Heatwaves are increasingly threatening global health, with 2,300 deaths reported during a ten-day heatwave in Europe in 2025. Governments in 47 countries have initiated heat action plans, yet social inequalities hinder effective adaptation. Urgent measures are needed to create accessible cooling spaces and implement flexible work policies to protect vulnerable populations.
- 01Heatwaves caused 2,300 deaths in Europe during a ten-day period in 2025.

Heatwaves have emerged as a critical global health threat, with 2,300 deaths recorded in major European cities during a ten-day heatwave in 2025, largely exacerbated by climate change. From 2000 to 2019, heatwaves accounted for nearly half a million deaths annually worldwide. The year 2025 was noted as one of the hottest on record, with severe consequences including glacier melting and unprecedented wildfires. While 47 countries have developed heat action plans, the effectiveness of these measures is often undermined by existing social inequalities. Vulnerable populations, particularly older individuals and those with lower incomes, face greater risks due to limited access to cooling resources and support systems. Research indicates that people adapt their daily activities during heatwaves, but structural barriers often hinder effective coping strategies. Governments are urged to create more accessible cooling spaces, such as community centers and libraries, and to implement flexible work policies that allow individuals to avoid extreme heat. Without significant improvements in heatwave preparedness, the health risks associated with extreme temperatures will continue to escalate.
