Asthma UK is the charity dedicated to improving the health and well-being of the 5.4 million people in the UK whose lives are affected by asthma. Their vision is to give people control over asthma today, and freedom from asthma tomorrow. Through research, campaigning, health promotion and engagement of the asthma community, they aim to significantly reduce the numbers of people dying, being hospitalised and living lives compromised by their asthma.
