The effects of heat stress on labour capacity have doubled

In the early years of the 21st century, peak summer months of heat stress were cutting human labour capacity to around 90 percent of its full potential. By the middle of the century, this figure has dropped to 80 percent.Rising global temperatures are now having a major impact on those who work outside, or in hot environments – particularly in mid-latitude and tropical regions like South and East Asia, North America and Australia. This trend has occurred despite heavy reductions in man-made CO2 emissions.

Although robots are now handling many human roles, it nevertheless remains a serious issue for the economy and society in general. Heat stroke, heat exhaustion, heat cramps and other conditions are increasing the risk of accidents and injuries. Many sports and leisure activities are being abandoned due to excess heat and humidity, with people forced to spend more and more time indoors. This has boosted the appeal of virtual reality to replace the physical world.
