How does a blanket on only one part of your body keep you warm?

Question

I.e. nights where it’s too hot to be completely under the blanket but too cold to be without a blanket but having a limb covered keeps your whole body warm.

Answer 1

The point is that the majority (>60%) of the body’s heat is maintained through our feet, which is why they rub your legs first if you are ever frostbitten.
Try thinking about why you have to cover or uncover your legs to feel warmer or cooler.
