WHO warns more than 200,000 heat‑related deaths in Europe

The World Health Organization’s Europe office says extreme heat has caused over 200,000 deaths across the continent since 2022, most of which were preventable. WHO Europe director Hans Kluge described heat as a "silent killer" and warned that Europe is warming faster than any other region.

The agency released updated guidelines urging governments to establish robust heat‑warning systems, provide cooling centres, adjust work shifts to avoid midday sun, and expand urban green spaces. Vulnerable groups – the elderly, children, and people with heart, kidney or respiratory conditions – should receive targeted outreach and hydration support.

Officials in several countries, including Germany, Spain, Norway and Sweden, have reported record‑high May temperatures and a rise in heat‑related fatalities. The report also noted that a strengthening El Niño could intensify future heatwaves. Kluge called for a coordinated, institutional response to protect public health and reduce climate‑driven mortality.
