I think part of the problem with heat is there's only so much you can do to cool down, and it seems to only work for a limited amount of time (e.g if you drink a cool drink, you'll feel cooler for a while but eventually get all hot again). I think this changing (on top of sensory stuff) wears me out more than if it was a constant temperature. Whereas with the cold, you can layer up and get to a preferred temperature for longer. But this is just me theorising, I don't know for sure. ![Smile :)](./images/smilies/icon_smile.gif)
