Staying safe with allergies this winter

As we step into the colder months, we’ve compiled a list of top tips and things to consider during winter if you are managing serious allergies.
Protecting your adrenaline devices
Adrenaline Auto Injectors (AAIs) such as EpiPen or Jext should be kept at room temperature ideally between 15-25°C and should not be refrigerated or frozen. Extreme cold temperatures can damage this medication.
Instead try this:
- An insulated bag to keep medication at the correct temperature. When choosing one, look for a medical-grade insulin bag.
- Do not leave outside or in the car, or near an area that gets very hot such as a radiator or fireplace.
- Check the viewing window regularly to make sure the liquid is clear and colourless. If you believe your AAI is damaged or has been frozen, contact your GP to replace as soon as possible.
- Always carry two in-date AAIs.
If you carry EURneffy please see the patient information brochure for storage instructions.

Indoor allergens
As we spend more time indoors, this means greater exposure to indoor allergens such as dust mites, pet dander and mould. Closed windows and damp corners can make symptoms flare.
Try the following:
- Vacuum and dust regularly
- Wash bedding frequently at 60°C and consider allergen-proof covers.
- Avoid drying clothes indoors without ventilation.
- Reduce mould by opening windows briefly, using extractor fans, and wiping away condensation.
See our Mould Allergy Factsheet for more information.
Festive gatherings
From office parties to family dinners, winter brings plenty of opportunities to celebrate — and that can also mean more risk of accidental exposure to food allergens.
Stay party-ready by:
- Carrying your adrenaline and sharing your Allergy Action Plan with people you’re with.
- Asking about ingredients – See our Eating out with allergies page for more information.
- Reading labels carefully — seasonal favourites sometimes contain unexpected allergens like nuts, dairy, egg or sesame.
- Remembering that alcohol can lower inhibitions and increase the chance of taking risks around food, so stay mindful during festive nights out.
Decorations & Christmas trees
Real Christmas trees and long-stored decorations can harbour dust or mould spores. For some people, this can trigger respiratory symptoms or itchy, watery eyes.
To reduce reactions:
- Clean or dust decorations before bringing them inside.
- Wipe down the tree or let it dry outdoors if it’s damp.
- If symptoms persist, consider an artificial tree.
With a few simple precautions, winter can be a safe and happy season for everyone. Make sure your adrenaline devices are protected, your home environment is allergy-friendly, and you’re prepared when socialising.
