A prolonged heatwave sweeping across Europe has led to a sharp rise in mortality, prompting health authorities in France, Belgium and the Netherlands to report at least 3,700 excess deaths during the period of the extreme temperatures. The figures reflect additional fatalities beyond what would normally be expected, underscoring the health risks posed by prolonged heat—especially for older people and those living in settings with limited access to cooling.

As the hottest weather persisted, officials issued warnings and took public-health measures, while some events were cancelled due to health concerns. Authorities also highlighted that deaths were concentrated among vulnerable groups, including those with limited ability to cope with indoor heat or without adequate ventilation and cooling.

The heatwave’s impact was described as part of a broader pattern of worsening extreme heat in Europe, with officials stressing the need for heat-health action plans to reduce harm during future events.
