"...heat stress probably cost the Australian economy nearly A$7 billion in 2013-2014 through productivity losses..."
Regardless of the reason, productivity loss from heat was a major cost to the Australian economy in 2014. Of 1,726 respondents sampled randomly from the Australian population, 7% did not go to work on at least one day in the previous 12 months because of heat stress.
Ten times that number (70%) went to work but thought they were less efficient. On average people were less productive at work because they felt heat stressed on 10 days per year and cumulatively also lost about 27 hours per year. When the sample is extrapolated to the Australian working population, heat stress costs the nation A$6.9 billion per year in lost productivity.Click Here to Read the Full Article
