Semi-serious :-) I've worked in a number of cold, sometimes freezing locations in the depths of winter, although not quite as bad as your situation by the sounds of it. Push-ups and exercise does keep you warm and sharp though, should you need it. Sadly there's no quick fix for the opposite situation, when your mind turns to glue in the summer heat.

totally agree on the summer heat - you can always get warm with enough effort, getting cold without external help is simply impossible (I think?)
