The name given to the leg you stick out of the duvet when you're too hot to regulate you're temperate back down.

Leg + Regulator = Legulator

The act of regulating your body temperature in the cold or heat while sleeping using one leg or foot.

For example: If you are too hot under your blankets, you stick a leg/foot out from beneath the blanket allowing you to cool off without having to give up the warmth of your bed.

Reverse example: If it is too cold, you can partially cover your body/leg/feet with a blanket to help warm to the right temperature.
"I was having trouble sleeping because I was too hot, so I uncovered my leg to legulate my temperature."
