Coldest natural temps I've been exposed to for any length of time would have to be somewhere just shy of -40C or so before wind chill. Coldest wind chill I remember was -60 something. Personally I find anything much below -20 is just "damn cold" and it all feels mostly the same.
Also spent a few hours a couple years ago working in a lab's cold chamber. Will admit that even with feeling the chill through the helmet on the suit I was highly curious as to what -180C would feel like on the face. Not curious enough to try, but still.
Not something I would suggest anyone make a hobby of.
