Yes. And if you can get it to 102F your body will produce heat shock proteins. Which are good for a whole bunch of reasons, but also can be very bad if you have any tumors, as it makes damaged cells more resistant to apoptosis.

It does indeed increase internal temperature. Perhaps an artificial fever is part of it but I believe the science currently around heat shock proteins.

Hmm. So what about a 30 to 50 minute run wearing sweatpants / hoodie?

I doubt high heart rate is a good mix for high temperature, you want them to balance out, see also homeostasis from high school biology.

I believe that heavy exercise can also increase heat shock proteins, but don't quote me. This info is all readily accessible online.
