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?<p>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.<p>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.
