will stop them more than what’s causing them. But you may not be able to really find relief until you receive an accurate diagnosis. Even allergies to indoor allergens can appear seasonal in nature, since the allergen levels will vary with environmental conditions like temperature and humidity.

For a better consultation with your healthcare professional, here is a list of questions to help guide your conversation and maximize your time.

Common Year-Round Allergy Triggers


Your cat or dog could be causing your symptoms.


Dust Mites

These tiny creatures are the cause of many allergy symptoms.

Dust Mites


Endless sniffles could actually be a reaction to these insects.



An allergic reaction to this fungus is no fun at all.



Why don’t I have symptoms all of the time?

You may think that only pollen causes your symptoms, but other allergic triggers may be involved, too. In fact, 80% of people with allergies are allergic to more than one thing.Everyone has their own unique combination of allergic triggers and not all of them are obvious.

You may experience mild reactions to several things, but they are so small that you don’t notice them on their own. But when you encounter multiple things you are allergic to at the same time, all of those small reactions can add up to the point where you start having symptoms.2,3

Determining if you have allergies and identifying your allergic triggers can help you stay below the point-your symptom threshold-where you start sniffling and sneezing. Learn how your allergic triggers can add up.

How do I find out what I'm allergic to?

How do you know if your perennial symptoms are caused by a year-round allergy or not? Testing can help your healthcare professional determine what may be behind the endless sneezing, so don’t try to manage the problem on your own.

A simple blood test—together with medical history—can help identify underlying allergen triggers, if you have an allergy. Knowing if you’re allergic and what you’re allergic to can help you, or a loved one, avoid or minimize symptoms.
