A major Australian study has found a direct connection between exposure to air pollution and an increased risk of hospitalisation, highlighting the serious health impacts of poor air quality. The research has led scientists and Asthma Australia to recommend stronger action, including banning residential wood fires, gradually ending the sale of new diesel vehicles, and creating a clearer national air quality rating system. The findings underscore the challenges faced by people like Julia Ovens, who lives with severe eosinophilic asthma and experiences frequent hospital visits triggered by pollution, smoke, and strong odours. Researchers say reducing air pollution could significantly improve public health and lower the burden on hospitals across Australia.
