Exposure of older people to heatwaves


People over 65 years of age, particularly those with chronic medical conditions (such as diabetes and heart, lung and kidney disease), are among the most vulnerable to the health effects of heatwaves. Their exposure to heatwaves can lead to negative health outcomes.


In order to estimate the time evolution of demographics, data from diverse sources was combined in order to obtain estimates of both the spatial and temporal characteristics. This has been subject to limited validation.
