  1. The feet, hands and head have special blood vessels that are used to control body temperature. With hands under the covers and head on a fluffy pillow, it is no wonder that a feet needs to be out.

    • (Not that I'm belittling what you're saying, just adding on) I think it could also be that, when you stick a limb out, the blanket forms gaps that allow air flow underneath, thereby cooling further.
