What Causes All Year Round Allergies?

Allergic rhinitis is an allergic response. It occurs when your immune system responds excessively to something in your surroundings.

In other words, your body responds to a normally innocuous environmental trigger as if it were a danger, such as a virus.

The symptoms of allergic rhinitis may resemble those of a cold. They may, for example, include:

  • sneezing
  • runny or stuffy nose
  • itchy or watery eyes
  • coughing
  • headache
  • fatigue

You have “seasonal allergies" or “hay fever" if you only have allergic rhinitis during particular seasons of the year. You’re probably sensitive to outdoor allergens like pollen.

If you get it all year, you’re probably allergic to indoor irritants. Learn about the most frequent indoor allergens that cause allergic rhinitis all year.

Pet dander

Dander is composed of microscopic particles of dead skin that peel off animals. It may be found in the air as well as on objects that have come into touch with dogs.

Dander quickly attaches to clothes, furniture, and carpet since it is lightweight, tiny, and has rough edges. As a consequence, it’s simple to spread in a confined space, such as your house.

Some varieties of pet dander are more prone than others to cause allergic responses. According to the American Lung Association, cat allergies are almost twice as frequent as dog allergies.

Furthermore, not all dog breeds are made equal for allergy sufferers.

Some “hypoallergenic" dog breeds may be less prone to allergy reactions.

The American Kennel Club (AKC) recommends dogs with non-shedding coats, such as poodles and schnauzers, for those with allergies.


If you’re allergic to pet dander but still want a pet, see your doctor. Inquire whether specific animals or breeds are more suitable for you.

If you already have a pet, take efforts to reduce dander in your home. As an example:

  • Regularly bathe your pet.
  • Constantly vacuum the floors and furniture.
  • On a regular basis, change and wash your bedding.
  • Keep your pet away from furniture and your bedroom.
  • If you have carpet, consider getting rid of it, or at the very least, vacuum and clean your carpet and rugs on a regular basis.


Mould is a kind of fungus that develops in damp areas. In suitable circumstances, it can grow practically everywhere. For example, it frequently grows on or near:

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

Mould is more likely to grow in a home that has inadequate ventilation and high humidity levels.


To aid in the prevention of mould formation, use the following methods:

  • Damp regions should be ventilated. Use bathroom exhaust blowers, for example, when bathing.
  • Install a dehumidifier in damp or musty places. Make it a habit to clean the dehumidifier’s filters and coils on a regular basis.
  • Remove any sources of excess moisture. Repair leaking pipes or roofing, for example.
  • Maintain the cleanliness of your gutters and other drainage areas around your property.

If mould develops throughout more than 10 square feet of your property, consider calling a professional to clear it up.

Dust mites

Dust mites are microscopic insects that dwell in home dust. They feed on human skin cells and atmospheric moisture. Their bodies, saliva, and faeces all contribute to the dust and may cause an allergic response.


To help keep dust mites at bay, use the following methods:

  • Zippered plastic covers should be used to protect your mattresses and pillows.
  • Wash all of your bedding and area rugs in hot water on a regular basis.
  • Replace carpet with tile or wood flooring in your house.
  • Instead of curtains, use hard window shades such as blinds.
  • Vacuuming your house on a regular basis is essential. Purchase a vacuum cleaner with a high-efficiency particulate air (HEPA) filter and follow the manufacturer’s cleaning or replacement recommendations on a regular basis.


Some insects, like cockroaches, have the potential to cause allergic responses.

If you have cockroaches in your home or office, you might inhale their excrement, saliva, and small particles, just like any other allergy trigger.

Cockroaches are notoriously tough to eradicate. They can survive in practically any environment, although they prefer places with plenty of moisture and food.


To help avoid an infestation, do the following:

  • Don’t leave human or pet food lying around.
  • Cover your garbage cans, rinse your dishes, and clear up any food crumbs as soon as possible.
  • Seal any gaps in your walls and flooring where cockroaches may enter.
  • Repair or remove sources of excess moisture.
  • To get rid of them, use cockroach baits and traps.
  • Use an exterminator on a regular basis.


Avoiding your allergy triggers is an essential aspect of controlling your allergy symptoms if you have allergic rhinitis.

Consult your doctor if you are unsure what is causing your allergic reactions. They will be able to refer you to an allergist for testing. Once you’ve determined what’s causing your symptoms, you may take precautions to prevent them.

Many indoor allergy triggers may be reduced by keeping your house clean and well-maintained. Vacuum your floors and furnishings, clean your upholstery, and change your bedding on a regular basis, for example.

Repairing leaks and other sources of excess moisture may also aid in reducing many indoor allergy triggers.
