How can dust mites affect your asthma?
If you suffer from asthma and are exposed to lots of house dust mites, you’re more likely to have an asthma attack or asthma symptoms.
Asthma is caused by an inflammation of your airways, which can be triggered by an allergic reaction, for example to dust mites. Asthma symptoms may include coughing, wheezing, difficulty breathing and a tight chest.
Allergic reactions are caused by allergens such as dust mites, pollen or mould. These allergens aren’t harmful but they can trigger reactions in certain people who are allergic to them. Allergic reactions can cause symptoms in your nose, lungs or chest, eyes, or skin.
