New IoPPN-led research will examine how extreme hot weather impacts mental health on those living in urban environments, using London as a case-study.

The increased frequency of heatwaves, and the known relationship between extreme climate and mental health, has prompted this research. The project, led by Professor Andrea Mechelli, will use electronic medical records and smartphone-based data, spanning over a period of 15-years, to examine the impacts of extreme heat on mental health in vulnerable urban communities.

The study will look to develop nature-based solutions to the intersectional challenges of climate change and mental health in cities, and forms part of King’s Climate & Sustainability commitment, which aims to rapidly scale up research into the climate crisis and its impact.

The study will assess two complementary sets of data to understand the relationship between climate and mental health alongside map data, meteorological, air pollution and green space data to have the best understanding of the environment, temperature and wellbeing of the participants.

The two datasets will include electronic medical records and measures of mental health collected via personal smartphones.

With active participation from people with lived experience of mental illness, as well as working with organisations within urban communities, this research hopes to understand the relationship between extreme heat in urban areas and mental wellbeing.

Ultimately the project seeks to instigate change to planning policies in London and similar urban centres to benefit the wellbeing of residents and vulnerable communities.
