Researchers find capacity stunted by pollution was restored after introduction of ultra-low emission zone Children’s lungs grew bigger and stronger after the most polluting vehicles were restricted from entering London, a study has found. Examinations of London schoolchildren before and after the introduction of the city’s ultra-low emission zone (Ulez) found a restoration of lung capacity that had been stunted by exposure to pollution.

New DfE statutory guidance on allergy safety in schools states: "Clean air is a core asthma control measure. Good ventilation, air quality monitoring and supplemental HEPA air filtration are essential." Schools are now legally required to have regard to that. 2/
children. Exercise and cold air can also cause symptoms. Common symptoms include coughing, wheezing and breathlessness out of proportion to effort, and a tight chest. An asthma attack occurs when symptoms are severe, and breathing becomes difficult.

Poor air quality worsens asthma and increases asthma attacks, and those in deprived areas with poorer nutrition suffer increased negative health effects from poor air quality. Clean air is a core asthma control measure. Good ventilation, air quality monitoring and supplemental HEPA air filtration are essential, especially when ventilation is limited and outdoor air is polluted. Systematically integrating and embedding clean indoor air into legal health and safety duties, policies, procedures and practices will reduce pressure on staff and ensure consistency and support without too much extra work.

Children and young people known to have asthma should have their own reliever inhaler at school to treat symptoms and for use in the event of an asthma attack. If they are able to manage their asthma themselves they should keep their inhaler on
