Answer 1

The same way I end up wearing only a t shirt in freezing weather while chopping wood. Physical exertion produces excess heat, so much so that it can counteract ambient temperature while you work.

Think about it this way, if you work your body hard in normal temperature, you sweat your butt off. This is because the exertion raises your temperature, and you sweat to reduce your temperature because you’re overheating. Now, do the same amount of work in a cold environment… you might start out in 3 layers because you were cold when you started. But, you will shed layers as you get hotter.
