Allergic to dust?
People often say they’re ‘allergic to dust.’
In fact, it's dust mites that are the problem, as people can be allergic to a substance in the dust mite droppings. These tiny insects live in the dust that builds up around our homes in carpets, soft toys, bedding, cushions and furniture.
They’re too small to see. And very hard to get rid of altogether.
If you’re allergic to dust mites you’ll have symptoms like itchy eyes, sneezing or a runny nose when there's dust around, and especially if dust is disturbed - like if you’re cleaning or moving furniture.
And if you have asthma too, a dust mite allergy can trigger your asthma symptoms.
There’s no miracle cure against dust mites
There’s no easy way to get rid of dust mites. Unfortunately, research suggests that whatever you do you’re unlikely to make a useful difference to the number of dust mites in your home. And you’d need to put in lot of effort just to get the numbers down a bit.
However, some people with asthma say they’ve noticed a difference by trying a few things.
- regular vacuuming
- airing rooms
- freezing, and then washing, soft toys
- 60-degree washes
- choosing hard floors rather than carpets
- using dust mite covers on bedding
- air filters and purifiers.
There’s nothing to stop you seeing if any of these things help you or your child. If you’re keen to do something, maybe concentrate on the rooms where you or your child spend the most time.
But before you invest lots of time, money or energy on a battle against dust mites, remember that the best way to cut your risk from dust mites is to manage your asthma well every day.
This means you’ll be less likely to react so badly to any of your asthma triggers, including dust mites.
Defend yourself against dust mites with a good asthma routine
Experts agree that the best way to cut your risk of asthma symptoms triggered by dust mites is to stick to a good routine of looking after your asthma well:
- Take your preventer medicine every day as prescribed so you won’t react so badly to dust mites, or any of your other asthma triggers.
- Use your written asthma action plan so you know what to do if dust triggers your asthma symptoms
- See your GP or asthma nurse if you’re getting symptoms three or more times a week to talk about the best ways to manage all your asthma triggers
Top tip: “Talk to your GP or asthma nurse about any nose symptoms you’re getting too. They may suggest you add in a steroid nasal spray,” suggests Dr Andy Whittamore, Asthma UK’s in-house GP. “This calms any inflammation in your nose, and along with your preventer inhaler will help with symptoms in your airways too.”
Asthma UK does not recommend ionisers
Ionisers give out electrostatic charges to clean the air but there's no evidence that they improve asthma symptoms.
Asthma UK doesn't recommend using an ioniser because some research shows that they increase night time cough in children.
