Europe heatwave kills dozens, strains health systems and power grids

A record-breaking heatwave swept across Europe, with temperatures reaching 40 °C in parts of France, Germany, Austria, the Czech Republic, Poland and Hungary. The extreme heat contributed to a surge in mortality, particularly among the elderly, with French health authorities reporting dozens of heat‑related deaths. The World Health Organization warned that up to 150 million people were exposed to dangerous conditions, and national health ministries cautioned that the death toll could rise as more data become available.

The heat also disrupted electricity generation and transport networks. Power supplies were strained, leading to outages in several regions, while rail services were reduced in Germany's North Rhine‑Westphalia and tram lines were suspended in Leipzig. Rivers such as the Danube and the Po experienced reduced flow, affecting agriculture and hydro‑electric production. In response, experts advised the public to adopt cooling dietary measures, recommending foods rich in healthy fats and fiber—like avocado and nuts—to help stabilise blood‑sugar levels and mitigate heat stress.

Authorities across the affected countries issued warnings to limit outdoor activity, especially during peak heat hours, and emphasized the need for proper hydration and rest. The heatwave is being linked by scientists to climate change, with predictions that such extreme temperature events will become increasingly common.
