Winter Allergies: Why Symptoms Can Still Flare in the Cold Months

Many people think allergies are mainly a spring problem, but allergy symptoms can still flare during winter. Dust mites, mould, indoor pets, poor ventilation, and spending more time indoors can all trigger sneezing, congestion, itchy eyes, runny nose, or sinus pressure.

Because allergy symptoms can overlap with colds and other infections, it can sometimes be hard to know what is causing them.

Why allergies can worsen in winter

During the colder months, people often keep windows closed, use heating more often, and spend more time inside. This can increase exposure to indoor triggers such as dust, mould, pet dander, and air irritants.

For some people, these triggers can lead to ongoing nasal symptoms, sinus discomfort, asthma flare-ups, or poor sleep.

Signs it may be allergies

Allergies may be more likely if symptoms keep returning, happen around certain triggers, or last longer than a typical infection.

Common allergy symptoms may include:

• Sneezing
• Runny or blocked nose
• Itchy or watery eyes
• Post-nasal drip
• Sinus pressure
• Itchy throat or ears
• Symptoms that worsen indoors
• Symptoms that keep coming back

These symptoms can be frustrating, especially if they affect sleep, concentration, work, school, or exercise.

When should you see a GP?

You should consider speaking with a GP if symptoms are ongoing, hard to control, or affecting your daily routine. Medical advice may also be helpful if you have asthma, frequent sinus infections, ear problems, or symptoms that do not improve with pharmacy treatments.

A GP can help assess whether symptoms are likely due to allergies, infection, asthma, sinus issues, or another cause.

What can help reduce triggers?

Simple steps may help reduce indoor allergy triggers. Regular cleaning, washing bedding, managing mould, improving ventilation where possible, and keeping pets out of bedrooms may help some people.

However, if symptoms continue despite these steps, you may need a clearer management plan.

Why proper treatment matters

Untreated allergies can affect sleep, energy, breathing, and quality of life. They may also make asthma or sinus symptoms worse for some people.
