UN: 'Urgent Action' is needed to protect workers against heat stress as the world warms.

The United Nations stated on Friday that governments and employers must take immediate action to protect workers' health who are exposed to extreme heat. Heatwaves are becoming more frequent and intense due to climate change, and workers around the world are experiencing health effects. The agencies stated this in a major update that was "much-needed" of a 1969 report and guidelines. The report stated that worker productivity decreases by 2-3% for each degree above 20degC. Half of the global population is already experiencing the negative effects of high temperatures.

According to the World Health Organization, and the World Meteorological Association, the health risks are heatstroke, dehydration and kidney dysfunction, as well as neurological disorders.

They said that manual workers in agriculture, construction, and fishing, as well vulnerable populations such as children and older adults living in developing countries were at particular risk.

Ko Barrett, WMO's Deputy Secretary General, said: "Protecting workers from extreme heat not only is a health necessity but also an economic one."

The agencies responded by calling for heat action plans that are tailored to specific regions and industries and developed in collaboration with workers, employers and experts on public health. The agencies noted that unions in certain countries had pushed for maximum working temperatures. However, the agencies also said this was a possibility, but it would vary globally depending on context.

Heat stress is often misdiagnosed by health professionals and first responders.

According to the International Labour Organization, more than 2,4 billion workers worldwide are exposed excessive heat. This leads to more than 22,85 million workplace injuries every year.

Rudiger Krech said at a WHO press conference held ahead of the release of the report, "No one should be forced to risk kidney failure, or even collapse, just to make a living." (Reporting and editing by Hugh Lawson; Jennifer Rigby)
