Which part of the body gets the coldest in space and how is that problem solved?

In space, the part of the body that can get the coldest is often the extremities, such as fingers and toes, due to their distance from the core where heat is generated. This problem is solved by using insulated space suits that incorporate multiple layers of materials designed to retain heat and provide thermal protection. Additionally, these suits often have heating elements to maintain a comfortable temperature for the astronaut while in the extreme cold of space.
