It was reported that Richard Nixon would crank the thermostat down and
have a fire lit in the White House in the summer.

Jimmy Carter cranked it down in the winter and wore a sweater.

I still not sure which of the two was nuttier. [g]

Wes in Tucson, where it's estimated the temp will be 110 today (a
record for the date) and the dew point will be in the 30's.

I went to school in Texas. They have fans on even during the colder
winter days. I live in Michigan. Here, most people sleep under
comforters (heavy blankets) even in the summertime.

If allergies are the concern I think you will need electrostatic filter.
As for opening the windows, if it makes you feel good, go ahead. Just
because you are filtering the air at times does not mean you gotta turn
your house into a bubble of sorts. Live life.

You are correct. It makes little sense. But nobody's perfect.
