How To Beat Your Kid's Asthma explores the challenges of controlling your child's asthma through preventative means. The UK has the highest incidence of asthma and allergies in the world. Numbers have trebled in the last 20 years. It’s a debilitating condition that can kill and it affects over a million children who rely on drugs to relieve terrifying attacks. This two-part series investigates a possible solution that could transform the lives of asthmatics and save millions of pounds. Twelve families with asthmatic children undertake a radical experiment, overseen by a specialist doctor, to see if it’s possible to treat asthma by removing the irritants that cause allergic reactions and trigger attacks. Cameras follow the children, aged between six and 14, and their families as they test out a whole new allergen-free lifestyle for nine weeks.
