More evidence on why air conditioning increases our mental acuity:
(p. A5) Hot weather makes it more difficult for high-school students to learn, a new study suggests.
. . .
The study was circulated by the National Bureau of Economic Research as a working paper by Mr. Goodman and three other researchers.
They found that, on average, every increase of 1 degree Fahrenheit in the average temperature during the school year reduced learning by about 1%.

(Note: the online version of the story has the date June 7, 2018, and has the title “American Students Don’t Learn Well When It’s Hot Outside.” The online version is substantially longer, and in some places has different wording, than the print version. Where the wording of a quoted passage differs, my quotation above follows the print version.)
