The summer can mean misery for people with hayfever and allergies to pollutants such as house dust mites, pet hair and dust.
Allergies can cause itching, sneezing and a runny or blocked nose.
They can even cause asthma, which makes breathing difficult and gives a tight feeling in the chest. Asthma may be set off by year-round allergens such as dust mites, or seasonal ones such as pollen. The Facts is full of useful information on understanding allergies and tips on how to reduce exposure. The British Lung Foundation is the only charity in the UK raising funds for research into the prevention, diagnosis, treatment and cure of all lung diseases.
