Despite efforts of controlling air pollution emissions, the target levels are routinely exceeded in the UK. While the government is urgently required to address this issue, children are currently being exposed to high levels of air pollution, which in turn is impairing their respiratory health. For my research project, I aim to assess whether or not personal actions, such as changing routes to school, can help children with asthma to mitigate their exposure to pollution and lead to an improvement in their asthma control. In addition, I aim to examine whether certain indoor activities, such as cooking, contributes significantly to a child’s personal exposure and therefore may be amenable to individual action. Information from both indoor and outdoor exposure to air pollution will be analysed and shared with the participants.

About me

I am interested in finding ways that can help children with asthma to improve their asthma control, by understanding the effects of air pollution on the respiratory health.
