> Do you think people were terribly uncomfortable at ambient temperatures due to their physiology before AC was invented? Yes, absolutely. I grew up without AC and now I jokingly tell my fiance my entire career has been motivated to ensure I maintain access to AC the rest of my life. I grew up in a very cold place (MN) compared to most - the cold didn't matter much to me. I'm a t-shirt in 40 degree weather sort of guy. The hot summer months were absolute utter hell though, even with fans and sleeping in the basement/etc. To this day I think this had a huge effect on my sleeping patterns and thus other health problems later on in life. I do think one of the elephants in the room is the obesity issue. I certainly have noticed I get a lot hotter with 40lbs extra on me. When the average American is overweight I'm sure this has moved the "herd preference temperature" down a couple degrees the past few decades.
