The WHO's report is particularly striking as it marks the first detailed examination of heat stress in workplaces since 1969, underscoring the changing climate dynamics. Rüdiger Krech, the WHO's director of environment, climate and health, characterized the findings as a crucial reminder that the dangers of high temperatures extend beyond mere discomfort. When body temperatures exceed 38°C for prolonged periods, the risk of severe health issues, including strokes and kidney failure, significantly increases.

Global warming's impacts are indisputable, with the World Meteorological Organization reporting the last decade as the hottest on record. This reality has repercussions for productivity, revealing that worker efficiency declines by 2% for each degree rise in temperature above 20°C. In addition, the WHO noted an uptick in workplace accidents during heatwaves, particularly in Europe, where a notable increase in incidents was reported during the recent summer heatwave.

With construction and agricultural workers bearing the brunt of heat exposure, some European nations are taking proactive measures to safeguard laborers. In Italy, recent legislative efforts have halted outdoor work during peak heat hours, while Swiss regions paused construction activities to prioritize worker safety.

The WHO's findings, however, extend beyond the workplace, indicating that vulnerable populations such as the elderly, chronically ill, and children also face significant health threats amid rising temperatures. Some regions, like Germany, have systems in place to dismiss schools during extreme heat, yet frequent such interruptions are becoming harder to justify with the growing frequency of high temperatures.

As schools resumed session amid sweltering conditions recently in Switzerland, there are rising calls from educators for renovations to include better ventilation and air conditioning to create conducive learning environments. Krech has sparked discussions on whether school uniforms should be redesigned for better comfort in the heat, emphasizing the need for holistic solutions to address the adverse effects of climate change on education and wages.

While adaptation is necessary, it typically requires financial investment. Unfortunately, many governments are prioritizing other budget areas at the expense of climate resilience strategies. Krech warns that neglecting necessary changes might lead to greater economic losses when health and productivity decline due to extreme heat.

Therefore, the report advises a collaborative approach to adaptation involving governments, employers, local councils, and health authorities. The WHO stresses that the time for action is now, urging for changes that prioritize the well-being of workers and ensure their safety and effectiveness in the face of increasing heatwaves.

As climate change continues to affect global temperatures and extreme weather patterns become a normalized part of life throughout Europe and beyond, the imperative for worker protection against heat stress has never been greater.
