Days were structured around the heat, waking at 4 a.m. to work outside, then taking breaks and eating a big meal in the middle of the day…
The ascendance of air-conditioning was a transformative force in the South, facilitating the rise of suburbs and making the region less forbidding for companies that wanted to move in. Now, transoms and rising early have been replaced with drive-throughs and attached garages and cranking up the A.C. — for people with the means and jobs that allow it.
“People are so completely dependent on air-conditioning,” said Craig E. Colten, a professor of geography at Louisiana State University. “You run around on our campus and you see people going between classes in shorts and sweatshirts because the air-conditioning is so ramped up.”
Even as air conditioning makes inside activity more possible, it would be interesting to see how much activity during the hot months takes place inside compared to the rest of the year. If people in colder climes spend more time inside during the cold months, is the same true in the South during the summer?
And do not forget the importance of air conditioning for office work.
