That seems pretty straight forward to measure, you just take the temperature of people who exercise regularly (say three times a week) and compare that to people who work physically demanding jobs, and to people who work in office jobs, and don't exercise.

(I would almost expect, that the study authors know of something like that, and would have mentioned it, if it were the case.)

I would have expected it to be explicitly mentioned if considered.

While we don't consider that sedentary, compared to the physical nature of the majority of jobs and lives these people would still be considered sedentary. I think a better comparison would be people who are doing long distance through hikes since their time under tension is extensive and the large distances they travel each while under load would be more respective of per-industrial lifestyles.

I imagine apple has this data already with their apple watch data collections.

There is no body temperature measurements in Apple Health from the Apple Watch, but that would definitely be an interesting data point were it available.

Yes, but also a potential privacy concern since if you have temperature data for a female, you could use it to pinpoint when ovulation may be occurring. I can only imagine that due to some of the recent privacy issues with cycle tracker apps that information might already be exploited for some nefarious advertising campaign.
