Heat-related mortality in Europe during the summer of 2022

Countries in Southern Europe, including Italy, Greece, Spain and Portugal, suffered most, with heat-related mortality rates ranging between 295 and 211 deaths per million people. Only a small share of heat-related deaths result from heatstroke. More often, heat kills when the human body cannot cope anymore with pre-existing health problems like heart and lung diseases.

The excess mortality is high relative to the more than 70,000 heat-related deaths in Europe during the summer of 2003, after which adaptation strategies were designed and implemented to protect at-risk populations. This urges for reevaluation and strengthening of existing heat surveillance platforms, prevention plans and long-term adaptation strategies, as well as for protection of vulnerable people.
