Answer 2

The sun goes down and there is no sunlight or heat from the sun, so it gets colder.

Also, I have my automatic thermostat set so that the house is kept at a lower temperature when I go to bed. I do this to conserve energy and keep my heating costs down.

But in bed the body is less active during sleep so less energy is created from movement. Body temperature is still maintained in a pretty close range by autonomic controls in your body (temperature sensors in your body are around the nape of your neck) and your blankets will help conserve that heat.
