I agree with NST3, ask the CM (Cabin Manager) and it's just a quick 'ding' to the flight deck and the F/O can tweak the right pack temperature controller up a bit (or down) and you'll be sweating (or shivering) in no-time!
And for the dig about the F/O being there only to adjust the temperature, I am insulted!
