Cold Weather, Dry Air, and Allergy Flare-Ups: What to Do

Allergies aren’t just a spring and summer problem. In fact, some patients find their symptoms worsen during Alberta’s coldest months. Why? Because we spend more time indoors, where allergens like dust mites, mould spores, pet dander, and indoor pollutants become more concentrated.

Dry air can also irritate your nose and throat, making your body more sensitive to these allergens. When you combine heated air from furnaces with closed windows and poor air circulation, allergy flare-ups become more common, even without pollen in the picture.

At UPharmacy, we often see patients confused by cold-weather congestion or itchy eyes that don’t respond to cold medications. That’s because the culprit isn’t always illness; it’s often allergies. 

Tips for Managing Winter Allergies

1. Control Indoor Air Quality

Keeping your indoor environment allergen-free is the first step. Use HEPA filters in your furnace and vacuum, clean ducts regularly, and consider investing in an air purifier. If you have pets, bathe and groom them more often during the winter to reduce dander buildup indoors.

2. Use a Humidifier Wisely

Low humidity can dry out nasal passages and worsen allergy symptoms. A humidifier adds moisture back into the air, helping soothe your respiratory system. However, be careful not to over-humidify—too much moisture can encourage mould growth, which can make allergies worse.

3. Reassess Your Allergy Medications

What worked in the summer may not be enough in the winter. For some, switching from a basic antihistamine to a longer-lasting or combined treatment may be more effective. Nasal steroid sprays can also reduce inflammation and provide long-term relief in dry, indoor environments.

At UPharmacy, our pharmacists assess your allergy symptoms, lifestyle, and medical history to recommend the most appropriate over-the-counter or prescription allergy medications—no doctor visit required.

4. Know the Difference Between Allergies and Colds

Winter colds and allergies can feel similar: congestion, sneezing, fatigue, but they’re not the same. Colds often come with fever and body aches, while allergies persist longer and respond better to antihistamines. If you’re not sure what’s causing your symptoms, walk into UPharmacy for a pharmacist consultation. We can help you tell the difference and guide you toward the right solution.

5. Consider a Personalized Allergy Plan

We offer walk-in or appointment-based care at our Calgary and Edmonton locations. If you have ongoing symptoms, our team can help you build a treatment plan that fits your lifestyle and includes both medical and environmental strategies.
