An analysis of mortality data cited by Reuters found that Europe recorded more than 10,000 excess deaths during a late June heatwave.
The study estimated that 10,000 additional deaths occurred across 12 European cities during the period of extreme heat, with temperatures rising significantly above seasonal averages.
The highest number of excess deaths was recorded in cities including London, Paris, Milan and Madrid, where prolonged high temperatures placed additional pressure on vulnerable groups, particularly older people.
Researchers noted that the impact of heatwaves is often underestimated because heat-related deaths are not always immediately identified as such. Extreme temperatures can worsen existing health conditions, including cardiovascular and respiratory illnesses.
The analysis found that elderly people were among the most affected, with women accounting for a larger share of excess deaths in several locations.
Scientists have warned that heatwaves are becoming more frequent and intense due to climate change, increasing health risks across Europe. The Reuters report noted that the continent has experienced some of its hottest periods in recent years, prompting authorities to strengthen heat-response measures.
