Why winter is harder
- Cold, dry air can make the airways tighten, especially when you go from a warm house into the cold.
- Colds, flu and chest infections are the most common winter trigger.
- Damp homes grow mould, and its spores can set off asthma.
- On cold, still evenings, smoke from home fires builds up outside.
Going out in the cold
- Wear a scarf over your nose and mouth on cold, windy days. It warms the air before you breathe it in.
- Breathe through your nose, which warms and moistens the air.
- Keep your reliever inhaler with you. The Asthma Society suggests some people take it before going out in frosty weather. Check what your asthma action plan says.
Exercising in winter
- Warm up for 10 to 15 minutes before you start.
- Exercise in the morning or at lunchtime rather than in the evening, when smoke is at its worst.
- Check the air quality forecast. When it is Poor or worse, train indoors.
Colds and flu
The flu vaccine is free from GPs and pharmacies for people with moderate or severe asthma. If you are not sure whether you qualify, ask your GP or pharmacist. Wash your hands often, and if a cold goes to your chest, follow your asthma action plan and contact your GP.
At home
- Keep rooms warm and dry, and air them for ten minutes each morning.
- Dry clothes outside or in a vented dryer, not on radiators.
- Avoid smoke indoors, including candles, incense and open fires.
When to see your GP
See your GP if you need your reliever more than twice a week, if asthma wakes you at night, or if you can’t do your usual activities. Your treatment may need a change for the winter.
In an emergency
If someone is very breathless, can’t finish a sentence, or their reliever isn’t helping, call 112 or 999.
