As you may remember I sleep in a fridge. Most people call it a bedroom, but since mine is so cold I can easily cool beer, I call it the fridge. I actually help it along a bit as well by sleeping with my windows open. As if it wasn't cold enough already!
It's not so bad sleeping in a fridge. You just need plenty of blankets. But occasionally even I get cold. Like last night when I woke up at 3am and felt a bit cold. The only part of me that wasn't that cold was my right hand and that was only because it was gloved up (dry environment and sensitive skin on my hand equals nothing good. I use a lot of handcream and need a glove to keep it on).
I got myself another blanket and went back to sleep. And this time I was warm all over!
