Winter Preparation for Allergy Sufferers
Winter Preparation for Allergy Sufferers: Getting Ready for the Indoor Season
As December arrives, the UK officially enters its coldest months – and with them comes a more home-centred routine. During this period, windows remain closed for longer, heating systems run almost continuously, and air circulation decreases, all of which may worsen the symptoms of those living with allergic rhinitis. Preparing your home for the indoor season may be essential to help minimise the impact of the colder months on your health.
Allergens Move Closer in Winter
During winter, people can spend a substantial amount of their time indoors. This prolonged stay in enclosed, poorly ventilated spaces may encourage the build-up of allergens such as dust mites, mould and pet dander. In addition, paints, furniture and cleaning products may release compounds that can irritate the airways and potentially aggravate allergy symptoms. Heated homes without adequate ventilation may create favourable environments for mites and fungi to thrive. Research has shown that levels of house dust mite allergens are generally higher in the winter, which may help explain why some individuals notice their symptoms worsen during winter.
Main Indoor Allergens
Dust mites: microscopic organisms that feed on human skin flakes and settle in mattresses, pillows, carpets and curtains. House dust mites are tiny creatures, about a quarter of a millimetre long, that live off human skin scales. Their particles and waste may be potent triggers for rhinitis and allergic flare-ups.
Mould: appears in damp, poorly ventilated areas, particularly bathrooms, kitchens and spaces near windows. Its spores may spread easily through the air and can cause nasal and eye irritation.
Pet dander: flakes and fur accumulate on fabrics, sofas and carpets, and may remain suspended in the air for periods of time, especially when there is little air renewal. 4 out of 5 patients who live with an allergy to house dust mites are also allergic to pollen and dander.
Together, these allergens may cause allergic rhinitis symptoms such as sneezing, nasal congestion and itchy eyes.
Heating and Ventilation
Continuous use of heating systems without adequate ventilation may be one of the causes of nasal irritation in winter. Warm, dry air may dehydrate the nasal mucosa, while limited circulation may allow dust to concentrate.
Opening the windows for a few minutes each day, even in cold weather, may help refresh the air and lower indoor humidity. Ideally, humidity should remain between 30% and 50%, which may make it harder for mould and dust mites to multiply.
How to Prepare Your Home for the Indoor Season
Bedroom: wash sheets and pillowcases weekly at 60°C and use zipped anti-allergy covers on mattresses and pillows. If possible, avoid carpets and heavy curtains, and ventilate the room daily.
Living room: vacuum sofas, rugs and upholstery twice a week using a HEPA filter. Wipe surfaces with a damp cloth instead of a duster to prevent dust from spreading.
Kitchen and bathroom: use the extractor fan when cooking or showering and leave the windows open for a few minutes afterwards. Avoid drying clothes on radiators and clean areas where condensation forms.
Preventing mould: check dark and damp corners, washing machine seals and tile grout. Clean and dry these areas regularly.
For pet owners: keep animals out of the bedroom and wash blankets and cushions frequently.
Cleaning products: avoid those with strong fragrances and hot-air blowers. Opt for vacuum cleaners with efficient filters and paints with low levels of volatile organic compounds (VOCs).
These small, consistent actions may help reduce exposure to household allergens and keep the air cleaner throughout the winter months.
Managing Allergic Rhinitis Symptoms
Allergic rhinitis (for example, hayfever) causes sneezing, nasal congestion, runny nose and itchy eyes when exposed to particles such as pollen, dust, mould or animal dander. During winter, symptoms are usually linked to indoor allergens rather than the weather itself.
Helpful strategies may include nasal rinsing with saline solution, maintaining lower humidity and, for some individuals, using antihistamines to help relieve nasal and eye symptoms. Nasal sprays may also be recommended under medical advice.
Histallay is a treatment option indicated for managing allergic rhinitis symptoms such as nasal congestion, runny nose and itchy eyes when they appear during the colder months. Allergic rhinitis (hay fever) causes symptoms such as sneezing, runny nose, and itchy eyes when exposed to allergens. Taking the medicine as directed will support appropriate symptom management.
When to Seek Medical Advice
If symptoms persist for several days or interfere with sleep or daily activities, it is important to consult a healthcare professional. Seek immediate medical attention if you experience sudden swelling of the lips, tongue or face, difficulty breathing or swallowing, or a feeling of tightness in the throat - these are signs of a severe allergic reaction requiring urgent care.
When allergic rhinitis goes unrecognised and untreated, it can extend to the lower airways, potentially triggering or worsening asthma. Desensitisation (immunotherapy) is also available for those severely affected through NHS specialist services.
