What effect will warming temperatures have on health? One place to look for answers is Bulgaria. In the summer of 2023, Bulgaria experienced numerous heatwaves, leading to the country experiencing one of the highest rates of heat mortality in Europe. But how are these numbers calculated? How exactly does heat affect us? Who is most likely to suffer from ill health due to heat? And how can we protect ourselves in an increasingly warming world? Along with a panel of experts, Claudia Hammond will explore these questions and more with a live audience at the Sofia Science Festival in Bulgaria. Are we prepared for how rising temperatures will affect our health? This programme aims to find out.
