Poor Pirta. I hope she's either being dramatic or just doing that for pleasure. (wouldn't an ice-cold dunk feel good to you or I after that many PB games?)
That's one of the few big downsides to being an anthro; climatic vulnerability. Instead of just not being used to the local weather, your entire body is geared for something else. Adjusting may be a long and difficult process...if not outright impossible.
