Too Hot to Learn? the risk of heat-stress in primary schools

Over the past few weeks, Europe has experienced a rare period of extreme heat. These high temperatures have already caused elevated mortality rates. The risk of heat-related illness is not only for those outdoors, exposed to sunlight and heat, but under certain conditions, heat-related illness (and even death) also applies to those indoors, where the temperatures can rise to dangerous levels.

As part of a long-running study on the quality of indoor environment quality in schools, we are continuously monitoring 270 classrooms through a sensor network. The data is also useful to study the risk of heat-stress over the past few weeks.
