When you lie down perhaps the bed insulates a significant portion of the
back of your body, thus reducing the total surface area through which you
can radiate the heat generated by your body.  To maintain temperature at
a constant value, the body would have to radiate an increased amount of
heat through the remaining surface area of your body.  Anyone out there
remember their thermodynamics well enough to comment?
