labour productivity.

“Too hot” working environments are not just a question of “comfort”, but a real concern for health protection and ability to perform work tasks. For un-acclimatized persons, already at temperatures above 22.5 degrees C the ability to perform at full capacity is reduced, and for acclimatized persons this reduction starts at 26 degrees C (WBGT). The reduction in work ability can be considered a form of “disability” that should be taken into account when assessing the “burden of disease or ill health” caused by global warming.
