Humans can't endure temperatures and humidities as high as previously thought
Are there any such studies that have investigated, how heat influences the overall human productivity?Obviously, physical work becomes harder and correspondingly less productive during heat. But I also notice a considerable degradation of mental work. Personally, I notice the first symptoms at around 25 degrees. From there on my overall mental performance decreases with every degree.I have never quantified this. So this is pure anecdotal evidence. But I am pretty sure, that more heat correlates with less overall performance and thus leads to a reduction of the GDP.
