Why You Still Have Allergy Symptoms in the Winter

You might expect winter to give you a break from seasonal allergies. However, for many people, indoor allergies can make this time of year just as uncomfortable.

After all, many people spend much of the winter indoors with windows closed and the heat running. This creates the perfect environment for common indoor allergens to thrive.

At Allergy A.R.T.S. in Amarillo, Texas, our team of specialists provides expert care and support for allergies and asthma. Part of our goal is to help you understand your allergy triggers, so you can take steps to manage your environment and symptoms.

We’ll take a look at the most common indoor allergens, how to spot the difference between colds and allergies, and steps you can take to keep your home (and sinuses) healthy.

What’s driving my indoor allergies?

Common triggers for indoor allergies include:

Dust mites

Dust mites are microscopic creatures that live in the dust that accumulates on bedding, upholstery, and carpets. Stuffed animals are another favorite hangout for these tiny critters.

They feed on flakes of human skin and thrive in warm, humid environments—like heated homes during the winter.

When you snuggle under blankets or turn on the heat, dust mite allergens can circulate through the air, triggering sneezing, congestion, and itchy eyes.

Indoor mold

Mold spores are another common culprit. They can grow in damp areas, such as basements, bathrooms, and around windows, where condensation builds up.

Poor ventilation in winter exacerbates the challenge of controlling mold. Breathing in mold spores can cause nasal congestion, coughing, and wheezing—symptoms that can mimic a lingering cold.

Pet dander

Your furry friends also contribute to winter allergies. Since pets spend more time indoors with you, exposure to pet dander (tiny flakes of skin, saliva, and fur proteins) can increase in winter.

Even if you aren’t technically allergic to your pet, their dander can mix with other indoor allergens and irritate your sinuses.

Poor indoor air quality

Modern homes are built to be energy-efficient and airtight, but this can also trap allergens inside. Forced-air heating systems can blow dust, dander, and mold spores throughout your home.

Household cleaning products, air fresheners, and other scented items can add to the mix. If you don’t change air filters regularly, you may be breathing in more irritants than you realize.

How to tell if it’s allergies or a winter cold

It’s easy to confuse allergy symptoms with a cold or sinus infection. However, allergies typically cause itchy eyes, clear nasal discharge, and recurring symptoms that last for weeks or months.

Colds, on the other hand, usually resolve within 7-10 days and often come with fever or body aches. Only your doctor can confirm this, but if your symptoms persist and follow a predictable pattern every winter, allergies are likely the cause.

Tips to reduce winter allergy symptoms

There are several steps you can take to reduce your exposure to indoor allergens:

Use a HEPA filter

High-efficiency air filters effectively trap airborne allergens, thereby improving indoor air quality. Use them for your furnace and consider using a vacuum cleaner with HEPA filtration.

Wash bedding weekly

Clean sheets, blankets, and pillowcases in hot water to kill dust mites. Invest in zippered allergen-resistant pillow and mattress covers to limit dust mite contact.

Dust and vacuum regularly

Use a vacuum with a HEPA filter to remove pet dander and dust from floors and upholstered furniture. Dust hard surfaces with a damp cloth, and don’t forget to wipe down the windowsills.

Control humidity

Keep indoor humidity between 30–50% to discourage mold and dust mites.

Groom pets regularly

If you suspect a pet allergy, check in with our allergy team for an evaluation. Otherwise, regular grooming helps minimize dander buildup and irritation.

And while cats and dogs are a popular focus, don’t forget smaller household members such as guinea pigs. Keep their bedding clean and well-aired.
