5 common triggers of winter allergies

Across the UK, many people experience hay fever (allergic rhinitis) in the spring and summer months, but feel fine the rest of the year. That’s because hay fever is triggered by pollen. Pollen counts are particularly high in the spring and summer. However, many people experience allergies in the winter, too!

You may be asking yourself, what causes allergies in the winter? We’ve prepared a list of 5 common winter allergy triggers to help you keep your symptoms at bay.

Five common winter allergens are:


Mould thrives in damp and humid areas like bathrooms and basements. Mould spores in the air trigger allergy symptoms. Try to keep your home as dry as possible to avoid mould growth and limit allergic reactions.

Dust mites

Dust mites live in furniture, carpets, bedding, and mattresses. Vacuum frequently and wash your bedding in hot water to get rid of dust mites.


Pet dander, saliva and urine cause people with pet allergies to experience symptoms. If you’re allergic to animals be sure to limit your exposure or take an antihistamine before each encounter.


Perfumes, colognes, hairsprays, air fresheners, potpourri and even some lotions are known for causing allergy symptoms. Always apply a small amount to a localised area 48 hours before using a new lotion or perfume to see if it is safe for you to use.

Cold weather

When exposed to cold weather, many people break out in hives. Hives usually cause itching, but might also burn or sting. This allergy is known as allergic urticaria and typically appears on the legs. The welts or hives caused by the cold can be easily controlled by taking an antihistamine.

The best way to control your winter allergies is to identify and avoid your allergy triggers. If that’s not possible, you can take an antihistamine before being exposed to your allergy trigger or once your symptoms start.
