Allergic Rhinitis- Causes of Year-Round Allergies

Year round allergies causes

Year-Round Allergies or Allergic Rhinitis is an allergic reaction, which happens when the immune system overreacts to something in your environment.

In short, the body reacts to the environmental trigger that is usually harmless, as if it was a threat to the body like a Virus.

Some of the common Allergic Rhinitis symptoms are similar to those of a cold. They include:

  • Stuffy or runny nose
  • Sneezing
  • Coughing
  • Watery or itchy eyes
  • fatigue
  • Headache

If you experience Allergic Rhinitis only during certain times or seasons of the year, then chances are you have “hay fever” or “seasonal allergies.” You may be allergic to some outdoor triggers like pollen.

If you experience allergies all year round, you may be allergic to indoor triggers.

This article has mentioned some of the common indoor allergic rhinitis triggers.

Causes of Year-Round Allergies

Pet dander

Dander are tiny bits of dead skin that keep flaking off the animals. These are found on surfaces and in the air where the pets live.

Because these pet dander is microscopic and lightweight and usually have rough edges, they stick easily to furniture, clothing, and carpet. This spreads them easily around the environment, like inside your home.

Certain types of pet dander may trigger allergic reactions more than others. For instance, cat allergies are more common than dog allergies. Also, not all dog breeds may trigger allergies. Some dog breeds, particularly “hypoallergenic” dog breeds, may not trigger an allergic reaction as much.

Cats and dogs that don’t shed much or do not have a heavy coat like schnauzers and poodles can be safe options for people with year-round allergies.

Tips for pet dander allergies:

If you have pet dander allergies but still want to keep a pet, then talk to your doctor. Consult them for any particular breeds that would be safe and less triggering to allergies.

If you own a pet, then take some measures to minimize pet dander in the environment.

For instance:

  • Regular baths to pets
  • Vacuum floors and furniture regularly.
  • Wash and change beddings regular basis.
  • Keep the pet off furniture and away from the bedroom.
  • Get rid of carpet or vacuum and clean rugs and carpets regularly.


Mold is a category of fungus which usually grows in damp places. These can grow almost everywhere if g9ven the right conditions. For instance, it usually grows on the ground:

  • Garages, basements,  and sheds
  • bathroom flooring and walls 
  • air conditioners
  • refrigerators

If your house has a poor ventilation system and high humidity level, the chances of mold in your house increase.

To prevent the growth of mold:

  • Proper ventilation in damp areas. For instance, use an exhaust fan in bathrooms when showering.
  • Install a dehumidifier in areas that smell musty or humid. Always clean the humidifier’s coils and filters regularly.
  • Eliminate the sources of excess moisture—for instance, leaky pipes or shingles.
  • Keep the gutters and drainage areas around the house.

Call a professional to clean if you notice mold spreading across your home in more than 10 square feet of area.

Dust mites

Dust mites can also be one of the causes of your allergies all year-round. These are tiny bugs living in household dust. These feed on moisture in the air and human skin cells. 

These dust mites’ bodies, feces, and saliva also constitute part of the dust and trigger your allergies.

  • Use hard window coverings, like blinds, instead of curtains.
  • Vacuum your house regularly. Invest in a high-efficiency particulate air (HEPA) vacuum cleaner with a filter.


It may sound weird, but yes, even cockroaches and some insects are common allergy triggers. If your workplace or home has cockroaches, you can inhale their saliva, feces, and tiny particles from their body which can cause allergic reactions.

Cockroaches can be notoriously difficult to get rid of from any place. These can easily thrive in any environmental condition; usually, they prefer areas with lots of food and moisture.
