Asthma is an inflammatory lung condition which causes narrowing of the airways. Many people find that their symptoms are exacerbated at this time of year.
It is a serious condition which affects 890,000 people in Ireland at some stage in their lives, including one in five children.
There is an asthma-related death in Ireland every six days. However, this can be avoided by ensuring good control of symptoms and reducing risk associated with the disease.
Dr Doireann O'Leary, health blogger and GP with MyCorkGP, joined us for our weekly medical slot to discuss asthma triggers and how to control it.
