Asthma UK [1] is a charity that promotes research to help prevent, control and reduce asthma. It also offers expert advice and support to people with asthma, health professionals and politicians, and works with the individuals and organisations that can make the evidence-based changes needed to curb asthma rates and improve outcomes for the disease [2]. For example, the charity website provides resources aimed at parents and carers to manage asthma among children. It campaigns to ensure the needs of people with asthma are at the heart of decisions affecting their lives [3].
