As Europe experiences an unprecedented heatwave, the World Health Organization (WHO) is calling for increased investment in healthcare systems capable of withstanding the impacts of climate change. The WHO Director-General emphasized the need for political leaders to prioritize building “climate-resilient health systems” to protect vulnerable populations. This appeal comes amid soaring temperatures across the continent, raising concerns about heatstroke, dehydration, and exacerbation of existing health conditions. The WHO warns that extreme weather events, like the current heatwave, are becoming more frequent and intense due to climate change. Strengthening healthcare infrastructure and preparedness is crucial to minimize health risks and ensure effective responses. The organization stresses proactive measures are essential, rather than reactive responses to crises. This includes early warning systems, heat action plans, and improved access to healthcare services.
